How To Adjust The Brakes On A Stealth Bike

How To Adjust The Brakes On A Stealth Bike

Rim Bicycle Brakes

The drum brake bushing is gradually becoming obsolete. Rim and disc brakes occupy the leading positions in the market. Rims are currently the most popular, since 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 lever, 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.

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.
  • DO NOT interfere with the use of wide tires.
  • Work efficiently on a curved rim.
  • Long serve.
  • DO NOT need special maintenance.
  • Rotor aligns much more easily than hydraulic brakes.
  • Ropes DO NOT need special maintenance, unlike hydraulic lines.
  • NOT field repairable without special tools.
  • Due to the variety of models and modifications, finding spare parts is a little difficult.
  • During transportation of a disassembled bicycle, there is a high probability of the rotor curvature due to any mechanical impact.
  • Sometimes bike rack mounts interfere.
  • Are heavy on rim brakes.
  • More expensive than rim models.

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

It also has 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.

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 Therefore, some details are outdated and do NOT stand up to the competition. Today we will discuss the 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 you-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.

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 brake lever travel.

Disadvantages of hydraulic brakes:

  • Hydraulic line repair is quite problematic.
  • If the rotor is bent, it is difficult to align.
  • Highest price for second types.

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

Cantilever brakes

The mechanism consists of two levers, each of which has brake pads. The levers are attached to the pivot on the fork. With the help of two rods, the cable moves the levers, which 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.

Hydraulic rim brakes

Unlike the two previous types, in the design of such brakes there are 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 perpendicularly to the rim, causing friction and braking. Bicycle brakes of this type are very effective, so they are used in trials. Due to the high weight, difficulty in maintenance, poor modulation (the 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.

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 the rotation of the carriage in the opposite direction, the brake pads 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 bicycles, 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, and do not require fine adjustments.
  • Heavy weight.
  • It takes a lot of effort to brake.
  • Unable to use on multi-speed bike models.
  • The presence of a dead zone. Braking is not possible when the connecting rods are upright.
  • 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 type II brake on the front wheel.

Braking system characteristics

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

  • Impact strength;
  • Efficiency;
  • Wear resistance;
  • Modulation;
  • Service requirements;
  • Comparative features.

The 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 instructions 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 machine, 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 with attachment 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 fixed on 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 mount of the arcs.
  • Through the cable, the force is directly transmitted to the clamping part of the arcs, due to which they are compressed, and the pads come into contact with the rim.
  • The release is responded by an elastic metal insert or spring built between the levers.

The levers have a single 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 work is to extend the levers under the action of a taut 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 fixed to the frame.
  • Due to the convergence of the levers, the pads approach the rim.

The cantilevers are dirt-resistant and will not bump tires and are easy to install. Significant disadvantages include:

  • Decrease in braking force as the leash is extended;
  • It is required to create a high force to stop the bike completely;
  • Difficulty of adjustment.

In justification of 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. In comparison with the cantilever, it has a higher accuracy and longer life of the pads. They are also easy to remove and repair yourself.

The vectors are partially similar in design to the cantilever: with the help of bolts, the front brake levers are attached to the fork, and the rear ones. to the upper stays. The legs are tied together with a pulling cable. Drive cable Lead to one side, but due to the straight shape 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. That, in turn, move the pads towards each other.

Advantages. high compression force and efficiency, excellent modulation. Disadvantages. deterioration of performance in case of blockages in the hydraulic line, complex repairs. Used a similar type of brakes for freeride and trial.

In rim type brakes, the pads’ travel is slow, due to which they wear out less during operation. A significant disadvantage of this approach is the impossibility of being 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 set up rim brakes on a bicycle

The braking system is one of the most important technical components of a bicycle. Her condition directly depends on the safety and the cyclist worthy of the road users. Serviceable 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.

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 the compression of the handle and rebound when it is released. If the pads do not move away from the rims, this indicates insufficient tension. On the overtightened 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.
  • Select the tension so that in the fully clamped position the distance from the handle to the steering wheel corresponds to the thickness of the finger.

If damage has been noticed on the cable sheath, it is recommended to immediately put 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 of the rim plate 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 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.

Tension adjustment

If the adjustment of the screw is not enough, you need to shorten or lengthen the cable. This is done on the very brakes. Opposite the shirt, on the opposite element, clamp the cable with a lock, which is unscrewed with a hexagon. To do this, unscrew the retainer bolt, tighten or loosen the cable, screw the retainer back. The excess length of the cable can be cut, although many leave it twisted in case of breakage, although practice shows that such “reserves” do NOT help anyone.

How to adjust rim and disc brakes on a bicycle

Brakes, especially disc brakes, need to be adjusted very rarely. For rim types, this is once a season, for other options. up to once every few years. However, after a long downtime or repair, as well as when symptoms appear Incorrect operation of the brake system, adjustment is simply necessary.

Disc brake adjustment

Disc brakes are rare items for adjustment or maintenance. Nevertheless, they sometimes have to be dealt with. Consider how to set up the brakes on a bike with a rotor and caliper.

Shoe position and tilt adjustment

After loosening or completely unscrewing the pad fixing screws, they can be shifted in any direction.

This adjustment should be done, not removing the wheels, in order to clearly position the shoe. So, how should the block stand:

  • The block should be at the level of the rim, not a millimeter beyond it.
  • When checking for clearance from either side, the block should be in both the braking position and in the open position parallel to the rim.
  • When spinning the wheel, the block must be pressed exactly along the rotation vector. deviation from it will lead to damage to the brakes.

After installing the pads in accordance with these conditions, the screws are tightened, the brakes are checked.

Adjusting the rim brakes

Adjustment of rim brakes (almost all modern ones are of the V-Brake type) is very simple and does not require any special conditions. Moreover, due to the “openness” of the mechanism, maintenance usually consists not in working with the structure, but in replacing the pads.

Symptoms of problems

How can I tell if my bike needs brake adjustment? There are several signs:

  • You bought a bike. new mechanisms require running-in and constant, in several approaches after a short run, adjustment.
  • You have NOT used the bike for more than a month. especially if it was cold storage, maintenance of the pads and brake mechanism is mandatory.
  • “New” sounds are heard from the mechanism: buzzing at speed, periodic knocking, whistling, squeaks. problems with mechanical parts or block.
  • The brakes began to react poorly to effort, that is, they only work after some gait, and not immediately “release”, etc. a clear sign of cable or hydraulic problems.
  • Visual damage to the cable or elements of the brake mechanism. they can continue to work, but it is simply necessary to adjust after, for example, an impact.

Renewal and replacement of pads

The most common service is replacing or renewing a bicycle brake pad.

Updates are usually sufficient after long-term storage. The surface of the rim and pads is degreased, and, depending on the remaining thickness of the rubber, its top layer is removed, as it “dubs” from frost during storage, as well as from heating during active braking.

Less common is the replacement of the pads. After unscrewing the screw, the old shoe is pryed off and removed, and a new one is installed in its place. Here, care is required when choosing, since there is a single standard, and the groove for the screw may NOT fit, and the shoe itself on the platform may NOT lie down. Fortunately, any sizing problem is resolved with a sharp knife. In the case of cartridge pads, undercutting is unlikely to help, but this is rare.

Removing the brakes

We go through the following steps:

  • Opening the brakes, under force Removing the cable jacket from the holder.
  • Unscrew the screw fastening to the frame.
  • Removing the brakes.
  • We unscrew the pads fixing screw, if work with pads is required.

It is very important in the last step NOT to lose the correct sequence of washers. They come in pairs. convex and concave. Further adjustment depends on their settings.

Mount types

Before adjusting, the first thing to do is to make sure that the rim brakes are indeed V-brakes. Actually, there are three types of rim mounts:

  • V-Brake. separate V-shaped levers, connected by a cable, held by a leash (jacket)
  • Cantilever. with an additional central attachment, here of which the cable goes separately to each side. In fact, these are the predecessors of the V-Brake, featuring a more complex mechanism, but a large clearance, which is beneficial for “dirty” riding;
  • Caliper brakes. U-shaped mount in which two levers are connected and “bite” the rim. Such models will weaken the hardest.

Each type is understood in different ways, but the vast majority will only have to deal with the first type.

How to install a new mechanical disc brake

  • Attaching the brake arm to the handlebar so that it is flush with your forearm. If necessary, adjust the distance from the handle to the grip, at which, grasping the steering wheel with your whole hand, you could normally reach it with your index finger.
  • Install the adapter on the frame and tighten the bolts until fully tightened, alternately tightening each bolt.
  • Passing the cable with a shirt so that it coincides with the places of its fixation to the frame.
  • We insert the cable into a special slot on the brake lever and fill in the shirt. Please note that when installing a new cable, the tension adjustment on the brake lever must be tightened completely minus 1-1.5 turns.
  • The position of adjusting the tension of the cable on the caliper is set similarly to the brake lever. Passing the cable into the hole on the caliper, we put it in the groove of the cable retainer and, pulling, clamp the fixing bolt.
  • After that, we put the end fittings on the end of the cable and squeeze it. This is necessary so that the cable does not fluff.
  • Next, we proceed to the adjustment, which is described below.

How to properly adjust the brakes on your bike.

In the disc brake system, parallel to the disc, there is a part such as a caliper. The specified element influences the wheel movement to a small extent. If it is necessary to adjust the bike with such a brake system, we advise you to tighten the hex so that friction arises and is felt in the area of ​​the wheel, disc or pad. In this case, the required distance between the brake lever and the grip must be observed.

You cannot fully tune your bike without adjusting the wheel spokes. And if it turns out that they are unstable, a special type of key (spoke key) will be required. This procedure requires experience and Appropriate tools), so we do NOT advise you to do this type of tuning yourself. You can harm your vehicle. Repair and maintenance of bicycles. the competence of specialists in this field.

Queue for tires. determine the degree of their fullness and wear, which should have reasonable limits. The handlebars have details such as shifters positioned to extend the cyclist’s hand. And if you see that this condition is NOT met, you will need to loosen the mounting bolts. If you try to do it yourself, you risk ruining the mechanism. Therefore, bicycle repairs will be performed accurately and with high quality by the masters of the VeloTemp company.

What to do before adjusting the brakes

If you need to adjust disc brakes that have already been in operation for some time, then before making the adjustment, it is advisable to perform the following preparatory work:

Disc Hydraulic Bicycle Brakes

Disc hydraulics are very similar to their mechanical counterparts. The main difference is that the force applied to the brake lever is transferred to the pads not by the cable, but thanks to the DOT4 brake fluid (on Avid, Hayes, Helix brakes) or mineral oil (on Shimano brakes). Next, consider the design of hydraulic disc brakes.

  • Brake handle. Actuates the piston, which presses on the brake fluid.
  • Brake lever adjuster. As in disc mechanics, it is designed to adjust the position of the handle of the steering wheel.
  • Master cylinder. It consists of several parts. An expansion tank with a lid serves as a brake fluid storage. The cap is used when filling and bleeding the brakes. Inside there is also a piston with a cuff and a return spring.
  • Hydraulic line. It is a durable hose that connects the master cylinder and the caliper.
  • Caliper. A mechanism that, when pressure appears in the hydraulic line, activates pistons that push the brake pads.
  • Brake pads. They serve to convert frictional force into thermal energy, thereby stopping the bike.
  • Adapter. The part that attaches the brake caliper to the fork or bike frame.
  • Rotor. It is a perforated metal disc, in which, when the handle is pressed, the pads rub.

How to set up the gearshift system.

When it is required to adjust the rear derailleur, specialists, first of all, will release its cable by dropping the shifter by about 1, set the roller by rotating the bolt and return the settings to their place, and not forgetting to recheck the shifter after completing the actions. Overtightening the bolt can easily damage the cable or thread.
Regarding the tuning of the forward gear, by releasing the tension in the cable, achieve the correct transfer setting, ensuring it is in a state when it is parallel to the largest sprocket. It is imperative to release the transfer of the upper and lower links. In this case, the position of the clamp of this part of your bike can be either upper or opposite to it. lower. In any case, you should not risk it, because repairs and maintenance of bicycles must be carried out only by professionals.
If the clamp is in the upper position, and the distal adjusting bolt is closer, this is correct. Accordingly, you should initially adjust the position of the remote part of the bicycle frame, so that later it becomes closer to the chain. In this case, the parts should not touch. Please note that the chain must be spinning on a small star. Pull the cable with one hand and fix the bolt. At this point, there is a risk of damage to the thread, therefore, it is imperative to carry out the repair process.People must be competent to avoid damage to the mechanism.

When all the work is completed successfully, the last procedure remains. Adjust the saddle so that it matches your height and limb length.
Giving your bike for repair work to proven and highly qualified craftsmen of the Velotemp company.

How to properly adjust the steering wheel, steering block and stem.

If you have problems with a bicycle handlebar, steering block or stem, it is better to entrust the bike repair to the trusted specialists of the VeloTemp bike workshop, who guarantee the quality of the work performed and a conscientious attitude. They will also check how the steering system is set up, test the degree of tension of these elements. To adjust the functioning of parts, specialists cannot do without a hexagon. You should also exclude the presence of a backlash, and if it is detected, you need to urgently take measures to eliminate the problem of auto products.
Do not forget that the steering wheel should also be adjusted from time to time. This process involves clamping the steering head with special wrenches. Make sure the steering wheel is tight enough.
Only experienced specialists will fully and accurately repair the bike without damaging its mechanisms. Modern bicycles are expensive enough to take risks and carry out repair work on their own.

Disc Mechanical Bicycle Brakes

Disc mechanics is of the following design.

Braking system characteristics

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

  • Impact strength;
  • Efficiency;
  • Wear resistance;
  • Modulation;
  • Service requirements;
  • Comparative features.

The 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 instructions 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 machine, 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 with attachment to the fork or stays of the bicycle frame. Design features and operating principle:

  • The release is responded by an elastic metal insert or spring built between the levers.

The levers have a single 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 work is to extend the levers under the action of a taut 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 fixed to the frame.
  • Due to the convergence of the levers, the pads approach the rim.

The cantilevers are dirt-resistant and will not bump tires and are easy to install. Significant disadvantages include:

  • Decrease in braking force as the leash is extended;
  • It is required to create a high force to stop the bike completely;
  • Difficulty of adjustment.

In justification of 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. In comparison with the cantilever, it has a higher accuracy and longer life of the pads. They are also easy to remove and repair yourself.

A significant disadvantage of this approach is the impossibility of being 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 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 tighten 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 at 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 the pliers part of the cable and tighten the bolt, applied 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 setting of the brake system for rim and disc types is different, since different rotating mechanisms and pads are used.

Adjusting the rim brakes

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

READ  How is the chain on the bike

Note: it is important to observe three main rules:

  • Pads must 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 need to press the brake lever and watch how the pad 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 block 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 particular 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 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”. sit on the bike and ride 3-5 meters, braked sharply. If the bike stops even when the brake lever is pressed to a minimum, then the system has been serviced correctly.

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 depend on the process of their maintenance.

Setting up disc brakes

As a rule, the adjustment of the disc brakes is to periodically tighten 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 in the Hydraulic and mechanical system 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 nuance should be taken into account. if the hydraulic system is of a closed type, then you will have to adjust the pads manually. 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.

After carrying out the work, be sure to check the operation of the brake system in action. ride your bike 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.

Varieties and models of bicycle brakes

Adjusting the brakes 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 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.

Defective brakes

Bad brakes are every cyclist’s problem. I don’t really want to carry out checks before every 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.

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 is oil, or, as it should be 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 are simply impossible to fix 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 ruptures, brake fluid will escape. Therefore, brakes can only be done 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. Since the repair of the simplest brake system. rim. V-breaks are NOT famous for being smart. 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 “shirt”), inside of which an iron cable fidgets. Two clips and pads. Everything is nothing more. That is why there are only three provisions for regulating the V-break.

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.

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 changes can be seen here? All the same levers, the same metal cables. Only the brake itself is 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. Therefore, it can be difficult to drive all your life on V-breaks, and then switch to disc brakes. After all, you will have to learn to configure this system again.

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 bike is a delicate thing. So you need to be patient first.

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

The person does not tolerate the striking of this element into the tires. 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 preferably there is no effect (good inhibition). 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 clips, 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. This tool will loosen the washer. Then, while also holding the brake lever, align the rubber clamp in the desired direction. The same thing is worth repeating on the other side. This is just the first step towards a perfectly tuned brake.

Spring tension

The springs, which 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 one bolt, which is now and then twisted and unscrewed. 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, we adjust each element, you can achieve perfect accuracy.
