How to make brakes on a speed bike

How to release the disc brake on a bicycle

It is enough to screw in the cable tension drum a certain number of revolutions. If its stroke is not enough, unscrew the nut securing the cable to the caliper and loosen its tension. The option is so-so. unscrew the handle adjustment bolt.

Do not forget about the fixed block. Moving away the movable friction pad with a cable, move the static one, so that symmetry with respect to the rotor is maintained.

Removing the brakes

  • We open the brakes by pulling the cable jacket out of the holder under force.
  • Unscrew the screw fastening to the frame.
  • Removing the brakes.
  • We unscrew the screw fixing the pads, if you need to work with the pads.

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

Types of bicycle brakes

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

make, brakes, speed, bike

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

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

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

Bicycle Hydraulic Brake Device

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

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

Bicycle disc brake device

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

How to adjust disc mechanical brakes on a mountain bike

Mechanics are gradually becoming history. Now it can still be seen in the budget line of Russian Stels, Forward and Stern. Considering the price, there is no need to talk about the belonging of brake system parts to such global brands as Shimano and Sram. Usually this is some kind of noname kit that has a minimum of settings.

Another nail in the list of disadvantages of mechanical disc brakes is that they need to be adjusted more often. This is because one of the pads is motionless. As it is erased, the distance between it and the disc automatically increases. Meanwhile, fluctuations in the values ​​of this gap should be insignificant, otherwise the friction linings will wear unevenly, the quality of deceleration suffers.

The main symptoms of bicycle brake malfunctions

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

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

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

Attention! Adjustment of the brake systems of bicycles is carried out in the event that you have purchased a new bike, as well as after the expiry of its running-in period.

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

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

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

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

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

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

Adjust the position of the brake lever and the tension of the cable

To bring the brake lever closer to the steering wheel (for example, so that you do not have to stretch your fingers too much), tighten the bolt on the brake lever.

In this case, keep in mind that you should not bring the handle too close to the steering wheel. It should not touch the grip when fully clamped.

When the position of the brake lever is set, it remains to adjust the cable tension. The task is to bring the pads as close to the rim as possible, leaving a distance of 2-3 millimeters between the pad and the rim.

To do this, you can tighten the cable in two ways:

    For a rough adjustment, if the cable is very weakly tensioned, and the pads are far from the rim: loosen the bolt fixing the cable in the brake lever, tighten the cable, tighten the bolt.

When loosening the bolt, hold the lever and cable so that the cable does not run away and you do not have to re-thread it into the seat.

    for fine tuning, we use the adjusting screw at the point where the shirt comes out with a cable from the brake lever.

To make the screw spin freely, loosen the lock nut by unscrewing it counterclockwise. Turning the screw clockwise, we loosen the cable tension (the pads move away from the rim), unscrewing it counterclockwise, we increase the tension (the pads are closer to the rim). When the pads are in the desired position, tighten the lock nut.

That’s all! Checking how everything works. If necessary, readjust the springs of the levers (item 3).

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. over, due to the openness of the mechanism, maintenance usually consists not in working with the structure, but in replacing the pads.

How to set up the brakes on a bike?

Bicycle brake adjustments are generally not required frequently. The standard procedure is carried out before the first ride, when the question arises. how to adjust the brakes on a bicycle. Next, you just need to keep the equipment in working order.

Still, there are situations when you need to re-adjust the brakes for a safe ride.

Adjustment is usually associated with ensuring the required distance between the brake pads, their symmetrical position in relation to each other. On a regular bike, you can pull up the cable and make some adjustments just like applying the brakes on a speed bike. The difference may be in the degree of tightening and the number of bolts.

The work of adjusting the brake system of a bicycle depends on the type of brakes. They are:

How to set up rear brakes on a bike?

You need to get to work as soon as it becomes clear that there are problems with the bike. Therefore, first you need to check the brakes. To do this, you should:

  • raise the front wheel of the bicycle, untwist it and press the brake lever, if the wheel is working properly, the wheel will immediately stop (it is important to pay attention to whether the brake lever is touching the handlebar, otherwise you will have to pull the cable);
  • now we carry out the same manipulations with the rear wheel;
  • if everything is in order with the brake lever and the cable is tightened, then you should proceed to checking the brake pads (disc brakes are more complicated than rim brakes, due to the difference between the pads and rotating parts);
  • if it is a mountain bike, then it uses a new braking system v-brake and needs to be adjusted on it.

You don’t need to know how to apply the brakes on a particular bike. On different bicycles, the location of the bolts and screws may differ, otherwise the principle of operation is identical.

What to look for first when setting up rear brakes on a bike?

The main thing is to check the placement of the pads parallel to the rim. Next, we do the following work.

You need to find a hex nut in order to loosen the block. Next, you should press the brake. check how tightly and in what place the rim touches. The pads can be extended, displaced, moved, and then the bolts can be tightened.

It is necessary to adjust the distance between each block and the rim separately so that they are at the same distance of about 1-3 mm. Although a lot depends on the specific bike model. Now it is enough to slightly press the handle to start braking.

After adjusting the brakes, be sure to check their action on the go. Therefore, you need to ride a bicycle for several tens of meters, alternately gaining and decelerating speed, changing a smooth and abrupt transition to braking. Should work one hundred percent.

If, while pressing the brakes, the wheel continues to rotate for a long time, you should re-check the systems, fasteners, the distance between the pads or discs. The service brake is in good working order immediately.

Adjusting the braking system of the bike allows you to eliminate any blemishes. But sometimes you have to deal with not only tuning, but also replacing the pads if the brakes on the bike do not work well. precisely, pad replacement is required due to erasure. over, the rim type of pads wears out faster than the disc.

With open hydraulics, the brake system automatically adjusts the work of the pads. Having installed a closed hydraulic brake system on your bike, all adjustments will have to be made for it (you will need special valves).

After driving on a smooth road, you can determine how quickly the braking system responds to a braking command. You can check the equipment on different sections of the road. ups, downs, irregularities. so that there is no doubt about the serviceability of the equipment.

How to set up the brakes on a bike

How to set up the brakes on a bike

The question of how to set up disc brakes on a bicycle is extremely rare for owners of respective vehicles. Unlike rim pads, which require preventive maintenance at least once a season, disc adjustments are performed much less frequently, usually no more than once every 2-3 years. Except in cases of prolonged downtime and obvious signs of incorrect operation. Here, surgical intervention with subsequent adjustment measures is simply necessary.

Experienced cyclists are familiar with the list of causes of a faulty braking system or situations where additional adjustment is indispensable.

The main reason for incorrect operation is worn pads. Buying a new vehicle is always accompanied by its individual adjustment. If you become the owners of a brand new two-wheeled friend, then its mechanisms must be run in, and also adjusted in several approaches. Cold storage, in other words, is great, which has been in an unheated room for a long time needs additional examination of the pads and the brake system.

Another reason to think about the health of your vehicle and its mechanisms is the appearance of extraneous sounds. Any knock, creak or whistle indicates only one thing. not all bicycle systems work properly. As a rule, problems are related to the block or other mechanisms.

Brakes that do not respond well to the force you apply also indicate hydraulic or cable problems. Mechanical damage found during a visual inspection or after a collision must be repaired in a timely manner. Even if the brake system continues to function, one should not neglect its adjustment or replacement of individual components.

The open mechanism of the rim brakes greatly simplifies the procedure for their maintenance. Cyclists know how to set up rim brakes on a bicycle, but first you need to decide on the type of brake connection. Pads with V-Brake mount do not require special maintenance, basically manipulation with them is reduced to replacing worn-out elements.

A slightly outdated type is cantilever. Unlike the V-Brake, the mechanism of this attachment has a more complex device. There is an additional cable here, it is called the central one and is responsible for connecting both sides. Another characteristic difference is the large clearance. Bikes with this system are ideal for muddy riding.

The caliper brakes feature a U-shaped locking mechanism. A pair of levers are connected to effectively bite the rim. This is the most difficult type of mount and requires special skill to adjust it. Most two-wheeled vehicle owners are only familiar with the V-Brake type, as it is the most common.

When dismantling the brake system, observe the following sequence:

  • release the brakes and, using force, remove the cable jacket from the holder;
  • unscrew the mount, which is responsible for fixing to the frame;
  • directly remove the brake mechanism;
  • if it is necessary to replace the pads, unscrew the screw responsible for fixing them.

The last step is to remember the sequence of washers well. Usually they come in two, subsequent adjustment depends on their correct installation.

The rim brake pads are renewed or replaced depending on the degree of wear. For renewal, it is enough to degrease the surface of the contacting elements, and remove a small layer of rubber that has become unusable. For replacement, it is necessary to remove the fixing screw and pry off the old shoe and then replace it with a new one. Even if the new thing did not fit in size, do not rush to despair, the parameters are easily adjusted with a knife, provided that you are not holding a cartridge column.

After a successful replacement, you can start adjusting. The rim brakes are adjusted by changing the pad mounting geometry and cable tension. To do this, use a special screw, which is located on the brake lever. Excessive cable length can simply be cut. After replacement, new pads can move in any plane. The chock should be flush with the rim, this is the correct position. In the process of checking, special attention is paid to the position of the pads; when braking, it should fit snugly against the rim over the entire area, while driving, it should be parallel to the rim. If all points are observed, the screws are installed in their original position and a control check of the brake system is carried out.

It is more difficult to set up hydraulic brakes on a bike. They are practically not found in the modifications of the budget segment, rather it is a companion of a professional vehicle. The main feature of the hydraulic system is the use of brake fluid, otherwise working with it will not cause any particular difficulties. When starting to adjust the hydraulics, it is necessary to ensure that the wheel is evenly fixed in the position in which you move on it. This step is important for the hub and rotor. The brake adjustment is based on the caliper. First you need to loosen the bolts, the caliper should be movable, but not fall. Then squeeze the brake lever. the caliper will be in the desired position. At the final stage, you should check the clearances, tighten the bolts.

In addition to adjustment, the disc brake rotor needs to be replaced or straightened. If the defect is not strong, then replacement can be avoided by tightening the crooked place with an adjustable wrench. The disc mechanism is characterized by a high sensitivity to oily agents, therefore, cleaning and adjusting the system must be carried out extremely carefully. A small amount of oil left on the fingers can get inside. Use a degreasing product to adjust the rear brake of your bike. After partial disassembly, the chain is large and the carriage should be covered to prevent the ingress of oily liquid into the mechanism.

Adjust the position of the brake lever and the tension of the cable

To bring the brake lever closer to the steering wheel (for example, so that you do not have to stretch your fingers too much), tighten the bolt on the brake lever.

In this case, keep in mind that you should not bring the handle too close to the steering wheel. It should not touch the grip when fully clamped.

When the position of the brake lever is set, it remains to adjust the cable tension. The task is to bring the pads as close to the rim as possible, leaving a distance of 2-3 millimeters between the pad and the rim.

To do this, you can tighten the cable in two ways:

    For a rough adjustment, if the cable is very weakly tensioned, and the pads are far from the rim: loosen the bolt fixing the cable in the brake lever, tighten the cable, tighten the bolt.

When loosening the bolt, hold the lever and cable so that the cable does not run away and you do not have to re-thread it into the seat.

    for fine tuning, we use the adjusting screw at the point where the shirt comes out with a cable from the brake lever.

To make the screw spin freely, loosen the lock nut by unscrewing it counterclockwise. Turning the screw clockwise, we loosen the cable tension (the pads move away from the rim), unscrewing it counterclockwise, we increase the tension (the pads are closer to the rim). When the pads are in the desired position, tighten the lock nut.

That’s all! Checking how everything works. If necessary, readjust the springs of the levers (item 3).

Disc hydraulic brake

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

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

Adjusting the rear brakes on a bicycle

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

How To Get Power From Your Brakes | Mountain Bike Maintenance

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

Especially do not tolerate the striking of this element on the tire. A couple of kilometers. and the rubber will be frayed to holes. It is undesirable for the block to also go beyond the boundaries of the wheel. From this, it is quickly erased, but there is no desired 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 clamps, you should take only a hexagon. It is worth starting by holding the brake lever. This will push the pads against the rim. After examining the situation, you can immediately see where something is wrong. Use this tool to loosen the washer. Then, while still holding the brake lever, align the rubber clamp in the desired direction. The same is worth repeating on the other side. This is just the first step towards a perfectly tuned brake.

Setting up disc brakes

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

Experts recommend taking note of the following points:

  • If there are hydraulic disc brakes on the bike, then replacing the pads may not be necessary. they are able to do it on their own. But one nuance should be taken into account. if the hydraulic system is closed, then you will have to adjust the pads manually. for this, special valves are provided.
  • If you have to adjust disc mechanical brakes, 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 is 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 for a few meters and try to brake. If the cable is too tight, or the pads are too close to the disc, then too sharp braking will occur. this is a surprise in which the cyclist begins to move forward, but without his vehicle. Therefore, when driving for a test, you need to be extremely careful and careful, if necessary, the disc brake system is adjusted again taking into account previous errors.

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 in injuries.

Adjusting the front brake on a bicycle

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

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

Varieties and models of bicycle brakes

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

Setting v brake rim brakes

Today, mountain bikes are widely used with the v-brake system, so we will use this example to show you how to adjust the brakes of a bicycle in the case of a rim brake. Setting up other rim brakes is done in the same way. The only difference is that the bolts and screws that need to be 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.

Timely brake adjustments can help keep you out of trouble

The Case for Brakes

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

often than not, adjusting the brakes on a bike means placing the brake pads at the correct distance from the rim or disc and symmetrically to each other. Also, it may be necessary to tighten the cable or adjust the brake lever.

V-Brake. adjusting the brakes on a bicycle video

A small instruction on how to achieve this.

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

Actions to check and adjust the brakes

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

Adjusting and adjusting disc brakes on a bicycle video

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

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

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

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

Now you can go on a long and not only trip on your bike with pleasure.!

  • It is more convenient to set up and adjust the brakes if you have a rack (holder) for repair and maintenance of the bike
