What should be the brakes on a bicycle

Caliper brakes

Used exclusively on road bikes. Although a more simplified design of caliper brakes can be found on children’s bicycles. They differ from vibracks in that both brake levers are attached to the frame with a single screw. All adjustment comes down to setting the gap between the pads and the rim using the tension on the cable. The most popular brands are Shimano, SRAM and Campagnolo.

Adjusting the foot brake | Brake system

When servicing vehicles, there are two types of brake adjustment:

The current adjustment is to maintain the effectiveness of the brakes by restoring the normal clearance between the friction pads and the brake drum and by adjusting the pedal free play.

Before starting to adjust the brakes, it is necessary to check and eliminate jamming in the brake control mechanisms, mechanical damage, oiling, wetting with brake fluid, etc. The gap between the brake drum and linings is adjusted in various ways, depending on the design of the brake.

In the presence of adjusting eccentrics (GAZ and UAZ cars), the front wheel of the car is pre-hung and rotated by hand forward, and the adjusting eccentric 1 of the front pad is gradually turned with a key until the brake pad is pressed against the drum. Then turn the eccentric in the opposite direction until the wheel begins to rotate freely. In the same sequence, adjust the gap between the rear shoe and the drum, while rotating the wheel backward. In passenger cars, when adjusting the rear block of the front wheel, it is rotated forward.

In cars with pneumatic brakes, the clearance is adjusted by changing the position of the expander 1, rotating the worm 2 of the adjusting lever. The need to adjust the gap is determined by the length of the stroke of the brake chamber rod; the stroke of the rod should not exceed 35. 40 mm. (ZIL-130 — for front 25 mm and rear 30 mm). The smallest stroke of the rods after partial or complete adjustment of the gap should be 15 for the front and 20 mm for the rear cameras. A full adjustment is made after repairing the brakes (for example, after changing the linings). In this case, the required clearance is set not only in the upper part of the shoe, but also in the lower (support) one. This gap is adjusted by turning the support adjusting pins 2.

Adjusting the free travel of the brake pedal with a hydraulic drive with the adjusted gaps between the pads and the brake drum is to establish the required clearance between the piston pusher 4 (rod) and the piston 5 of the main brake cylinder itself. This gap, which protects against spontaneous braking of the brake pads, is determined by the amount of pedal free travel and, depending on the drive design, ranges from 1.5 to 2.5 mm, and the pedal free travel. from 6 to 17 mm.

The gap is adjusted by changing the length of the pusher by screwing its hex nut 3 onto the connecting rod 1 with a loose lock nut 2, or by turning the eccentric pin connecting the pusher with the pedal.

The amount of free travel of the pedal can be checked using a special ruler.

Adjusting the free travel of the pneumatic brake pedal consists in setting the required length of the rod connecting the pedal with the brake valve lever.

Free travel of the upper end of the brake pedal should be 15. 25 mm (with the combined crane of the ZIL-130 car. 40. 60 mm). With full braking and operating pressure in the system, the pedal should not reach the floor by 10-30 mm.

The adjustment of the manual central brake consists in setting the gap (0.5. 0.8 mm) between the pads and the disc or drum. The clearance is adjusted by changing the position of the brake pads with adjusting bolts or nuts, as well as the length of the rod connecting the pad drive lever with the hand brake lever.

Mechanical disc brakes

The most popular manufacturers of such brakes are: Tektro, Shimano, Avid. The braking force is transmitted in the same way, but not to the rim, but through a cable and a mechanism called a caliper, to a special brake disc (rotor). The caliper contains brake pads, usually made of metal or synthetic materials. One shoe is usually stationary (internal), the other (external), during braking is pressed against the rotor and presses the rotor against the stationary shoe. However, there are also systems with two movable pads. These brakes are usually found on mountain bikes.

Setting these brakes usually boils down to correct (parallel) installation of the caliper relative to the rotor and setting the clearance between the pads and the rotor using the adjusting mechanisms on the caliper. The simplest brakes may not have such adjusting elements. In this case, the caliper is installed so that the inner (fixed) shoe is as close as possible to the rotor (1-1.5 mm gap), and the outer one is adjusted by the tension of the cable.

The main disadvantage of this braking system is the need for frequent adjustments as the pads wear out.

Steering wheel adjustment.

The steering wheel control depends on the correct position of the handlebars. The handlebars are considered to be correctly adjusted if the hands, elbows, back and neck of the cyclist do not tense or stiffen when riding in a comfortable position. To achieve this, it is necessary to adjust the height of the handlebar and its tilt, adhering to the following rules:

  • On a road bike, the handlebar should be at an angle of about 90 degrees. To do this, it must be installed directly above the front hub (center piece of the front wheel).
  • On a mountain bike, the handlebar tilt is 45 degrees, in which case it is set an inch (2.54 cm) in front of the hub.
  • Road bar height adjusts 3 inches above saddle level and mountain bike adjusts 4 inches lower.

Setting the speed switches.

The question of how to set the speed switch on a bicycle arises from the vast majority of two-wheeled vehicle enthusiasts. Modern bike models are equipped with two derailleurs. front and rear. To configure them, you must:

  • install the chain on the smallest star in the front and the largest in the back;
  • rotate the screw, setting the frame in such a position that the chain will be located as close as possible to the inner plate, without touching the frame when pedaling;
  • transfer the chain to the smallest rear sprocket and the largest front sprocket;
  • rotate the other screw, setting the frame to such a position that the chain will be located as close as possible to the outer plate, without touching the frame when pedaling.

To finally set up the front derailleur, its tab must be installed 2-3 mm above the chain and adjust the cable tension. Rear derailleur adjustment begins with setting the chain to the largest sprocket. It should move down one click at a time. If this does not happen, it is necessary to slightly loosen the cable by turning the drum clockwise. You will know that you are able to fine-tune your bike’s gear shifting when the chain moves softly and quickly up and down the sprockets, both front and rear.

As a rule, this is where the bike adjustment ends. It remains only to pump up the wheels, and you can go for a walk or a trip out of town. If you have additional questions. how to adjust the speedometer or bike fork, how to properly care for the bike or any others. you can always contact the specialists for additional advice.

Saddle adjustment.

It is impossible to tune a speed bike without adjusting the saddle position. Only by correctly positioning it, you can feel comfortable while riding, it will be easier for you to start moving, get on and get off the bike. The following parameters are regulated:

How Do Disc Brakes Actually Work?

  • Saddle height. To determine the desired position, you need to sit on the bike, put your foot on the pedal and move it to the lowest point. The leg should be free to reach the pedal, but be fully extended.
  • Tilt angle. The saddle is parallel to the ground or not more than 3 degrees to one side or the other.

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 process of their maintenance will depend on what type of brake system is installed on a particular bike.

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 will be that the bolts and screws that need to be twisted 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 1 mm. And both pads must be symmetrical.

How to put disc brakes on a bike?

It often happens that you buy an expensive thing, and then the same thing comes out, only with a new “trick”. It’s the same with a bike. 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 with disc brakes. And you wonder. is it possible to install disc brakes on a bike of your type? And in general, is it worth it? Let’s try to answer your questions.

If you have opted for a mechanical disc brake and you already have the correct brake levers and cables installed, you can keep them. Just make sure that the cables are not loose at the ends. If you have not 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, it can save you a lot.

How often to check the brakes?

Perform a full brake check before every ride. Make sure the brake components are in good condition and in place.

Also, have your brakes checked and serviced regularly by an experienced mechanic in order to spot problems in time that you did not notice or could not fix due to lack of experience. If you rarely ride a bike, the brakes should be adjusted approximately every six months. Have your bike serviced more often if you use it more or more frequently.

V-brake and disc brakes. which are best for a touring bike?

Welcome to the velo-travel.com portal. Today we are going to discuss which brakes are better for cycling bikes: disc brakes or v-brakes, and why? We will also discuss all your questions.

Previously, touring bicycles of the USSR were equipped with old claw brakes. Or, as they were also called “crabs”. Such brakes were good on the HVZ road specimens, they were light, and there was no need to stop abruptly in road cycling.

What are the responsibilities of the touring bike braking system? It is the search for the answer to this question that we will do. And when we find the answer, we will make the right choice of brakes.

Brakes, first of all, must be reliable, secondly. powerful, and thirdly. easy to maintain.

Why reliable? On the hike, you will not have a set of super keys, a dry garage with excellent lighting, and a bike manual downloaded from the Internet. A hike is a trip in which all halts and overnight places are timed, which is why, on a hike, no one likes to waste time and energy simply. After all, the goal of the trip is to get the maximum amount of positive energy.

Why powerful? Because while hiking on a bicycle there is still a bag, the weight of which can reach 30 kg and more. As the mass of your vehicle increases, the requirements for the brakes also increase in order to stop you and your horse clearly in time.

Why are they easy to maintain? Because even the most reliable brakes tend to break. Unfortunately, there is no one and nothing eternal Also, no one canceled the law of meanness. In the campaign, it manifests itself approximately as follows. You will need what you forgot to take and what you did not have time to control will break. Therefore, the complex design of the brakes often puts the owner of the bicycle in an uncomfortable position, when it is impossible to repair the brake without a special tool.

Let’s move a little away from the topic, and we will tell you a similar case. We were on a small bike trip along the banks of the Southern Bug. Eugene was on a simple single suspension aluminum bike, and everyone else was on top bikes. We were driving through the forest, and one of the participants ran over a stick. The stick broke and one of the halves hit the rear derailleur hard. The brand was Shimano Deore LX or something like that, I don’t remember exactly anymore, in short, at that time that unit was very fat. So this is what happened due to the fact that the top versions of bicycle components.

And so, we announce our competition for the title of “Touring Bike Brakes”!

Today’s candidates:

Disc brakes. Mechanical or hydraulic brakes? Let’s analyze!

These are all our candidates. Why don’t we take cantilever brakes into account? This is an outdated option. Read more about the types of brakes here.

Bicycle Rim Brake Identification. What Type of Brake Do I Have?

Vi-breaks are the most popular type of brakes in the late 20th century and early 21st century. They are simple, inexpensive, and reliable. Only a few, after reading our article plan, will notice that we did not specify what kind of vibrating racks would be. hydraulic or mechanical. Yes, I did it on purpose, because rim hydraulics are only used by the elite of road cycling.

What is the advantage of V-brake brakes? It’s all about the “inhibitory” shoulder. The braking point on the wheel when using v-breaks is the point on the rim of the wheel. Accordingly, the length of the braking arm is practically equal to the radius of the wheel. This type of braking creates forces that deform the wheels. The first element that receives the braking force is the rim. The thickness of the rim is made with an appropriate margin, which is why the mass of the wheel increases. Read about the material and the correct choice of rims here. For now, we will only clarify that the best option for a hike would be two or three chamber rims, not of Chinese origin. Shockproof aluminum rims (two-chamber) are very common. From the personal experience of our team, it should be said that even 10-year-old aluminum single-chamber rims, with the correct tension of the spokes, quietly perform their functions in cycling and pokatushki.

The next element of the wheel that lends itself to deformation is the same spokes. As stated above, the correct spoke tension will ensure the reliability of the entire wheel. Remember, the reliability of the whole is defined as the reliability of the weakest link. Rim brakes are much more tolerant of hubs than disc brakes. This is all due to the fact that part of the braking force is dissipated into the spoke tension. In other words, the hub does not receive the load as sharply, which is an important plus when your bike has a large inertia force (for example, a bike is equipped with a trunk).

We examined the principle and action of forces during v-brake braking with brakes, and also clarified all the pros and cons of these processes.

And what are the disadvantages of such brakes? Why does everyone want to install disc brakes for themselves? We will talk about the advantages of disc brakes in the second paragraph of the plan, and now read about the disadvantages of v-brake brakes. The point is that the braking force with such brakes is quite large, but the response speed is low. That is why these brakes are considered ineffective by all. We figured out with you that they have a lower response speed, but in no way insufficient braking force. In addition, we have already talked about the brake shoulder, it is easier to stop the wheel by “grabbing” the rim than grabbing the brake disc.

Eights on a wheel are a hindrance to rim brakes. This is perhaps the biggest drawback of the v-brake. For precise operation of such brakes, a perfectly flat rim is needed.

brakes, bicycle

Another significant disadvantage is a squeak during braking and a decrease in braking efficiency after driving through a deep puddle, swamp, or when driving in snow.

READ  Doesn't Shift Front Derailleur On Bicycle

Dirt easily gets onto the rim and then into the braking area. Due to bits of dirt, water, or ice that freezes in winter, the brakes practically do not brake. Fortunately, this is all fixable. When driving through a deep puddle, it is worth drying the brakes by briefly pressing the brake lever.

To prevent dirt from interfering with braking, it is worth choosing pads with dirt-diverting grooves. And the rim is better to buy with a ceramic coating. If you want to extend the life of a rim, it’s worth buying a quality rim and the brake pads are not too stiff.

Another disadvantage of the v-brake is the ability to expand the feathers during hard braking. This can be easily eliminated by installing a special arc called brakebooster.

And so, the final disadvantage of vibrake brakes is the impossibility of installing wide tires (wider than 2.5 ″). Although, this problem is also contrived by marketers, for the sake of attracting attention to disc brakes.

Fitting very wide tires occurs in two cases: if you ride in extreme discipline, or if you ride on sand and snow. Yes, in the first case, disc brakes are essential, v-brakes are not listed for many reasons. But in the second case, the problem can be solved by installing cantilever brakes. We wrote about them in the article about brakes.

Well, now, with the baggage of new knowledge, we turn to the disc brakes review in order to make an objective choice in the nomination “Best brakes for a touring bike”.

So, disc brakes have a number of properties that make everyone want to install them.

Quick response is their strong point. Thanks to the short disc brake lever, the handle travel is significantly less than when braking with Wi-breaks, which means that it makes no sense to clamp the handle all the way.

The second advantage of disc brakes is excellent performance in all road and field conditions. The disc rarely gets dirt and water. It is easy to deal with icing, one disc drying removes the ice crust for the whole ride.

Adjusting the clearance between the brake pads and the disc is very simple and long lasting. Also, it is worth mentioning that disc brake pads are more wear-resistant than v-brake pads. And yet, for disc brakes, the presence of eights on the wheel is not important. The last plus of disc brakes is the disc itself. During braking, it is he who heats up, not the rim. This means that prolonged braking will not harm the rim and tire, as is the case with v-brake. In addition, the brake disc has cooling grooves and holes.

If disc brakes are so practical, what’s the catch? There is no catch, there are a number of disadvantages. The fact is that the braking shoulder when using disc brakes is much less, respectively, the load on the hub and on the spokes is much higher. This is not so noticeable when you are alone on the bike, but if you have a large bag with you, this is already a load on the braking system. The problem is that nothing will happen at once, but after long trips with a trunk, problems will begin to creep out.

Another disadvantage of disc brakes is the cost of maintenance. Brake pads are much more expensive than rim brake pads, but that’s not all. Not only does each manufacturer have its own brake pad shape, but individual models from one manufacturer have a different type of brake pad. If it is easy to find pads for top-end brake models, then on budget models you will have to select pads by the “typing” method.

Another significant drawback of disc brakes is oil. An accidentally dropped drop of oil while lubricating the bike. and the brakes will slow down badly or squeak, because the brake pads will quickly become saturated with oil, and the disc itself will be covered with a thin film of oil. Is it hard to believe these lines? Enter a search query in Google or Yandex: “squeak in disc brakes” and you will see how many discussions on this topic. And all because of the oil that once accidentally got into. It turns out that everyone avoids the V-break brakes because of the squeak, and they themselves get squeaky disc brakes.

And so, disc brakes are still mechanical and disc. Which is better? From practice, I would like to note that good mechanical brakes are much better than budget hydraulic ones, this is unambiguous. The hydraulics are worth their money. braking power, precision work. it’s very pleasant while driving. But hydraulics require care and special tools for maintenance. Replacing the hydraulic line on a hike is a very risky business. If you can still pump the brakes in dry weather, then in rain and mud it is almost impossible to do it. Disc brakes are good for competition, city bikes, and HH, but not for touring. It’s like driving a planted car on our roads, seemingly cool, but not practical and not effective. Let’s summarize?

The main advantages of v-brake brakes are the minimum load on the wheel when riding with a bag and lightweight, both economical and physical

The main advantages of disc brakes are quick response and trouble-free operation in all weather conditions.

And what to do in such a situation? Which brakes are better than v-brake or disk? If we ask a question in the commentary, then a verbal skirmish will begin between the supporters of disc and rim brakes. And we will offer you the best option. to ride without brakes! You lose all the problems and at once

Jokes aside, the best option is to install a disc brake in the front and a v-brake in the back. Thus, the rim brake at the rear will not negatively act on the wheel loaded with the bag, and the disc brake at the front will provide reliable braking in all weather conditions. It is not for nothing that disc brakes are installed in front of cars, and drum brakes at the back, the principle is almost the same.

That’s the whole secret to using brakes rationally and achieving effective results on a hike.

Thank you all for your attention and good luck.

Drum bike brakes

When we press the pedal back, the fitting begins to move along the thread until it stops When it comes to the stop, it locks the pads and presses them against the glass

Read about the drum brake device on a bicycle in a separate article. In a nutshell, the principle of a drum brake, or it is also called a foot brake, is as follows. Inside the rear hub of the bicycle wheel there are several parts, 2 pads and one part that has a thread. When the wheel rotates backward, this part is twisted moving another part, which presses the pads against the wheel hub and stops the wheel.

Most often, these bicycle brakes are used in older type road bikes. Such bicycles were in Soviet times Ukraine, Shkolnik, Orlyonok and the like. They do not provide for gear shifting through sprockets. A similar type of brake is also used in bicycles with a planetary hub.

By way of transmission of braking force

According to the method of transferring the braking effect to the brake itself (it does not matter whether it is a disc brake, or a rim brake), bicycle brakes can be divided into:

  • mechanical
  • hydraulic

In both cases, we press down on the brake lever on the bicycle handlebars. If it is a mechanic, then the brake lever is connected to the bicycle brake itself by means of a metal cable and when the brake is pressed, the cable is stretched pressing the pads against the rim or rotor

In hydraulic brakes, a hydraulic line (tube) filled with oil fluid passes from the brake lever to the brake mechanism. When the brake handle is applied, the brake fluid inside the tube begins to move under pressure and transfers force to the brake, after which the brakes are applied.

In the case of hydraulics, the force transmitted to the brake can be very small, that is, we can brake with almost one finger and do not have to put too much pressure on the brake. In mechanics, the effort must be greater. This will be discussed in more detail below.

Let’s try to figure out what is actually better and why just below.

So let’s get down to a more detailed description of each type of brakes and weighing the pros and cons.

Cantilever brakes

This is an outdated type of bicycle brake as it shows poor performance in extreme situations. Now they are mounted on some models of cyclocross bicycles, less often on road bicycles. They are structurally simple. two elements are movably fixed in the holes. The drive is provided by the presence of the upper link.

These brakes are initially puzzling. “do they really work.” Budget models, when they have not yet got used to the pads, do not provide braking at all, this moment requires getting used to and specific skills. Later, when the pads are worn down, the brakes function well.

Mid-range models slow down well with normal pads. But high-quality options for brakes of this type work effectively with new pads, and after grinding them in, they brake well at all, comparable to other rim models and even with a budget version of disc mechanics. Cantilever brakes from Avid Shorty Ultimate or TRP Revo X are effective.

The main types of bicycle brakes and their differences from each other

Bicycle brakes are classified into several types. First, we will list them, and then we will analyze in more detail the pros and cons of each type.

General classification

Every novice cyclist soon thinks about upgrading his bike and thinks what to change first, or maybe even switch to new brakes. Here the question arises before him, what kind of brakes are there on bicycles, how they differ and how to choose the ones that are right for his riding style.

Roller brakes

The principle of action is very similar to a drum brake. The roller brake itself on the bike is not inside the hub, but outside. It is attached to the bike frame and braking is not due to the foot brake, but due to the handle on the handlebars of the bicycle. From the brake lever there is a cable that, when pulled, triggers the roller brake mechanism.

The main parts of the bicycle brake are shown in the picture. Outside the drum wall, inside the drum there are 3 pads, 6 rollers and an eccentric. The eccentric is connected to the brake lever by means of a brake cable. When tensioned, the eccentric turns and begins to press the rollers against the pads. The pads, in turn, are pressed against the drum and braking occurs. They, like other brakes, have both pros and cons. At the same time, the advantages are quite significant.

In general, there are pluses and minuses as elsewhere. A roller bike brake is more suitable for non-aggressive driving in city, parks and the like. In the conditions of country roads, forests and the like, disc brakes are more suitable.

  • Read all the information about the roller bike brake in this article.
  • Read also what is better rim brakes or disc

Rim brakes

Rim brakes are brakes in which braking occurs when the pads press on both sides of the rim of the bicycle, as a result of which there is a gradual braking until a complete stop. The brake lever is located on the handlebars of the bicycle and the braking force is transmitted either through the brake cable in the case of mechanical brakes, or through the hydraulic line if you have hydraulics installed on your bicycle. These bike brakes are currently considered the most common on entry to intermediate mountain bikes.

By the type of attachment, they are divided into:

V-brakes are more commonly used on mountain bikes and other bikes where wide tires are present. In the case of narrow tires like racing bikes, caliper brakes are often used.

Hydraulic system and its elements

  • Reservoir with oil or special brake fluid.
  • High pressure oil pipes.
  • Brake cylinder pistons and the brake cylinder itself.

The action of a hydraulic brake in a distant approximation is similar to the action of a mechanical one, only instead of a cable moving in a sheath, after acting on the brake lever on the steering wheel, a force impulse is transmitted to the brake fluid. Its compression through the line acts on the power pistons, and they, moving in the cylinder, transmit the force to the brake pads, stopping the bike.

But adjusting hydraulic brakes already requires some skill, acquired through study or long experiential practice.

Features of rim brakes, advantages and disadvantages

What are rim brakes? These are two friction pads with a very high coefficient of friction. The force for closing the pads on the rim is transmitted from the lever on the handlebars by means of a cable. When you squeeze the lever, the correctly adjusted pads come together, clamping the rim of the bike, thus stopping the movement. Such brakes have three types, which differ from each other mainly by their application in different operating conditions.

  • Cantilevers. They are used extremely rarely, mainly on cyclocross sports bike models.
  • Caliper brakes. They are mainly used on road bikes.
  • U-brake. This is a mini v brake They are installed mainly on BMX.
  • V-brake. The most popular model of rim brakes. Named from V-shaped brake levers.

But there are a lot of complaints about the operation of rim brakes related to both the operating conditions of the bike and its design features.

“Cons” v-brake brakes

  • Poor braking performance in wet and muddy conditions
  • In conditions where there is dirt on the road, both brake pads and wheel rims suffer from increased wear: dirt works as an abrasive, erasing the pad material and metal.
  • In case of imbalance of the wheel and the formation of a “figure eight” associated with uneven tension of the spokes, individual segments of the wheel constantly rub against the brake pads.
  • Constant adjustment of the lever springs for extreme driving conditions.
  • On long descents, when it is necessary to constantly slow down, the rim gets very hot, which can even cause tire disassembly due to rubber softening.
  • The design clearance at the rim brake will not allow the vibrake to put wide rims and tires on the bike.

Choosing between mechanics and hydraulics: which is better

The mechanical system for transmitting the impulse of force to the brake shoe, by pressing the lever and displacing the cable in the shell, is more than a dozen years old. The technology has been worked out and has reached a certain development limit.

The features of this system are familiar to everyone, it remains only to recall its basic principles of operation:

  • From pressing the handle of the lever on the handlebars of the bicycle, the force is transmitted to the cable, its translational movement begins inside the shell in the direction of the driver.
  • Pulling the brake cable at the end opposite to the lever, at the wheel hub, sets the brake shoe in motion in the caliper.
  • The brake pad pressed against the rotor disc prevents the rotation of the bicycle wheel
  • When the influence of the lever on the steering wheel is weakened, the brake shoe is pulled by the spring from the brake disc.

There are fewer transmission units from the hand to the rotor disc than on the v-brake, so the modulation feels “live”.

How to use your brakes properly | Cycling Weekly

But then “interesting things” begin in the form of stretching the cable and its difficult movement inside the shell. Sometimes even jamming. if the operating conditions were close to extreme, as is the case on country dirt roads. And if the second is treated with the lubricant introduced on time, then the pulling of the cable can be compensated to some extent by twisting the adjusting support screws. And you can adjust them as long as the screw thread is enough. Then you have to change the cable.

The hydraulic braking system of the bicycle is completely eliminated from these disadvantages. True, having got rid of some, she, as often happens, acquired others.

“Pros” of vibrake rim brakes

  • Low price
  • Light weight
  • Constructive simplicity and corresponding ease of maintenance
  • The possibility of repair outside specialized workshops, literally on the road, in the field.
  • Interchangeability of budget and expensive brakes, moreover, with minimal skill, on our own.
  • Widespread use of v brake and the associated opportunity to purchase both a new brake and its components (levers, sheathed cables, friction pads on brake levers-pads).

Which is the best choice for the bike: V brake or disc brakes?

The age-old dispute between the two concepts. rim and disc brakes on a bicycle is not over yet, although rim brakes are gradually losing ground, shifting into the area of ​​purely non-professional use. Why is this happening? Let’s try to figure it out in this article.
