Brake types

The bicycle market is growing and developing rapidly. Every year more and more new technologies, solutions and spare parts appear. Therefore, some details are outdated and cannot withstand the competition. Today we will discuss those types of bicycle brake systems that are actively used in our time.

So, bicycle brakes are of the following types:

  • Drum.
  • Rim (in turn divided into: cantilever, tick-borne, hydraulic, and V-break).
  • Disk (there are: mechanical and hydraulic).

According to the popular classification, the first type is called a pedal brake, and the rest are called manual brakes. Now let’s analyze each of the types separately.

Drum brakes

This type is known to many from childhood. It was these brakes that were installed on the legendary bike “Ukraine”, as well as children’s bicycles “Eaglet”, “Lastochka” and others. It is often referred to as rear or pedal. This is true because it is located in the rear wheel hub and is activated by pedaling in the opposite direction of travel. As a result of rotation of the carriage in the opposite direction, the brake shoes installed inside the drum are spread apart and press the drum. Braking occurs due to the frictional force between the pads and the drum. Today this type is used in children’s bicycle models, as well as in budget models of adult city bicycles.

Drum brakes advantages:

  • Durability. It is mainly due to the fact that moisture, dust and dirt practically do not get into the closed-type mechanism.
  • The drum brake does not wear the wheel rim.
  • Simplicity. These brakes do not need constant maintenance.
  • They work even in case of wheel curvature, do not require fine adjustments.
  • Heavy weight.
  • It takes a lot of effort to brake.
  • Inability to use on multi-speed bike models.
  • The presence of a dead zone. Braking is not possible when the connecting rods are in vertical position.
  • If the chain falls off the sprocket, the brake will stop working.
  • Bicycle drum brakes do not give you the ability to brake suddenly. When every second counts, it matters.

Drum brakes are used on simple walking bicycles. In case the chain falls off, for greater safety, many put an additional brake of another type on the front wheel.

Rim Bicycle Brakes

The drum brake bushing is gradually becoming obsolete. And the leading positions in the market are occupied by rim and disc brakes. Rims are most popular today, as they are more practical than drum and cheaper than disc. The principle of operation of this mechanism is quite simple: when the cyclist presses the handle located on the handlebar, a cable is pulled, which transfers the force to the brake levers, and they, in turn, press the pads against the wheel rim. Here, again, frictional force is at work. Now let’s talk in more detail about each type of rim brake.

Cantilever brakes

The mechanism consists of two levers, each of which has brake pads. The levers are attached to the pivots on the fork. With the help of two rods, the cable moves the levers that press the pads. The device is reliable and simple, but it is less and less common on modern bicycles. Other types, with a more efficient mechanism, are gradually replacing it.

Caliper brakes

This type of bike brake is most commonly used on road bike models. Their name perfectly characterizes the design: the pads are pressed against the rim by means of curved levers that look very much like pincers. Tick-borne brakes, like cantilever brakes, are gradually becoming obsolete.

Hydraulic rim brakes

Unlike the previous two types, the design of such brakes does not include rotating levers on which the pads are attached, and cables that drive these levers. The principle of operation is slightly different here. The brake lever located on the handlebars contains a fluid cylinder. When pressed, it transmits pressure through special tubes to the two cylinders mounted on the fork. These cylinders push the pads perpendicular to the rim, causing friction and braking. Bicycle brakes of this type are very effective, so they are used in trials. Due to heavy weight, difficulty in maintenance, poor modulation (ability to dose the braking force with the handle) and repairability in difficult weather conditions, rim hydraulic brakes have not taken root in other types of cycling.

V-brake brakes

Since this type of rim brakes is the most common on the modern market, let us dwell on its advantages and disadvantages noted by users.

  • Simple and very efficient design that provides good braking power.
  • Lightweight compared to drum and disc brakes.
  • Low cost.
  • Mechanism durability.

There were also some drawbacks:

  • Reduced efficiency when moisture and dirt get on the rims.
  • Acceleration of rim wear in case of contamination.
  • Inability to use wide tires.
  • If the wheel is uneven (has “eights”), this type of brakes are difficult to adjust for high-quality performance.

Disc Bicycle Brakes

So, a disc brake consists of a rotor (disc) and a caliper (brake machine). The rotors are available in diameters from 140 to 220 mm. The higher this indicator, the larger the lever arm and the more efficiently the brake works. The caliper is mounted on a frame or bushing. Pads are installed inside it, which are driven by special pistons. Bicycle disc brake pads are made from organic materials or metal filings. The first option allows for smooth braking and quickly grinds in, and the second grinds in for a long time and wears out longer.

Mechanical

  • Provides much more powerful braking than rim.
  • Allows you to control the braking force.
  • They work in any weather. Dust, dirt and moisture practically do not affect the quality of braking.
  • Do not wear out the rim.
  • Does not interfere with the use of wide tires.
  • Work effectively on a curved rim.
  • Long serve.
  • Do not need special maintenance.
  • Rotor aligns much more easily than hydraulic brakes.
  • Ropes do not need special operation, unlike hydraulic lines.
  • Can’t be repaired in the field without special tools.
  • Due to the variety of models and modifications, finding spare parts is a little difficult.
  • During transportation of a disassembled bike, there is a high probability of curvature of the rotor due to any mechanical impact.
  • Sometimes they interfere with the attachment of the bike rack.
  • Are heavy relative to rim brakes.
  • expensive than rim models.

Hydraulic

Disc hydraulic bicycle brakes have the same benefits as mechanical ones, plus a few of their own:

  • Most powerful braking force of all types.
  • Excellent control of braking force.
  • Work in all weather conditions.
  • Easy movement of the brake lever.

Disadvantages of hydraulic brakes:

  • Hydraulic line repair is quite problematic.
  • If the rotor is bent, it is difficult to align.
  • The highest price relative to other types.

In addition, hydraulic disc brakes have the same disadvantages as mechanical ones.

How to adjust the handbrake on a bicycle. Self-adjusting the brakes on the bike

Cycling is an incomparable pleasure. A constant wind in your hair, a feeling of complete freedom and independence, besides, cycling can replace constant trips to the gym, it’s no secret that riding a “two-wheeled” affects absolutely all muscle groups. First of all, legs, back, arms, abs. all this is maintained in an active tone thanks to cycling. The benefits of a bicycle cannot be understated. But in order to enjoy walks day after day, you need to take care of your “horse”. Preventive maintenance includes brake adjustment.

Security issue

Safety comes first! Yes, this rule is worth remembering every time you want to ride a bike. After all, many “ordinary” walks end with injuries.

Defective brakes

Bad brakes are every cyclist’s problem. I don’t really want to carry out checks before each trip. It is tedious and time consuming. But here’s the problem. it’s necessary. A routine brake check can save lives and health. Adjusting the brakes on a bicycle is a painstaking task. Therefore, it is so important to be able to do it right.

Varieties and models of bicycle brakes

Brake adjustments on a bicycle can vary. In each situation, it is worth looking at the type of braking system. Most often, cheap bicycles are equipped with mechanical rim brakes, or, as they are also called, V-brakes.

Disc mechanical brakes

Everything is on the rise. And as you might guess, disc brakes are second in the list of systems of this type. What kind of changes can you see here? All the same levers, the same metal cables. Only the brake itself has been changed. The disc is now bolted to the bicycle wheel. Nearby are two clamps with pads. Yes, the disc wheel is in direct contact with the clamps.

This innovation increases grip. Now, if you hold down the lever, the wheel will not spin. This is why disc brakes are used on sport bikes. With it, the braking distance is halved. And this is what needs to be achieved. Adjusting disc brakes on a bicycle is different from the technique of adjusting rim brakes. So it can be tricky to ride V-breaks all your life and then switch to disc brakes. After all, you will have to learn to configure this system again.

Disc hydraulic brake

So, the winner of the rating. It is hydraulics that rules the world of brakes. How does this system work? There are handles, there is a disc and there are braking elements. They are connected together by rubber tubes, inside of which there is oil, or, as it should be correctly said, brake fluid. What are its pros and cons? The hydraulics are responsive to every pressure. It can be said to instantly transmit pressure. That is why many athletes and extreme sportsmen use hydraulic disc brakes on their bikes. After all, the accurate transmission of sensations helps to win important seconds. The hydraulic brake firmly compresses the metal disc so that, when pressed hard, the rider can literally fly out of the saddle. But, like everyone else, hydraulics have their negative sides.

First, the high cost. This, of course, is a dubious minus, because this system is bought not by ordinary amateurs, but by professionals. Second, the fix issue. Yes, the hydraulics simply cannot be fixed by yourself. The slightest upset. and a trip to the workshop is guaranteed. And again, repairs will cost a pretty penny. Parts of the system, such as tubes, are not very reliable. If this part bursts, brake fluid will escape. Therefore, you can only brake with your feet. Adjusting hydraulic brakes on a bicycle is tricky. This, if possible, it is better to entrust the master.

First steps in repair and adjustment business

As always, start simple first. In this case, from the repair of the simplest brake system. rim. V-breaks are not famous for their ingenuity. A simple device as two and two. What does this mechanical brake system consist of? There are levers that are mounted on the steering wheel. There are tubes (it is correct to call them “shirts”), inside of which an iron cable fidgets. Two clips and pads. Everything is nothing more. That is why there are only three positions on which to regulate the V-break.

Adjusting the rear brakes on a bicycle

In theoretical terms, everything is clear. Three parameters, three actions, and only one result. well-tuned brakes. Once again. this is in theory. In fact, it is difficult for beginners to do everything perfectly. Adjusting the rim brakes on a bicycle is a delicate thing. So you have to be patient first.

So the first step is to adjust the pads. They should be parallel to the rim on both the rear wheel and the front.

Especially do not tolerate the striking of this element on the tire. A couple of kilometers. and the rubber will be frayed to holes. It is undesirable for the block to also go beyond the boundaries of the wheel. From this, it is quickly erased, but the desired effect (good inhibition) is not. Therefore, it is so important to correctly adjust the position of the brake pads. Adjusting a mechanical brake on a bicycle begins with the selection of tools. You will need: a hexagon, a screwdriver and a 12 key. For rubber clamps, you should take only a hexagon. It is worth starting by holding the brake lever. This will push the pads against the rim. Having examined the situation, you can immediately see where something is wrong. Use this tool to loosen the washer. Then, while still holding the brake lever, align the rubber clamp in the desired direction. The same is worth repeating on the other side. This is just the first step towards a perfectly tuned brake.

Adjusting the front brake on a bicycle

The hardest part lies ahead. Do not be afraid, you just need to concentrate. So, you need to adjust the distance between the pads and the wheel. It is important. Again, action monitoring is similar for the front and rear brakes. It is worth remembering that if the distance is too large, the clamps will not fit well. Therefore, there will be no inhibitory effect. If, on the contrary, you leave little room for the brakes, they will strike the rim. This will quickly wear off the pads, and the wheel will constantly brake. In general, you can adjust the distance between the pads and the rim using one nut, which is located on the levers, on top, where the metal cable is attached.

It should be unscrewed, thereby loosening the grip. From this action, the levers will part, do not be afraid. With the force of your hand, you need to lean against the rim. Then squeeze the brake lever so that it does not reach the steering wheel for a couple of centimeters. Keeping the levers in the same position, screw the nut back. Adjusting the brakes on a bike doesn’t stop there.

Spring tension

The springs that are part of the mechanical rim brake system are also responsible for the distance between the wheel and the block. But, unlike a nut with a cable, they allow you to adjust the distance down to a millimeter. That is, more precisely. The spring tension can be changed with a single bolt that is screwed on and off every now and then. This bolt is located on both sides of the brake. Therefore, when a situation arises that one side touches the rim, and the other is separated, you just have to tuck the bolt. and everything will fall into place. When this element is twisted, the spring becomes “harder”. Consequently, the distance will increase. If you unscrew the bolt, the spring will weaken. From this the distance will decrease. So, by adjusting each element, you can achieve perfect accuracy.

Disc brakes

Bicycle disc brakes can be adjusted with just two screws. The first is responsible for the distance between the disc and the pad. The second is responsible for its location in the vertical plane. Therefore, if the rubber clamps are constantly touching the brake or, on the contrary, the disc has left the “contact zone” of the pads, you just have to work hard with a screwdriver. Through trial and error, you can understand what is responsible for what, and then it’s a matter of technology. By tightening the screw, you can immediately adjust the position.

Hydraulic disc brake

Adjusting the brakes on a hydraulically equipped bicycle is difficult. To do this, you need to have special tools and special skills. But you can do everything to prevent breakdowns. Prevention will help the hydraulics not break down and serve the owner for a long time.

How to set up rim brakes on a bicycle

The braking system is one of the most important technical components of a bicycle. The safety of both the cyclist and other road users directly depends on its condition. Good brakes are essential in any situation, from riding in parks to strong cycling.

In the modern classical sense, a bicycle brake is a pressure mechanism that acts on the wheel rim. There are actually several types of brakes, however v-brake (rim) is the most common option on bicycles of various classes.

Braking system characteristics

The following terms are used to qualitatively describe the operation of rim brakes:

  • impact force;
  • efficiency;
  • wear resistance;
  • modulation;
  • service requirements;
  • comparative features.

Force of impact, or braking, is a parameter that shows how much the brake can clamp the rim so that the bike cannot be moved. Maximum effort is required only to stop completely and lock in place. On the road, the effort is not fully used to adjust the speed. The range of action on the wheel rim by pressing the handle is called modulation, or accuracy, of the brakes.

An active cyclist uses his transport not only in dry and cloudless weather. Rain, mud, sand. everyone who rolls out their bike on long trips will have to face this. The effectiveness of brakes allows you to describe their behavior in a wide variety of conditions.

Durability is a measure of durability, taking into account the prescriptions for using the bicycle as a whole. Timely maintenance can increase the service life of the braking system. Service Requirements describe how to properly install and adjust the mechanism, how often to do this, and guidance on how to replace parts.

Varieties of rim brakes

Rim brakes are divided into several types:

  • tick-borne;
  • cantilevers;
  • V-brake (vector mechanical);
  • hydraulically driven.

Caliper brakes. previously popular modifications, are now rare on the market. They are a classic model of rim brakes that are attached to the fork or stays of the bicycle frame. Design features and operating principle:

  • Consist of a handle, a drive cable, two movable bows and brake pads.
  • The handle is attached to the handlebars of the bicycle, a cable is pulled from it and fixed on the clamping side of the arches. The body itself is attached strictly above the wheel, pads are screwed to the lower arches.
  • Through the cable, the force is directly transmitted to the clamping part of the arcs, due to which they are compressed, and the pads are in contact with the rim.
  • Responsible for the release is an elastic metal insert or spring built between the levers.

The levers have a single axis of rotation and move towards each other like pliers pincers. Hence the name. tick-borne. Advantages. ease of installation, simple setup. Cons. weak braking force, low modulation, high abrasion of the pads, require frequent debugging. Fits on road racing bikes and optionally as a front rim brake on road models.

Cantilevers belong to the second type of disappearing brakes. The principle of their operation is to extend the levers under the action of a stretched leash. Cantilever brake working principle:

  • Through the main cable, the force is transmitted to the jumper.
  • The cable pulls the jumper up, the leash attached to it is pulled.
  • The leash connects both levers, which are rigidly attached to the frame.
  • Due to the convergence of the levers, the pads approach the rim.

The cantilevers are dirt resistant, will not bump the tire and are easy to install. Significant disadvantages include:

  • decrease in braking force as the leash is pulled;
  • you need to create a high effort to stop the bike completely;
  • difficulty of adjustment.

To justify the latter, it is worth noting that the position of the pads can be adjusted within wide limits.

V-brake is a common type of rim brake on high-speed bicycles. Compared to cantilevers, it has a higher precision and longer shoe longevity. They are also easy to remove and repair yourself.

The vectors are partially similar in design to cantilevers: the front brake levers are bolted to the fork, the rear brake levers are attached to the upper stays. The legs are tied together with a pulling cable. The drive cable is brought to one side, but due to the straight form of the “tie” forces are equally transmitted to both levers.

Hydraulic bicycle rim brakes are a more advanced mechanical model. The drive system consists of a control cylinder, a hydraulic line and power cylinders. The forces from the handle are transmitted to the master cylinder, which, through the oil, acts on the power cylinders. Those, in turn, shift the pads towards each other.

Advantages. high compression force and efficiency, excellent modulation. Disadvantages. deterioration of performance when the hydraulic line is clogged, difficult repairs. Used a similar type of brakes for freeride and trial.

Rim-type brakes have low brake pad travel, which means they wear less during operation. A significant disadvantage of this approach is the inability to be used on wheels even with minor rim curvatures. Sensitive brakes will rub against the wheel on the fly, causing reduced speed and increased pad wear.

How to install and configure V-brake yourself

Installing the brake from scratch:

  • Attach the levers to the bike frame.
  • Insert the drive cable into the brake lever.
  • Install the handle on the steering wheel, insert the cable into the grooves on the frame (if any).
  • Connect the cable to the levers and put the spring.

After installation, you will definitely need to adjust the brakes.

The accuracy of the mechanism largely depends on its settings. So, even an expensive system will not work well without proper adjustment, and conversely, a mid-range V-brake can outperform a disc brake in efficiency. What needs to be done to adjust the brakes?

Adjust the cable tension. After adjusting, the brake should instantly respond to squeezing the handle and rebound when it is released. If the pads do not move away from the rims, this indicates insufficient tension. On a tight cable, the handle will be hard to press, and the sheath may burst.

The tension is adjusted with a bolt on the side of the levers. The setup looks like this:

  • Reset Springs.
  • Loosen the cable fixing bolt.
  • Adjust the tension so that in the fully clamped position the distance from the handle to the handlebars corresponds to the thickness of the finger.

If damage was noticed on the cable sheath, it is recommended to immediately install a new set.

Clearance adjustment. The optimal distance is 2. 3 mm from the edge of the pad to the rim. Determination of brake pad wear: cannot be used when the diverter grooves are completely erased (the whole surface is flat).

How do I fit new pads? The location relative to the rim affects the size of the contact area of ​​the pads with it, the braking force and the life of the material. For brake pads with soft rubber surfaces, install them with the leading edge closer to the rim. Brake pads made of hard material are placed strictly parallel to the wheel rotation surface.

If your bike has cartridge pads, you only need to change the pads. Their position is set with a cotter pin; before removing the old surface, it is removed from the body. Similarly, in the reverse order, insert a new pad and fix it with a cotter pin.

Adjustment of the position and displacement of the shoe housings are carried out by means of a bolt and washers. For accurate fixation, you need to squeeze the brake and set the position of the pads strictly on the surface of the rim.

The last step will be to test the operation of the system in practice, that is, in real driving conditions. As a rule, the V-brake setting is obtained immediately. However, if braking is delayed or the handle does not fully return to its original position, the brakes must be readjusted.

How to check and adjust the brakes on a bicycle, useful tips

Every year the number of lovers of riding two-wheeled vehicles only grows. The serviceability and durability of structures depends on the quality of service. The question of how to adjust the brakes on a bicycle arises quite rarely, but requires a timely decision. A properly functioning system ensures a comfortable, safe ride.

Types of brakes

The choice of suitable bicycle brakes depends on the mode of operation and financial capabilities. So, discs are considered the most expensive, v-brake is a more economical option. The hydraulics and rim system do their job well too. Each variety has its own advantages and disadvantages.

Take the survey. Disk

The disc mechanism was originally the preserve of cars and motorcycles. Over time, this system migrated to the cycling world. It consists of a brake disc, a wheel attached to the hub and a caliper, inside which the pads are located. The most common element sizes: 140, 160, 180, 185, 203, 220 mm. The larger the rotor diameter, the more efficient the whole structure will be.

Bicycle disc brakes can be mechanical or hydraulic. The advantages of the mechanism include:

  • powerful, fast braking;
  • efficiency of work in any conditions;
  • the ability to install on wide tires;
  • durability of pads;
  • the mechanism does not affect the wear of the rim.

Among the shortcomings, complex repairs in the field are noted in the absence of a special tool. In addition, the disc system is heavy and expensive.

Mechanical Hydraulic

V-brake

When installing the mechanism, the brake cable is led from the side to the upper part of the lever. The latter compresses both parts of the element with cartridge pads. Parallel pressing ensures fast braking. The advantages of the system include:

  • simplicity and efficiency of the design;
  • low weight compared to drum and disc mechanisms;
  • affordable cost.

Among the disadvantages of v-brakes, a decrease in the result is noted when dirt or water gets on the rim. Due to the increased friction against dust particles, the sand mechanism wears out faster. Another disadvantage is that it is impossible to install such a system on a bicycle with wide wheels.

Hydraulic

The principle of operation of hydraulic brakes is the same as for rim and disc brakes. The only difference is that the element is not driven by cables, but by a special hydraulic line that connects the mechanism to the brake levers. The advantages of the design include:

  • the most powerful braking in contrast to other types;
  • high level of braking force control;
  • effective functioning in all weather conditions;
  • the ability to use with wide wheels;
  • the mechanism does not affect the wear of the rim.

Among the disadvantages of a hydraulic brake for a bicycle, the complexity of repair, finding suitable parts, straightening a bent rotor is noted. The mechanism is heavy and expensive.

Rim

This mechanism is currently the most popular. It acts directly on the surface of the rims, stopping their rotation. The drive levers are located on the steering wheel, the pressure elements are located in the immediate vicinity of the wheels. All parts are connected using cables.

There are several types of mechanism: tick-borne, cantilever, v-brake. The advantages of rim brakes include:

  • simplicity of design;
  • maintainability both at home and on trips;
  • high braking efficiency;
  • versatility;
  • light weight.

Rim brakes are not without their drawbacks. The products are characterized by low modulation and sensitivity to rim curvature. Moisture and dirt impair the operation of the mechanism, with prolonged use, the structure heats up, which leads to abrasion of the pads.

Tick-borne Cantilever V-brake Circuit

Checking the performance of the brake system

You can determine the condition of the brakes on a bicycle by visual inspection or observations while riding. The most common mechanism problems include:

  • Specific sounds. It can be periodic tapping, hum at speed, creak or whistle. Such signs indicate a malfunction of the pads or mechanical elements.
  • Poor response to effort. If the brakes do not work well, do not immediately slow down the rim, this is a sign of a problem with hydraulics or cables.
  • Mechanical damage to cables, mechanism parts. Typically, such breakdowns can be detected by visual inspection.

After purchasing a new bike, it is mandatory to run in and adjust the brakes, which is performed several times after riding. If the bike has not been used for several months, especially in the cold season, the pads and mechanisms need full service.

A superficial inspection of bicycle brakes should be done before every ride. Make sure that all elements are clean and in place. For moderate use, it is recommended to be checked by a qualified technician every six months. There are a number of problems that an inexperienced person cannot notice and eliminate in time. With intensive use, you will have to carry out diagnostics more often. once every 2-4 months.

For people who are faced with the problem of setting up the system for the first time, it is better to resort to the help of a wizard who will tell you how to properly adjust the brakes on a bicycle.

What tools will be needed during adjustment and installation

Taking care of the braking system is the primary responsibility of every cyclist. The convenience of riding, the safety of the athlete and the people around him depends on the state of the mechanisms. Full maintenance of the structure is impossible without special tools:

  • screwdrivers. Phillips and flat-head screws are required;
  • a set of wrenches or special bicycle accessories;
  • hexagons;
  • wedge gasket. serves to adjust the gap, it is relevant in the presence of soft type brake pads without metal elements;
  • nippers;
  • bike caliper, adapters, pads, lever;
  • cables;
  • rotor, set of hardware;
  • clamps for fixing the cable to the frame.

Special bike kits are ideal for installing and adjusting the brake mechanism. If they are not there, you will have to select tools separately. Before starting work, you need to find a suitable free space, put the bike in a comfortable position, prepare everything you need, lay it out next to it. In such conditions, installation and configuration will take much less time.

How to install on a bike yourself

Installing a brake system on a bicycle is not difficult for men who are tech-savvy. The work consists of several stages:

  • remove all attachments from the bike, including wheels;
  • the brake levers are securely fixed, the caliper must be tightened with hexagons, the hydraulic line with clamps;
  • wheels and all other parts of the structure are installed in their original places.

The rear, front and manual mechanisms are subject to adjustment. Adjusting the v-brake system involves changing the cable tension, as well as the geometry of the pads attachment. Rim brakes are very easy to adjust due to their open design. In most cases, the process consists of replacing damaged items.

Disk systems are rarely adjusted. It means checking the condition of the handle, transmission, pad. If the rotor is damaged, there are chips, cracks on its surface, it is pointless to adjust the mechanism, you will have to replace it.

Hydraulic brakes are popular with professional athletes. The adjustment process will be the same as for mechanical ones. The only difference is the work with brake fluid, which must be vented in cold weather to improve the pad travel.

Mechanical types of brake systems sometimes need to adjust the angle of pressing the pads. The element must be parallel to the rotor. This will help increase the life of the mechanism.

Features of adjustment on children’s models

Children’s bicycles are always equipped with a foot brake, which is activated when pedaling in the opposite direction. Such a device is considered the safest and easiest to use in comparison with manual counterparts. The mechanism is located in the rear hub, there are pads inside.

The same systems are installed on teenage bicycles as on adult models. Most often these are rim or disc brakes.

The foot brake or drum brake is durable, wear-resistant, however, it must be inspected and adjusted regularly. To check if the mechanism is working properly, pull the pedals in the opposite direction. If the system is fully operational, the brake is applied after a quarter of a wheel turn. If this does not happen, the structure is not functioning properly. The element is located in a closed sleeve, therefore it is not recommended to repair it yourself.

The braking system is one of the most important technical components of a bicycle. There are different types of mechanisms, each of them has its own advantages and disadvantages. Parts are not adjusted too often, if you have the appropriate skills, you can do the work yourself.

Video. Adjusting the brakes on a bicycle

Adjusting the brakes on a bicycle should be carried out regularly. such maintenance will guarantee the safe operation of the vehicle. There are two main types of brakes on modern bicycles. rim and disc brakes, but disc brakes can be mechanical or hydraulic. The type of brake system installed on a particular bike will determine the process of their maintenance.

How to check and adjust the brakes

There are clear instructions for checking and adjusting the brake system of a bicycle. If you adhere to it, then the whole process will take little time and will be effective.

Procedure for checking and adjusting the brake system of a bicycle:

  • Dry brake test. It is necessary to raise the front wheel and, having unwound it, press the left brake lever. If the wheel comes to a sudden stop during this test, the braking system is in order and no maintenance is required. It is worth considering one nuance. if the brake lever touches the steering wheel, then you just need to pull the cable. The operation of the rear wheel brake system is checked in the same manner. To tension the cable, you need to use curly bolts. just tighten them a little and, if only minor adjustments are required, this will correct the situation. It often happens that such a minimum adjustment does not work. in this case, we look where the end of the cable is on the bike (it is always longer than necessary in advance), unscrew the bolt that holds it. It remains only to tighten part of the cable with pliers and tighten the bolt, applying the possible force.
  • Checking the brake pads. After the brake levers have been tested, the condition of the brake pads should be carefully examined. However, the order of action can be changed. first work with the pads, and then with the handles.

The brake system setting is different for rim and disc types, since different rotating mechanisms and pads are used.

Adjusting the rim brakes

Mountain bikes use a v-brake braking system. using this as an example, we will consider the principles of tuning, since it is also available on other bicycles with rim brakes. The difference can only consist in a different arrangement of bolts and screws that will need to be tightened / tightened.

Note: it is important to observe three main rules:

  • the pads should be parallel to the rim;
  • the gap between the rim and the block should not be more or less than 1 mm;
  • the pads should be symmetrical in relation to each other.

How to achieve these guidelines when adjusting rim brakes on a bicycle:

  • You need to find a hex nut. it fixes the pads. To loosen it and set the brake pads in the desired position, you will need to press the brake lever and watch how the shoe touches the rim. By releasing the brake lever, the shoe can be set to the desired position. it moves up, down and at an angle.
  • The distance between the shoe and the rim of the wheel should not be more than 1 mm, although in some models of bicycles there are also 2-3 mm. exact information about a specific vehicle can be obtained either from the instructions for it or on the Internet for technical characteristics. It should be noted that braking of the wheel should occur even with the minimum pressing of the brake lever. That is, if the wheel stops only when the brake lever is fully pressed “all the way”, then this is incorrect.

After carrying out all the specified work, it is imperative to check the operation of the brake system. First, this is done at idle speed. lift the front wheel up, spin it up and press the handle sharply, then do the same with the rear wheel. The next step is to check the operation of the brake system “in action”. get on the bike and ride 3-5 meters, braking sharply. If the bike has stopped even with a minimal pressure on the brake lever, then the system has been serviced correctly.

Setting up disc brakes

As a rule, adjustment of disc brakes consists in periodically tightening the cable. But often you have to replace the pads, however, on disc brakes they wear out longer than on rim brakes. First you need to find out which specific disc brakes are installed on the bike. brake pad adjustments for hydraulic and mechanical systems will differ.

Experts recommend taking note of the following points:

  • If there are hydraulic disc brakes on the bike, then replacing the pads may not be necessary. they are able to do it on their own. But one caveat should be taken into account. if the hydraulic system is closed, then you will have to adjust the pads in manual mode. for this, special valves are provided.
  • If you have to adjust disc mechanical brakes, then you will need to pull the cable according to the above instructions and check the location of the pads. the distance between them and the disc should be within 0.2-0.4 mm.
  • In order to adjust the pads with disc mechanical brakes, you need to use special bolts. by tightening them, you can see how the pad moves. You need to be especially careful when setting the distance between the pad and the disc. 0.3 mm is too small, it’s easy to make a mistake.

Be sure to check the operation of the brake system in action after the work is done. ride your bike for a few meters and try to brake. If the cable is too tight, or the pads are too close to the disc, then too sharp braking will occur. this is a “surprise” in which the cyclist begins to move forward, but without his vehicle. Therefore, when driving for a test, you need to be extremely careful and careful, if necessary, the disc brake system is adjusted again taking into account previous errors.

How to adjust the brakes on your bike yourself?

The question of how to adjust the brakes on a bicycle is very rarely posed to the owners of modern bicycle bikes, since the quality of modern braking systems is so high that the settings installed at the factory during the production process do not go astray for years. However, in any case, the cyclist needs to know the intricacies of their settings and carry out preventive maintenance at least once a season. This will allow you to extend the life of your bike and protect you from possible accidents that may happen to you on the road.

Types of bicycle brakes

In order to know how to properly adjust the brakes on a bicycle, you need to be able to understand their design. Today, modern bicycles are equipped with the following types of brakes: rim, drum and disc brakes. over, each type of brake systems is subdivided into subspecies.

Types of bicycle brakes

Rim systems are:

  • tick-borne;
  • cantilever;
  • hydraulic;
  • V-brake type.

Drum-type brakes do not have subspecies, but disc brakes have the following varieties:

  • hydraulic;
  • mechanical;
  • hybrid.

Rim brakes are those braking systems in which the wheels of the bicycle are braked by clamping the wheel rim. As a result, the rotation speed is reduced until the vehicle comes to a complete stop. Rim braking systems are among the most common due to their simplicity and low cost. They are used on almost all types of bike.

Bicycle Hydraulic Brake Device

Drum brakes, or roller brakes, are very similar in principle to those used on cars. Here, the braking elements of the structure are placed inside the wheels, and they stop their movement by pressing against the rotating part of the wheel. Since brakes of this type have a large mass and are rarely repairable in field conditions, they do not have sufficient strength, they are usually used on recreational cycle bikes.

As for the disc brakes, they are the most common today and they are installed both on cars for beginners and on professional bikes. Their device consists of a disc securely attached to the hub of the wheel, as well as to the frame or caliper fork, hydraulic tube or cable. The task of the latter is to transfer the force created by the cyclist’s brush when braking to the caliper. This braking system does not need constant tuning, is not afraid of precipitation and cold weather, has a long period of operation.

Bicycle disc brake device

To know how to set the brakes on a bicycle correctly, you will need to carefully study the design of all types of braking systems. At the same time, some types of bicycles are equipped with rather complex braking systems, and therefore the bicycle owner, in order to have an idea, for example, how to adjust the hydraulic brakes on a bicycle, will need to carefully study the instructions for it. It is worth reading the materials on this topic located on specialized sites dedicated to cycling.

The main symptoms of bicycle brake malfunctions

If you have studied the information on how to adjust the brakes on a bicycle, you should also additionally understand the signs indicating a breakdown of its brake system.

Adjustment of the brake systems of bicycles is carried out when you have purchased a new bike, as well as after the expiration of its running-in period

These include:

  • The appearance of unusual sounds during movement, namely knocks, whistles, creaks. This indicates that the car has problems with the pads or with the brake itself.
  • Poor response of bicycle brakes to the force applied by the cyclist to the brake lever. In this case, you can diagnose a malfunction of the hydraulic system or the bicycle brake cable.
  • The presence of visually detectable mechanical damage, namely impact marks after a fall. In this case, the brakes will work, but they will have to be additionally adjusted.

This procedure will need to be carried out even when you have not used the car for more than a month, especially in the cold season.

During brake adjustment, preventive maintenance of other systems and mechanisms of the bike is carried out

In order to understand how to adjust the brakes on a bicycle, you need to know the basic operations that are performed while doing this. Usually, all types of brake adjustments require the following operations:

  • Selecting the best way to position the pads in relation to the wheel rim, or adjusting the disc or drum in the same way.
  • Debugging their work planes.
  • Selection of the optimal force on the working bodies located on the steering wheel. Usually this is a brake handle, with the help of which force is transmitted to the working elements of the brake system. This force to the rear brake can be transmitted through the bicycle pedals.

When adjusting the brakes, preventive maintenance of other systems and mechanisms of the bike is carried out, for example, it will be imperative to check the correct geometry of the wheel rim. If you identify the presence of an eight on it, it will need to be corrected so that the last does not erase the rim.

When setting up your brakes, always remember that knowing how to adjust the rear brakes on a bicycle is far from the same as knowing how to adjust the front brakes on a bicycle. Usually, the braking systems located in front and behind the bike are quite different from each other, so you need to have a different approach to them.

Adjusting rim brakes

You can learn how to set up rim brakes on a bicycle by carefully studying the instructions for their design. In addition, information on this topic can be found in abundance on cycling websites. Usually, the process of adjusting the rim brakes does not cause absolutely any problems, even for a novice bike rider. The fact is that the main operation for servicing the brakes of such a system is to replace the brake pads, so all the subtleties here will consist in the correct operation of the mechanisms holding them.

Setting up the rim brakes on your bike

It should be noted that in general most modern bicycles use a type of brake pad mount such as the V-Brake. It is characterized by the presence of separate levers in their design, made in the form of the letter V. They are connected by a cable held by a jacket. It is about the maintenance of this type of brake system that we will tell.

In order to carry out maintenance of the rim brake, you must:

  • Open the brake, and using force remove the cable jacket from the mount.
  • Unscrew the screw securing it to the frame.
  • Remove the brake mechanism.
  • To work with pads, unscrew the pads fixing screw.

When doing this, be careful not to forget the correct sequence for installing the washers. The fact is that they are mounted in pairs. concave and convex. The correct adjustment of the entire brake system depends on how correctly they are installed.

Finished brake cartridges must match the brakes of the bike exactly

Since the most common operation is brake pad replacement, let’s take a look at it. To do this, you will need to perform all the operations listed above and pry on the old block to remove it. A new one is installed in the vacant place. When performing this work, you must be careful, since you will have to adjust the brake shoe in place.

In addition to replacing the brake pads, they are adjusted on the spot, and the level of the cable tension is also controlled. For this, the screw located on the brake lever is tightened to the desired state. As a result of this clockwise rotation, the brake pads move away from each other.

In addition, the tilt of the brake shoe is also adjusted by loosening the fixing screw. If you recently purchased a bike and it is difficult for you to follow the procedures described on your own, then in order to learn how to adjust the brakes on a bike, you should watch a video on this topic.

If new pads are installed on the bike, then the main thing is to put on spacers and washers in the correct sequence

Disc brake adjustment

Since disc brakes are rarely used on modern bicycles, you will only need to adjust them when you need to learn how to adjust the brakes on a mountain bike, that is, when you start cycling at least semi-professionally. At the same time, there are many types of brake disc systems, but we will consider maintenance work with rotary brakes.

Before proceeding directly to the process of adjusting the brake system of a bicycle, you will need, if you do not have experience with such work, study the materials on how to adjust disc brakes on a bicycle, and watch about this video. In addition, before adjusting disc brakes, you must:

  • Check the position of the brake lever.
  • Inspect the disc or rotor for mechanical damage. If it has chips and dents, it will need to be replaced.
  • Check the condition of the brake cable and the pads located in the brake shoe.

Adjusting bicycle disc brakes

To do this, it will have to be installed strictly parallel to the disc or rotor. If you install a block crookedly, this will greatly shorten its service life.

The disc brakes themselves are adjusted directly on the caliper according to the following scheme:

  • We fix the wheel exactly in the position in which it will be while driving. This is very important for determining the location of the rotor and hub.
  • We slightly loosen the fastening of the caliper so that it does not fall, but at the same time it can move.
  • Clamp the brake lever to install the caliper in place.
  • Moving the brake machine or tightening the bolts.
  • Working with the bolts one by one, we finally put the car in place.

Adjusting the brake levers

In addition to performing the adjustment procedure, disc brakes require periodic rotor dressing. A simple adjustable wrench is usually used to repair minor damage to this assembly. In the event that it is badly damaged, it makes sense to replace it.

When adjusting disc brakes, try not to touch them with your hands, as they are very bad for getting fat into the system, even from your hands. Therefore, before starting work, it is necessary to carry out the procedure for degreasing them with gasoline.

After learning the process of how to set up disc brakes on a bicycle, you can then make repairs in any conditions, for example, when you are on a hike or on a country road.

Adjusting the bike’s hydraulic brakes and replacing the pads

The principle of operation of hydraulic brakes on a bicycle is to transfer pressure through the hydraulic line from the brake master cylinder to the brake cylinder in the caliper, which in turn moves the pads. The brake fluid is not compressed, therefore such a system is more reliable and efficient than a mechanical one.

On the other hand, the hydraulic lines and the entire braking system require careful attention and constant maintenance, and therefore repairing and adjusting hydraulic brakes often seems to be a difficult task.

How to adjust everything yourself

Adjusting the hydraulic brakes may be necessary if you notice extraneous sounds while driving. squeaking or rustling. A simple test will help to make sure that the adjustment is necessary: ​​lift the bicycle wheel and spin it. If the pads touch the brake disc, the wheel will quickly stop spinning.

The relative position of the pads and the rotor must be very accurate, because this affects the brake performance. To check the position of the disc in the typewriter and the position of the pads, place a white sheet under them and, if necessary, direct a bright light on it. against such a background it is easier to notice deviations.

Adjust the hydraulic brake as follows: 1. Loosen the caliper mounting bolts as much as possible so that it can move freely to the sides.

Squeeze the brake lever so that the pads are fully pressed against the rotor.

Check the position of the pad valves. they should be symmetrical, at the same distance from the rotor. Move the caliper slightly to the left or right if necessary.

Without releasing the brake lever, tighten the caliper mounting bolts.

Release the handle and check the brakes. Ideally, the pads should be at a minimum distance from the brake disc, but not touching it.

If you notice that one pad is located closer to the disc than the other, but the rotor itself is perfectly centered in the machine, do the following (preferably two people): press the disc against the more protruding pad and apply a little brake. Due to the fact that one valve works more than the other, they will align and the problem will be eliminated.

The final touch is to set the position of the brake lever relative to the steering wheel. Sitting in the saddle, check if you feel comfortable using the brake lever and if you can quickly press it in an emergency. If the knob is too far for you, tighten the adjusting hex a little more. this will bring the knob closer, but at the same time the pads will move closer to the rotor. The main thing here is not to overdo it and not make the stroke of the pads too small.

Video demonstrating the entire adjustment process:

Replacing brake pads

Poor operation of hydraulic disc brakes can be due to the following reasons:

  • damage or contamination of the hydraulic line or ingress of air into it;
  • complete abrasion of the brake pads;
  • dirty pads or disc.

In the first case, replacement of the hydraulic line or bleeding of the hydraulic brake is required, with the second and third cases it is easier to understand.

First, take a close look at the brake pads. All manufacturers prescribe their minimum thickness, at which the braking performance does not decrease. By the way, uneven wear of the left and right pads indicates that the rotor is not centered relative to the caliper.

As the pads wear out, the valves move closer to the rotor, so before installing new pads, you should slightly push them apart and re-adjust their position. The entire replacement procedure consists of the following sequence of steps: 1. Place the bike on a repair stand and remove the wheel.

Remove the retaining ring and unscrew the fixing bolt.

Pull out the old pads away from the hub axle. Remember the location of the return spring between the pads. it releases them after the end of braking.

Thoroughly clean the valve surfaces and the inside of the caliper. Use a lint-free technical cloth and a mild cleaner such as isopropyl alcohol.

Using a plastic lever, such as a tube changer, press both valves into the caliper. To install the valve correctly, you need to press on its center, not on the edge.

Install a return spring between the new pads and insert them into the machine.

Tighten the fixing bolt and install the retaining ring.

Clean the brake disc and replace the wheel. Check the correct position of the rotor, pads and the functionality of the entire system.

it should be said that all work should be done with clean hands. Also, to keep the brakes less dirty, you should close them when lubricating the chain. With a comprehensive bicycle service, the brake system is repaired last.

Adjusting the brakes on bike pads

Timely brake adjustments can help keep you out of trouble

There are two types of brakes on modern bicycles. rim and disc. The braking system used on your bike will determine how you adjust the brakes on your bike. As a rule, the brake does not require frequent adjustment, but there are times when its adjustment is simply necessary. After all, a reliable brake is the key to your safety.

often than not, adjusting the brakes on a bicycle means http: //bike-repair-moscow/bike-prepare-season/ that you need to position the brake pads at the required distance from the rim or disc and symmetrically to each other. Also, it may be necessary to tighten the cable or adjust the brake lever.

You can learn even more about bicycle disc brake repair from the article. Setting up and installing hydraulic brakes on a bike is done in a different way, you can learn more about this here. Steps to check and adjust the brakes

  • Determine the type of brakes. disc, rim or other option.

Checking the brakes when idle

Raise the front wheel, spin it up and push the left brake lever. If the wheel has stopped, most likely the brake is working properly. But if at the same time the brake lever touches the steering wheel, then you need to pull the cable. Do the same with the rear wheel.

  • In order to tighten the cable, shaped bolts are provided on the brake lever. Try to twist them. if the cable requires a little adjustment, this should be enough.
  • If this does not help, then you need to tighten the cable. The cable in the brake lever is inserted into a special slot, at its end there is a cylinder of a larger diameter, for which it is held inside the handle. Therefore, it is tightened in the brake itself. See where the end of the cable is on your bike. The cable is obviously longer than the required length, so its end on the side of the brake is always visible. Sometimes it is even wound. We look at which bolt holds your cable, loosen it and tighten the cable with pliers. We tighten the bolt harder to clamp the cable.
  • Checking the brake pads

    If everything is in order with the handles, check the brake pads. (You can check the pads first and then the handles)

    Setting up disc brakes on a bicycle is different from setting up rim brakes because they use different pads and rotating parts. Therefore, we will consider these systems separately.

    Setting v brake rim brakes

    Today, mountain bikes are widely used with v-brakes, so here’s an example of how to adjust the brakes of a bicycle in the case of a rim brake. Setting up other rim brakes is done in the same way. The only difference is that the bolts and screws that need to be tightened may be in other places. And the approach is the same (even in the case of disc brakes).

    So the basic rule is that the pads should be parallel to the rim. The clearance between the shoe and the rim should be 1mm. And both pads must be symmetrical.

    V-Brake brake adjustment on a bicycle video

    A small instruction on how to achieve this.

    • We find the hex nut that fixes the pads, loosen it and set it as needed. To do this, we press the brake, watch how the shoe touches the rim when pressed and, if necessary, move it (after releasing the brake). The block can move both up and down, and at the desired angle, so you have the opportunity to set it in the right way. The main thing is to understand the essence.
    • We adjust the distance of the pad relative to the rim. The distance between the right shoe and the rim and between the left shoe and the rim must be the same. It should be 1-3mm, depending on your bike. In this case, braking should occur even with a minimal push of the handle. That is, it should not be so that you have pressed the handle halfway, and the wheel does not stop yet, and only when fully pressed, braking occurs!
    • And finally, you must definitely check the action of the adjusted brakes in practice. To begin with, you can do this with one wheel raised and then the other. But then be sure to check in real conditions. (Sometimes the wheel slows down in the air, but get behind the wheel, press the handle and drive on!) Therefore, drive 5 meters, press the brake and check all the conditions mentioned above. If when you press the handle 50% (before the steering wheel) the brake is applied, congratulations! You did everything right!

    Successful rides for rim brake owners!

    How to set up disc brakes on a bicycle, set the correct brake pads Adjusting and setting up disc brakes on a bicycle video

    Adjusting disc brakes on a bicycle is done mainly by pulling the brake cable, but not only. Replacing pads on a bicycle is necessary when they are not yet completely erased and, as a rule, disc brake pads take longer to wear than rim ones. The hydraulic brakes are self-adjusting as the pads wear out. But in the case of a closed-type hydraulic brake, they also need to be adjusted. (Usually special valves are provided for this.)

    Adjusting mechanical disc brakes on a bicycle is most often accompanied by tension on the cable to provide reliable braking. The distance between the pad and the disc should be 0.2-0.4 mm. And the pads, as in the case of rim brakes, should be located at the same distance from the disc. Therefore, after you tighten the cable, check the position of the brake pads.

    Special bolts are provided to adjust the position of the pads relative to the brake disc. As you twist them, you can see how your last moves. Set the desired distance from the pad to the disc. Make sure that when the wheel rotates, the pads do not catch the disc. After all, the gap of 0.3 mm is very small, and you need to be careful. And of course, make sure that the clearance you set is sufficient to brake the wheel.

    Adjusting the disc brakes of a bicycle must always be accompanied by a test under real riding conditions. Drive on level ground for a few meters to determine if your brake is working reliably. Do not forget that if before that you hooked the steering wheel with the handle, now everything can change significantly. Be careful and careful! Braking too hard after tuning may come as a surprise!

    Now you can also enjoy going on a long and not only trip on your bike!

    It is more convenient to set up and adjust the brakes if there is a rack (holder) for repair and maintenance of a bicycle How to put disc brakes on a bicycle?

    It often happens that you buy an expensive thing, and then the same thing comes out, only with a new “chip”. It’s the same with a bicycle. you bought a bike for yourself, you ride, you like everything, then you see how more and more often your friends or “random passers-by” appear big with disc brakes. And you wonder. is it possible to install disc brakes on your type of bike? And in general, is it worth it? Let’s try to answer your questions.

    If you have chosen a mechanical disc brake and you already have the correct brake levers and cables installed, then you can leave them. Just make sure that the cables are not loose at the ends. If you haven’t changed the cables for several years, it is better to replace them for new brakes, because dust and dirt gets inside the shirts, which can create friction. Since changing the braking system, so thoroughly. Replace cables and shirts.

    In case your choice fell on smooth hydraulics, you will need to completely remove all brakes, and install new levers and lay the hydraulic lines. Some frames have rails in which the brake lines can be positioned. Don’t rush to throw away the old brake. If you fail to adjust the hydraulics, or some kind of breakdown occurs far from the city, he can save you great.

    You will also learn how the brake pads are adjusted and their selection for v-brake brakes read in the article.

    Self-adjusting the brakes on the bike

    Cycling is an incomparable pleasure. A constant wind in your hair, a feeling of complete freedom and independence, besides, cycling can replace constant trips to the gym, it’s no secret that riding a “two-wheeled” affects absolutely all muscle groups. First of all, legs, back, arms, abs. all this is maintained in an active tone thanks to cycling. The benefits of a bicycle cannot be understated. But in order to enjoy walks day after day, you need to take care of your “horse”. Preventive maintenance includes brake adjustment.

    Security issue

    Safety comes first! Yes, this rule is worth remembering every time you want to ride a bike. After all, many “ordinary” walks end with injuries.

    Defective brakes

    Bad brakes are every cyclist’s problem. I don’t really want to carry out checks before each trip. It is tedious and time consuming. But here’s the problem. it’s necessary. A routine brake check can save lives and health. Adjusting the brakes on a bicycle is a painstaking task. Therefore, it is so important to be able to do it right.

    Varieties and models of bicycle brakes

    Brake adjustments on a bicycle can vary. In each situation, it is worth looking at the type of braking system. Most often, cheap bicycles are equipped with mechanical rim brakes, or, as they are also called, V-brakes.

    Disc mechanical brakes

    Everything is on the rise. And as you might guess, disc brakes are second in the list of systems of this type. What kind of changes can you see here? All the same levers, the same metal cables. Only the brake itself has been changed. The disc is now bolted to the bicycle wheel. Nearby are two clamps with pads. Yes, the disc wheel is in direct contact with the clamps.

    This innovation increases grip. Now, if you hold down the lever, the wheel will not spin. This is why disc brakes are used on sport bikes. With it, the braking distance is halved. And this is what needs to be achieved. Adjusting disc brakes on a bicycle is different from the technique of adjusting rim brakes. So it can be tricky to ride V-breaks all your life and then switch to disc brakes. After all, you will have to learn to configure this system again.

    Disc hydraulic brake

    So, the winner of the rating. It is hydraulics that rules the world of brakes. How does this system work? There are handles, there is a disc and there are braking elements. They are connected together by rubber tubes, inside of which there is oil, or, as it should be correctly said, brake fluid. What are its pros and cons? The hydraulics are responsive to every pressure. It can be said to instantly transmit pressure. That is why many athletes and extreme sportsmen use hydraulic disc brakes on their bikes. After all, the accurate transmission of sensations helps to win important seconds. The hydraulic brake firmly compresses the metal disc so that, when pressed hard, the rider can literally fly out of the saddle. But, like everyone else, hydraulics have their negative sides.

    First, the high cost. This, of course, is a dubious minus, because this system is bought not by ordinary amateurs, but by professionals. Second, the fix issue. Yes, the hydraulics simply cannot be fixed by yourself. The slightest upset. and a trip to the workshop is assured. And again, repairs will cost a pretty penny. Parts of the system, such as tubes, are not very reliable. If this part bursts, brake fluid will escape. Therefore, you can only brake with your feet. Adjusting hydraulic brakes on a bicycle is tricky. This, if possible, it is better to entrust the master.

    First steps in repair and adjustment business

    As always, start simple first. In this case. from the repair of the simplest brake system. rim. V-breaks are not famous for their ingenuity. A simple device as two and two. What does this mechanical brake system consist of? There are levers that are mounted on the steering wheel. There are tubes (it is correct to call them “shirts”), inside of which an iron cable fidgets. Two clips and pads. Everything is nothing more. That is why there are only three positions on which to regulate the V-break.

    Adjusting the rear brakes on a bicycle

    In theoretical terms, everything is clear. Three parameters, three actions, and only one result. well-tuned brakes. Once again. this is in theory. In fact, it is difficult for beginners to do everything perfectly. Adjusting the rim brakes on a bicycle is a delicate thing. So you have to be patient first.

    So the first step is to adjust the pads. They should be parallel to the rim on both the rear wheel and the front.

    Especially do not tolerate the striking of this element on the tire. A couple of kilometers. and the rubber will fray to holes. It is undesirable for the block to also go beyond the boundaries of the wheel. From this, it is quickly erased, but the desired effect (good inhibition) is not. Therefore, it is so important to correctly adjust the position of the brake pads. Adjusting a mechanical brake on a bicycle begins with the selection of tools. You will need: a hexagon, a screwdriver and a 12 key. For rubber clamps, you should take only a hexagon. It is worth starting by holding the brake lever. This will push the pads against the rim. Having examined the situation, you can immediately see where something is wrong. Use this tool to loosen the washer. Then, while still holding the brake lever, align the rubber clamp in the desired direction. The same is worth repeating on the other side. This is just the first step towards a perfectly tuned brake.

    Adjusting the front brake on a bicycle

    The hardest part lies ahead. Do not be afraid, you just need to concentrate. So, you need to adjust the distance between the pads and the wheel. It is important. Again, action monitoring is similar for the front and rear brakes. It is worth remembering that if the distance is too large, the clamps will not fit well. Therefore, there will be no inhibitory effect. If, on the contrary, you leave little room for the brakes, they will strike the rim. This will quickly wear off the pads, and the wheel will constantly brake. In general, you can adjust the distance between the pads and the rim using one nut, which is located on the levers, on top, where the metal cable is attached.

    It should be unscrewed, thereby loosening the grip. From this action, the levers will part, do not be afraid. With the force of your hand, you need to lean against the rim. Then squeeze the brake lever so that it does not reach the steering wheel for a couple of centimeters. Keeping the levers in the same position, screw the nut back. Adjusting the brakes on a bike doesn’t stop there.

    Spring tension

    The springs that are part of the mechanical rim brake system are also responsible for the distance between the wheel and the block. But, unlike a nut with a cable, they allow you to adjust the distance down to a millimeter. That is, more precisely. The spring tension can be changed with a single bolt that is screwed on and off every now and then. This bolt is located on both sides of the brake. Therefore, when a situation arises that one side touches the rim, and the other is separated, you just have to turn the bolt. and everything will fall into place. When this element is twisted, the spring becomes “harder”. Consequently, the distance will increase. If you unscrew the bolt, the spring will weaken. From this the distance will decrease. So, by adjusting each element, you can achieve perfect accuracy.

    Disc brakes

    Bicycle disc brakes can be adjusted with just two screws. The first is responsible for the distance between the disc and the pad. The second is responsible for its location in the vertical plane. Therefore, if the rubber clamps are constantly touching the brake or, on the contrary, the disc has left the “contact zone” of the pads, you just have to work hard with a screwdriver. Through trial and error, you can understand what is responsible for what, and then. a matter of technology. By tightening the screw, you can immediately adjust the position.

    Hydraulic disc brake

    Adjusting the brakes on a hydraulically equipped bicycle is difficult. To do this, you need to have special tools and special skills. But you can do everything to prevent breakdowns. Prevention will help the hydraulics not break down and serve the owner for a long time.
