Adjusting the brakes on a bicycle disc mechanical

Setting up disc brakes

adjusting, brakes, bicycle, disc

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.

How To Adjust Mechanical Disc Brakes by Performance Bicycle

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 there is one caveat to Honor. if the hydraulic system is closed, then you will have to adjust the pads in manual mode. for this, special valves are provided.
  • If you have to adjust disc mechanical brakes, 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 was overtightened, 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, during a test drive, you need to be extremely careful and careful, if necessary, the disc brake system is adjusted again taking into account previous errors.

Adjusting hydraulic disc brakes

Hydraulic bike brakes are positioned as self-adjusting, requiring no intervention or adjustment. But you still need to set them up from time to time. For example, if you hear strange creaks or rustles during operation, or the factory settings are initially incorrectly set. The following few steps will help you quickly and efficiently set up your hydraulic disc brakes:

  • The bolts fixing the caliper on the adapter must be loosened.
  • Squeeze the brake lever and fix it in this position (if there is no assistant, use the materials at hand: electrical tape, fishing line, wire).
  • We carry out a visual inspection. As with a mechanical system, the rotor should be positioned clearly in the middle of the caliper slot, with pads equidistant from it. If the rotor is not positioned correctly, align it by pressing in the direction where the unevenness is noticed. This will contribute to an even distribution of liquid and fixation in the desired position of the pads and rotor.
  • At this point, the adjustment can be considered complete, and you just have to fix the mounting bolts and return the handle to its original position.

As with mechanics, hydraulics also have a rotor that performs the same function. Sometimes it can give in to deformation. But this can be eliminated by determining the place of the bend and bending it in the opposite direction. Then the shuffling sounds when driving will stop.

Adjusting the rim brakes

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

Note: it is important to observe three main rules:

  • the pads should be parallel to the rim;
  • the gap between the rim and the block should not be more or less than 1 mm;
  • the pads should be symmetrical with respect 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 shoe touches the rim. By releasing the brake lever, the shoe can be set to the desired position. it moves up, down and at an angle.
  • The distance between the 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 specific vehicle can be obtained either from the instructions for it, or on the Internet for technical characteristics. It should be for Honor that the wheel should be braked even with the smallest pressure on the brake lever. That is, if the wheel stops only when the brake lever is fully pressed “all the way”, then this is incorrect.

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

Disc hydraulic brakes

In such a case, the reason for the adjustment is the strong resistance of the wheel at the moment of movement, as well as when an extraneous sound or squeak appears.

The adjustment instructions in this case are as follows:

  • On the caliper, the bolts are unscrewed, after which the handle is squeezed out to press the pads against the wheel.
  • The next step is to check the position of the valves. They must be equally spaced from the rotor.
  • Next, all screws are tightened.
  • After locking the caliper, the handle is released. In this position, the block should not be pressed against the rim, be at a distance of about a millimeter.
  • Quite often there is a situation where the pads are located at different distances from the rim. The problem can be solved by pressing one of the pads, after which the handle is worked through 10 times. Due to such actions, unevenness is eliminated.

The final stage involves setting the correct position of the handle, which controls the system. For this, a special adjusting hexagon is installed.

Adjusting and adjusting disc brakes on a bicycle

Despite the fact that the design is quite simple and reliable, it has to be adjusted from time to time.

This is done for the following reasons:

  • To ensure long-term performance.
  • High efficiency enhancements.

Disc hydraulic brakes

Hydraulics are used to create a wide variety of mechanisms. Its high efficiency is primarily due to the non-compressibility of the liquid.

The following points are called features:

  • The main advantage is the ease of braking and the softness of the system used. In this case, you can feel the pressure force, which increases towards the end of the handle stroke. In comparison with the mechanical type of the device, the considered one is characterized by a smoother stroke of the handle. Therefore, there is no need to apply a lot of force for braking.
  • The hydraulics can withstand long-term use. This is due to the fact that it is less prone to overheating. Therefore, braking can take place for a long period even when driving downhill.
  • Device adjustments are carried out much less frequently. That is why you can remove the wheel for cleaning or replacing it.

Mechanical disc brakes

Mechanical brakes are recommended to be adjusted in case the disc rubs against the pad. In addition, adjustment is required in the event of a weakening of the braking force.

Instructions for setting up mechanical disc brakes are as follows:

  • The brake lever is squeezed out to the stop.
  • The lock nut of the machine is unscrewed, after which the regulator is turned inside out. If you need to unscrew it strongly, then you have to loosen the cable.
  • Determined what the gap between the disc and the pad. If the braking device is crooked, loosen the screws to adjust the position. They attach the device to an adapter or plug.
  • The screws that secure the brake are unscrewed.
  • Having made the caliper movable, the handle should be squeezed out to the end, after which it should be fixed in this position. Next, the correct centering of the machine relative to the disc is carried out.
  • Tightening is carried out with a screw to fasten the brake machine. Twisting should be carried out periodically, since only in this case it is possible to exclude the possibility of shear.

After that, the handle is released. Compliance with the recommendations specified in the instructions ensures the ideal position of the disc and pad.

Bicycle disc brake design

In many ways, it is the design of the disc brakes that determines how tuning is done.

All devices fall into two categories:

  • The mechanical device has a cable, due to which energy is transferred from the handle to the executive unit. In this case, a high force can be transmitted.
  • Hydraulics are represented by the line through which the fluid transfers energy to the brake pads.

How to set up and adjust disc brakes on a bicycle

New bicycles are often equipped with rim brakes, or V-brakes, and Soviet bicycles have always been fitted with the only existing caliper brakes. Currently, this is due to the desire to reduce the cost of the design: it is no secret that many cyclists dream of changing the brakes to disc brakes as soon as possible. Often, even when choosing a bike, the costs for changing the brake system are included in the amount.

Below we will show you how to set up disc brakes on your dream bike.

Since the principle of operation of disc brakes is different, it is impossible to adjust them according to the same scheme. Brake disc mechanisms are:

  • mechanical. In this case, the braking energy is transmitted mechanically, using a cable;
  • hydraulic brakes, which have a specially laid hydraulic line, and the braking energy is transmitted by the pressure of the liquid column.

Advantages and disadvantages of mechanical brakes

Mechanical brakes are cheaper, cables and casings (jackets), in which they are located, are quite reliable, more accessible than hydraulic lines. It is also important that the repair of a mechanical brake in the case of a bent disc is easy to carry out on your own.

Advantages and disadvantages of hydraulic brakes?

The main advantage, of course, is easier and more comfortable braking due to the “soft” pressure of the liquid column, the “feel” of the handle and control over effort. The hydraulics are more durable with long braking distances, as they are less prone to overheating. Also, these brakes can be adjusted much less often than mechanical.

A significant drawback of liquid-based braking systems is damage (breakthrough) of the hydraulic line, when service is indispensable.

Mechanical disc brake adjustment

It is necessary to adjust the mechanical brakes when the disc “shuffles”, rubs against the pad, or when the braking has become weak.

We start with the brake lever: squeeze it to failure. If it reaches the fingers, then we begin to limit its free travel: we loosen the lock nut of the machine and turn the regulator out, then tighten the lock nut and check the handle stroke. If you need to unscrew the screw too much, then first loosen the tightening of the cable. To do this, unscrew the caliper swingarm screw, and after you pull out the cable, turn it back on.

We estimate the gap between the disc and the pads. it is better for the light and against a light background so that it is clearly visible. The illustration on the right clearly shows that the brake machine itself is crooked, and to adjust, we loosen the screws that attach the brake to the fork or adapter.

After that, loosen the screws so that the brake moves freely.

After the caliper has become movable, it is necessary again, as at the very beginning, to “squeeze” the brake lever and fix it in this state by tying it to the grip with a strip of fabric or an elastic band. After that, the machine gets the correct centering on the disc.
5. Only now we tighten the screws securing the brake machine to the adapter or plug. We act strictly one at a time, screwing in the screws equally, at 25% of the turn. After that, release the handle.

After these measures, we get a perfectly uniform mutual position of the disc and pads, without distortions. Setup finished!

Setting up the hydraulic disc brake

The reason for tuning, as always, is resistance to wheel movement, as well as extraneous sounds, for example, creaking and rustling. Do not forget about a simple check: a suspended and spun wheel quickly stops if the pads touch the brake disc.

  • We loosen the bolts on the caliper so that it is movable, then squeeze the brake handle so that the pads are pressed against the rotor
  • Now it is worth checking the position of the valves on the pads so that they stand symmetrically and equally from the rotor.
  • Now you need, without releasing the handle, tighten all the screws on the caliper.
  • We release the handle, check the operation of the mechanism. In the best case, the pads from the disc should be at the thickness of the hair, but not touching it.
  • If the pads are still located at different distances, but at the same time the rotor is ideally placed in the machine, then you can do this: press the disc against the pad that protrudes more strongly, and work sharply with the brake handle about 10 times. The unevenness of the valve aligns the pads, and the malfunction is corrected. It is better to do this together: the assistant presses the disc to the block with both hands, and the other squeezes the handle.
  • At the end of the setting, we set the brake lever correctly using the adjusting hexagon. The main thing to remember here is that moving the handle closer to you simultaneously brings the pads closer to the rotor and vice versa.

Let’s say that whatever brakes you choose, you should always be confident in them. And only when all your orders the bike will execute flawlessly, you will get real pleasure.

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 yet completely erased and, as a rule, disc brake pads take longer to wear than rim pads. 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 on the disc. After all, the gap of 0.3 mm 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 there is a rack (holder)

How to set up disc brakes on a bicycle, set the brake pads correctly

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 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 1mm. And both pads must be symmetrical.


Replacement of pads is made when their surface is erased to the level of grooves for outflow of dirt (available on all v-brake pads). Those. the working surface becomes completely flat. over, if this happened only from one edge of the pads, this indicates that they were incorrectly installed. And again they need to be replaced.

Open the brake by bringing the brake levers together with your hand and removing the metal arcuate end of the shirt from the groove, from which the cable comes out (see picture)

How To Change & Adjust Mechanical Bike Disc Brake Pads

If you put on simple new pads, then the main thing is to put on in the required sequence all the gaskets and washers that make up the pads fasteners (see the picture) And it is better if you write down or sketch the sequence in which you had them. Sometimes the pads are left and right. This is always indicated on the pads themselves. Do not confuse!

The cartridge pads are even easier to change. They have a metal base and only the rubber pad changes. To do this, remove the locking cotter pin that secures the pad in the shoe and slide out the rubber pad. Do not lose the cotter pin, it does not always come with new pads. Insert new pads and secure with a cotter pin. Do not confuse left and right (see picture) Otherwise you will not be able to fix them.

After replacing pads, the brakes need to be adjusted.

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 activated, congratulations! You did everything right!

Successful rides for rim brake owners!

Actions to check and adjust the brakes

  • Determine the type of brakes. disc, rim or other option.
  • Raise the front wheel, spin it up and press the left brake lever. If the wheel has stopped, then most likely the brake is working properly. But if at the same time the brake lever touches the steering wheel, then you need to pull the cable. We do the same with the rear wheel.
  • In order to tighten the cable, shaped bolts are provided on the brake lever. Try to twist them. if the cable requires a little adjustment, this should be enough.
  • If this does not help, then you need to tighten the cable. The cable in the brake lever is inserted into a special slot; at its end there is a cylinder of a larger diameter, for which it is held inside the handle. Therefore, it is tightened in the brake itself. See where the end of the cable is on your bike. The cable is obviously longer than the required length, so its end from the side of the brake is always visible. Sometimes it is even reeled up. We look at which bolt holds your cable, loosen it and tighten the cable with pliers. Tighten the bolt harder to tighten the cable.
  • If everything is in order with the handles, check the brake pads. (You can check the pads first and then the handles)

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


The principle of operation of rim brakes is clear, I think to everyone. 2 brake pads located opposite each other parallel to the wheel, between them there is a rim. When you press the brake lever, the pads compress the rim, stopping the wheel. The mechanism is driven by a cable pull.

In order for the brakes to work without failures, you need to monitor the integrity of the cable. If its braid is loose somewhere or at least one fiber breaks, the cable should be replaced. It is important that the cable runs freely in the shirt. And make sure you don’t have eights.

The basis for good brake performance is the correct pressure of the brake pads against the wheel rim. This is regulated by the pad fasteners, which consists of a set of aluminum spacers and a nut on the axle. This kit allows you to fix the last at the desired angle. And to do this, you need to loosen the nut on each pad and firmly clamp the brake. Position the pads so that they are horizontal, touching the rim with their entire surface, but not touching the tire (see picture). And carefully shade the nuts without knocking out the position of the pads. This is true for cartridge pads. For ordinary pads, the rear part of the pads must first be pressed against the rim horizontally (see below). In addition, you need to watch that the brake levers converge in the same way. This is adjusted by the Phillips spring tension screw at the base of the lever.

If when you press the brakes one lever moves weakly, then the screw on this lever should be tightened a little, too easy. unscrew.

Repair, adjustment and adjustment of brakes on a bicycle with your own hands

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.


About bicycle disc brake repair

Setting up and installing hydraulic brakes on a bicycle is done in a different way, you can learn more about this here.

? Find out how to get rid of this problem:

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, which is held by a leash (jacket);
  • cantilever. with an additional central mount, from 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. These models are the hardest to weaken.

Each type is understood differently, but the overwhelming majority will only have to deal with the first type.

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” and from frost during storage, as well as from heating during active braking.

Less often, replacing the shoe is done. After unscrewing the screw, the old shoe is pry off and removed, and a new one is installed in its place. Here, accuracy is required when choosing, since there is no single standard, and the groove for the screw may not fit, and the shoe itself on the site may not lie. Fortunately, any sizing problem is dealt with with a sharp knife. In the case of a cartridge shoe, undercutting probably won’t help, but such cases are quite rare.

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 pads fixing screw, if work with pads is required.

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.

Symptoms of problems

How do I know if my bike needs a 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 your bike for more than a month. especially if it was cold storage, maintenance of the pads and the brake mechanism is imperative.
  • “New” sounds are heard from the mechanism: humming at speed, periodic knocks, whistles, squeaks. problems with mechanical parts or a block.
  • The brakes began to react poorly to effort, that is, they only work after a certain stroke, do not immediately “release”, etc. a clear sign of problems with the cables or hydraulics.
  • Visual damage to the cables or elements of the brake mechanism. they can continue to work, but it is simply necessary to adjust after, for example, an impact.

Basic nodes to check

Things to check before adjusting disc brakes?

  • Handle position. Its customization for hydraulic mechanisms is also available.
  • Rotor if damaged or damaged. If there are chips, then no adjustment will help.
  • Transmission status (cable or channel)
  • Pads in a brake machine (caliper).

The hydraulic drive is a rare guest in budget models. It is still used mainly by professionals. Adjusting the brakes on a hydraulically actuated bike is not very different from mechanics and can be tackled. Unlike mechanics, hydraulics require work with brake fluid. Especially in winter, when it is necessary to bleed it to increase the stroke of the pad.

There are other problems in mechanics. There it may be necessary to adjust the pad pressing angle. As with the rim versions, it must be strictly parallel to the rotor. This increases the life of the brake system.

Disc brakes have to be adjusted at the caliper. Adjustment steps:

  • We fix the wheel exactly in the same position as we will drive. This is important for the position of the hub and rotor.
  • We loosen the bolts that fix the caliper literally by a millimeter so that it can move, but not fall.
  • Squeeze the brake lever. The caliper falls into place.
  • Checking the clearances after releasing the brake lever.
  • We tighten the bolts or move the brake machine.
  • If the machine no longer moves freely, we work with the bolts one by one, displacing it by tension of one or the other bolt.

Tension adjustment

The distance from the shoe to the rim is adjusted through the tension of the cable. There is a screw for this, which is located on the brake lever. When it rotates, the pads, respectively, approach (counterclockwise) and move away (clockwise) from each other and from the rim.

If the adjustment of the screw is not sufficient, you will need to shorten or lengthen the cable. This is done on the brakes themselves. Opposite the shirt, on the opposite element, the cable is clamped 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 breaks, although practice shows that such “reserves” do not help anyone.


V-Brake adjustment consists in changing the geometry of the pads attachment and the tension of the cable.

Find your sport

Modern bicycles are equipped with disc or rim brake systems. The most common problems requiring adjustment are the adjustment of the position of the brake pads, and the gap between them and the braking surface. The brakes are adjusted on the pads themselves, and by adjusting the brake lever.

Adjusting the brake on a bicycle is a rather rare procedure, which is necessary in rare cases, mainly due to wear or damage to the bicycle components. So, for example, if the rim is damaged, the pads will cling to the disc or rim, and when the pads are worn out, the distance to the disc will become greater, which will not allow effective use of the brake. It is important to understand that well-adjusted brakes are the key to safe driving.

Adjusting disc brakes

Pads on disc brakes wear less than pads on a bicycle equipped with a rim braking system. Braking with disc brakes can be more effective than with rim brakes, but in the same price category, v-brakes can be more practical and more effective than disc brakes.

The position of the shoes is adjusted using the adjusting bolts. The distance that must be set between the pads is within tenths of a millimeter. The pads, as in the case of rim brakes, must be installed symmetrically relative to the disc, and are located at the same distance relative to it. After setting the gap, it is necessary to check that when the wheel rotates, the pads do not come into contact with the disc. The correct setting of the gap must ensure timely brake engagement. To achieve the most effective braking, the brake lever travel should not exceed half the distance to the handlebar.

After checking the disc brake setting with the raised wheels, a small test drive should be done. In this case, you should act carefully, gently pressing the handles. If the braking is not effective enough, the cable should be tightened, this is done in the same way as when using v-brake.

Rim brake adjustment (V-brake)

The most common braking system using rim brakes is called v-brake. Other systems work on the same principle, the differences will be extremely constructive, and quite insignificant. Therefore, the approach described below is suitable for all rim brake systems.

By adjusting the v-brake of the system, it is necessary to achieve a minimum clearance between the shoe and the rim. Pads must be aligned symmetrically and parallel to the rim.
The procedure is as follows:

  • The pads must first be installed parallel to the rim. For this, the hex nut is loosened, which is responsible for fixing the pads. To understand how you need to install the shoe, you should press the brake and see how the unfixed shoe contacts the rim, then, releasing the brake, proceed with the adjustment. Adjustment allows you to position the pads at the desired height and turn them to the desired angle, which will achieve the best position for effective braking.
  • With the pads correctly installed in relation to the rim, it is necessary to adjust the clearance. The distance to the rim should be as small as possible so that the slightest effort on the brake lever is already braking. In this case, it is necessary to check that the gap is not too small, and the pads do not wear off during normal driving. When the wheel rotates, without the correct spokes tension, the wheel will rotate with a small figure eight, so often setting the gap is a rather delicate procedure.
  • The last step in the setup is to check the brake adjustment. First, the check is carried out with the raised wheel, then it is necessary to test them on the go. If you do not hear any extraneous noise, when braking, the position of the handle does not exceed half of its travel to the steering wheel, then all work on adjusting the brakes was performed correctly.

Checking the tension of the cable

Insufficient cable tension is characterized by the position of the brake lever at which braking begins. You can check this on the go, or by lifting the wheel, untwisting it and pressing the brake. The sooner the wheels stop when pressed, the faster the bike can stop.

If, during braking, it is possible to press the brake lever more than half the distance to the steering wheel without much effort, you must tighten the brake cable. A slight tension in the cable can be pulled on the brake lever using a figured bolt.

If the handle is easy to push all the way to the handlebars, pull the cable from the side of the brakes themselves. The cable is attached to the brake with a special screw. To tension the cable, it is necessary to unscrew this screw, tighten the cable with pliers, and fix it by tightening the adjusting screw tightly. As a rule, when fixing the cable, a small tail remains, which should not be too long. To prevent the cable from getting into the wheels or other bicycle systems, the excess part of the cable must be wound or cut off, leaving a small margin, not exceeding a few centimeters.

Adjusting the brake pads

A braking system using disc brakes is structurally different from a rim brake system, therefore, setting the pads for both systems should be considered separately.

Installing disc brakes on your bike

When the brakes on the bike are already very worn out, or they are not satisfactory in their characteristics, it is not necessary to buy a new bike. With sufficient desire and opportunities, the installation of better brakes is a completely solvable task. Of course, it will be much better to solve it if the design of the bicycle allows it to be done without significant costs.

If the current braking system is in good condition, you can choose an option that will save on brake levers and cables. If the condition of the brakes is in doubt, it would be better to replace all elements of the system with new ones. In the case of installing hydraulics, without options, you will have to replace the entire system as a whole, and additionally solve the issue of laying hydraulic lines. Old brakes should not be thrown away, especially if the bike is being used for long journeys. In the event of a breakdown, they can do a good job.
