How To Adjust The Handbrake On A Bike

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.

Disk

The disc mechanism was originally the preserve of cars and motorcycles. Over time, this system migrated to Velomir. It consists of a brake disc, a wheel attached to a 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;
  • Work efficiency in any conditions;
  • Can be installed on wide tires;
  • The durability of the pads;
  • Mechanism does not affect rim wear.

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 has a high cost.

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 cable.

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

  • Simplicity of construction;
  • Maintainability both at home and traveling;
  • High braking performance;
  • Versatility;
  • Light weight.

Rim brakes are NOT without flaws. Products are characterized by low modulation, sensitivity to the curvature of the rims. Moisture and dirt impair the operation of the mechanism, with prolonged use, the structure heats up, which leads to abrasion of the pads.

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

Every year the number of lovers of riding on 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.

What tools will be needed during adjustment and installation

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

  • Screwdrivers. Phillips and flat head screwdrivers 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;
  • Bicycle caliper, adapters, pads, lever;
  • Cables;
  • Rotor, a 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.

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.

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 second 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.

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.

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.

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.

Adjust the position of the pads

“Fasten” the brake by squeezing the levers and placing the cable guide (C) in the stop (D). Loosens shoe retaining bolt (K) with a hexagon. Presses the lever with the block to the rim and set the block so that it:

  • Adhered to the rim with the entire surface
  • Did NOT touch the tire
  • Placed parallel to the rim

In this position, the block must be fixed by tightening the bolt. If the bolt is heavy, the block can move, and it needs to be corrected. It will be easier if you find an assistant who will grip and hold the brake lever while you tighten the bolt.

If your brakes squeal, try the following.

Before tightening the bolt, place a folded sheet of paper under the rear (in the direction of travel) of the shoe, then tighten the bolt. So the pads will be smoother to press against the rim when braking (first by the front, then by the rear) and will NOT “creak”.

Do the same with the second block.

How to set up rim brakes

Vibrators are NOT losing popularity. Ease of maintenance, cheap consumables and unpretentious operation. an excellent option for those who use a bicycle primarily for moving, without extreme and overloading.

The principle of operation is elementary. when pressed, the brake lever pulls the cable (G), which moves the brake levers (I), presses the pads (J) attached to them against the wheel rim. When the handle is released, the levers return to their original position, installed on them by springs. In this article we will analyze how to set up and adjust rim brakes:

Brake adjustment (V-Brake): 7 comments

Sheer nonsense is written: “At the bottom of the levers there are special bolts that regulate the tension of the springs, which press the pads to the rim.”. With what fright do the springs press the pads to the rim, if their task is to remove the pads from the rim? When we tighten the adjusting bolt on the handle, the pads are not closer, but farther, and, accordingly, vice versa, when unscrewing the pads CLOSER.

Correct and DO NOT disgrace, but Better not to meddle in questions that you absolutely DO NOT understand.

There is one cable and two pads. The springs press the shoe against the rim, one stronger, the other weaker. This allows the pads to be equally spaced from the rim.

Wash an excellent article. I began to understand what was happening and set up the rear brake.
Smit. thanks for the amendment about the spring adjusters, this clears all other questions.
Thanks to the author for the intelligible presentation and images of adequate size and quality.
PS: I’m not that stupid, but when adjusting the handles I confused the front with the rear and after 5 minutes of adjustment I accidentally adjusted the front brakes)))

Thank you very much only I knew it

Thanks! Clear and well stated.

And after all, not a single surveyor can really explain how the adjusting screw works, which is responsible for the tension of the cable on the steering wheel. Why, when unscrewing, its cable is stretched and vice versa ?

The cable length does not change. When unscrewing, the tube is lengthened by the length of the unscrewed thread, the cable has nowhere to go and it pulls the pads. It’s like with sleeves on a shirt, the longer the sleeves, the less the arms are visible.

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.

How to adjust the handbrake on a bike

Second phase. Adjusting the brake pads

What must be ensured when adjusting the brake pads? High-quality fit to the rim. This requires the correct setting of their position to the rim and setting the clearance in the inoperative position. The distance between the shoe and the rim should be 1mm. But! If you have soft type pads, the distance between the front and rear of the rim pads should differ by 1-1.5 mm. A wedge spacer must then be used to set the correct clearance.

So let’s get down to the process,

  • First, release the pad fastening nut so that it becomes movable.
  • We install a wedge-spacer between the shoe and the rim if you have soft pads, if the pads are with a metal base, then we place them parallel to the rim.
  • Rotate the pads so that they are parallel to the top of the tire. They must NOT extend beyond the rim or touch the tire.
  • Using washers Fix the position and clamp the fastening nut.

This stage is completed. go to the next.

The need for adjustment and adjustment

The brake is the main means of preventing accidents while driving, their reliability and correct adjustment ensure the safety of the vehicle and the passenger.

Adjustment procedure

First of all, you need to prepare the tools, place the bike upright and fix it in the special supports-racks.

Brake Problem Symptoms and Adjustment Frequency

First of all, you need to check the performance of the brake system.

  • Raise the front wheel so it does NOT touch the surface. Gives it rotation and check if the brake pads touch the rim for a short time and if there are any extraneous sounds. If this happens, then the wheel centering is disturbed. it has “figure eight”. Before proceeding with further verification, it is necessary to eliminate this malfunction.
  • During rotation, press the brake lever. the brake pads should be applied instantly and the wheel will stop. If there is a delay in braking or wheel slip, then a brake adjustment is required.
  • Raise the rear wheel off the ground and repeat the above procedure.

Since the elements of the brake system are in close contact with the environment, check the appearance and condition of the brake pads and cable control. It is necessary to clean them of dirt and pay special attention to the condition of the cable. damage and rupture of even one strand can cause trouble, so they must be replaced.

So, the performance of the braking system has been checked.

When do you need to adjust and adjust the brakes?

In the following cases:

  • After purchase and a small run-in under load, inspection and adjustment of all systems is required. including the brake.
  • After mechanical impact on the bike. impacts and falls.
  • After long-term storage. Especially in unheated rooms.
  • During the movement, extraneous sounds appeared. knocking and creaking, or a periodic whistle.
  • The response of the braking system to control has changed. delayed response or, conversely, release.

The performance of the braking system is especially important if you have a mountain bike.

Consider the adjustment procedure for the most common bicycle brakes. mechanical rim.

How to adjust the brakes on a bike

Fourth stage. Setting the brake stiffness (adjusting the brake cable)

At this stage, it is necessary to establish a comfortable and reliable operation of the braking system, depending on the pressure on the brake lever, located on the steering wheel. The position of the brake lever was established at the first stage of the system adjustment. Now you need to adjust the tension, and if necessary, the length of the cable.

To do this, simply press the brake lever. The pads should press against the rim with minimal lever force. If necessary, adjust the length of the lever stroke as you like using the tension nut located on the lever itself. We DO NOT set the stroke large, this is not recommended by all specialists.

All the necessary work has been completed. It remains to check the performance of the brake system, which is necessary.

Stage three. Installing the brake levers

The pads are installed on both sides of the rim, and their correct operation requires centering the levers located on both sides of the wheel.

  • Press the brake lever on the steering wheel and control the simultaneous contact of the pads with the rim.
  • Press the brake lever on the steering wheel and control the simultaneous contact of the pads with the rim.
  • If there is an advance in pressing one of the pads Adjust the tension of the cable.
  • Each lever has a special tension adjustment screw. If the block touched the rim earlier, then it is necessary to increase the tension of its spring, or reduce the tension of the opposite.

Does the touch occur simultaneously? Then proceed to the final configuration stage.

First step. Adjusting the position of the brake levers on the steering wheel

Oddly enough, the first thing that needs to be adjusted is the position of the brake lever on the steering wheel. Further adjustment of the entire brake system will depend on its position. To do this, loosen the handle securing screw for a few turns and set it to a comfortable position. the brake lever should be pressed by the second phalanges of the fingers. Adjust the main position (distance to the handle) of the brake lever to a position convenient for you using the adjustment screw.

Required tools and accessories

Prepare the recommended tools and arrange them so that they are at hand. What is required?

  • The best option is a set of tools for a bicycle, it has everything you need.
  • Screwdrivers. flat and Phillips.
  • Set of wrenches or special bicycle wrench.
  • Allen key.
  • Wedge spacer for adjusting the gap (required if you have soft type brake pads without a metal base).
  • Cleaning cloth, cloth to protect against environmental dirt.

Everything is ready? Are the tools arranged in a convenient order? Is there a cloth under the bike? Is the bike in a comfortable position? Then let’s start!
