Braking is provided by pressing the brake pads against a special track on the wheel rim. The most popular type of brakes today. Sufficiently effective brakes with excellent maintainability.
They differ in the way the brake pads are brought to the rim, but the principle of operation of different options for rim brakes is the same. Ideal for beginners: easy to set up, easy to adjust and very easy to repair in the field.
There are four types of rim brakes: caliper, cantilever, hydraulic and V-brakes. about each type:
- V. brake. When fully closed, the brake levers form a V. Best performance of any rim brake. The most demanded type and even overtake discs in popularity.
- Cantilevers are the prototype of V-brake brakes. Have been popular in the past. difficult to set up, with the advent of V-brake, have lost their relevance.
- Tick-borne. so called because of the levers, which resemble ticks in appearance. Today they are used only on road models due to the smallest mass. Less durable than other types due to only one attachment point to the fork.
- Hydraulic. the force from the brake lever to the brake pads is transmitted by a hydraulic line filled with a special fluid.
The advantages and disadvantages of all types of rim brakes are the same.
Disadvantages of rim brakes:
- Any particles or liquid trapped between the surface of the rim and the brake pads will reduce braking efficiency, accelerate pad wear, and in severe cases, remove chips and wipe the rim.
- May bend or spread the bike fork stays.
- Brake pads wear out pretty quickly. Fortunately, they are inexpensive.
- A bent rim greatly reduces brake performance and causes uneven pad wear.
Advantages of rim brakes:
- Light stress on the spokes and rim of the bike.
- Low price compared to disc brakes.
- Allows extended use of the brake, although may overheat the rim.
- Very light when compared to disc brakes.
- Easy maintenance and setup.
Drum brake for bike
Everybody knows the foot brake of a bicycle. this is the most popular brake on bicycles of the Soviet era. Even today it is the most popular single speed bike brake. The drum brake is located in the rear hub, the body of such a hub acts as a drum, and the pads are located inside. When the brake is applied, the pads are pressed against the inner surface of the hub and provide braking.
The brake drive can be manual, cable, or foot, pedaling in the opposite direction. The manual drive is practically not used.
Drum brakes have significant advantages and no less noticeable design disadvantages.
How to adjust the brakes on your bike
Drum brakes advantages:
- Powerful brakes with stepless deceleration control.
- Virtually sealed, requiring a minimum of maintenance.
- Do not wear out or place special requirements on the wheel rim.
Disadvantages of drum brakes:
- The main disadvantage is incompatibility with rear derailleur gearshift systems. Therefore, they are used on single-speed or bicycles with a planetary hub.
- Poorly cooled and even on small long descents lose efficiency.
- The braking force depends on the position of the pedal cranks in relation to the road. If the connecting rods are perpendicular to the road, the braking force tends to 0.
- Significantly load the hub and wheel spokes.
- If your bike’s chain has fallen off, then you lose the brakes. This is very dangerous and the drum brake must be duplicated with a rim brake.
- It is very difficult to actively pedal and still use the brake.
Like any other high-speed vehicle, a bicycle needs brakes. The safety of the cyclist depends on the quality of the brakes. It should be mentioned that track and some other models do without a mechanical brake system. The pedals are rigidly connected through a chain to the rear wheel hub, and braking is performed by slowing down the rotation of the pedals or by suddenly transferring the cyclist’s weight to one pedal, followed by blocking the drive wheel.
Anyone can understand that blocking has a negative effect on the condition of the tire, and the skidding movement of the wheel complicates the handling of the bike. For a sports bike, the absence of a brake is a way to reduce weight and increase the reliability of the structure, but riding such bicycles requires special equipment and will not add comfort to an ordinary person.
In general, the topic of choosing brakes is one of the most confusing and scandalous topics regarding the choice of bicycle components. Brakes differ in braking efficiency, maintainability, and durability. Many people with different experiences and needs are supporters of one design or another.
In the article, we will give an idea about the design of braking systems and mentioning the advantages and disadvantages of each, we will start the review with the least common. Even if you do not plan to service the bike yourself, you will need the knowledge to choose brakes to replace worn out ones or if old brakes cease to suit you.
Bike jog and roller brakes
Stiff brakes are reminiscent of train brakes: the brake shoe is pressed directly against the wheel tread. There is no need to talk a lot about the features of this system, since you will not find such a design on new bicycles for a long time. The speed brake is still used on bicycles in India and China. Fortunately, these models do not enter our market.
Roller brakes emerged as a result of the desire of one large manufacturer of bicycle components to make the perfect brake by removing the disadvantages of drum brakes (we’ll talk about them below). The brake hub was replaced with rollers, and the brake drum was fitted with a radiator for better cooling and removed from the wheel hub. The roller system does not require frequent maintenance and provides effective braking during normal driving. With a leisurely ride, these brakes serve for years without any adjustments. At the same time, in harsh operating conditions, roller brakes have no advantage.
Disadvantages of roller brakes:
- The largest weight of all braking systems.
- The complexity of the design and a considerable price.
- Most suspension forks do not support this type of brake.
- The brake does not block the rotation of the wheel in the opposite direction.
- The exclusive design makes it difficult to find spare parts, and there are no cheap consumables.
Roller brakes advantages:
- The rim geometry does not affect brake performance. “Eights” and “eggs” do not reduce the braking efficiency
- Excellent protection against dirt, dust and good water resistance.
- They require a minimum of adjustments and, with proper maintenance, are eternal.
- Almost the most efficient brakes.
Bicycle disc brakes
Disc brakes are the most modern brakes, rapidly replacing all other types. They consist of a brake lever, brake cable or hydraulic line, brake disc (rotor) and brake machine (caliper).
How to Adjust the Rear Brake Lever on a Motorcycle
The force from the brake lever is transmitted through a cable or hydraulic line to the brake machine. a caliper attached to the fork near the wheel axis. The caliper transmits force to the brake pads and compresses the rotor mounted on the wheel hub.
The advantages of disc brakes:
- Rotor and pads are high off the road and slightly dirty.
- Disc brake allows precise adjustment of the braking force.
- Wheel rim geometry does not affect braking performance.
- The rim does not wear out, with proper adjustment, the long service life of the mechanism.
Disadvantages of disc brakes:
- Brake pads from different brands are not compatible with each other.
- Overloading the wheel hub and spokes during braking.
- Repair requires qualifications and special tools and is almost impossible in the field.
- weight than rim systems.
- Good disc brakes are expensive. And cheap discs are inferior in efficiency to equal in price or cheaper rims.
- The caliper may interfere with the installation of a rear rack on a bike.
With all the variety of braking systems, the main competition today is between V-brakes and disc brakes. V-brakes occupy the lower price bracket, as well as the sports segment with stringent bike weight requirements. Although disc brakes are thought to be the future, rim brakes are still very good for normal non-aggressive driving.
You can buy bicycle brakes in Kiev with delivery in Ukraine from VeloGO.
Advantages and disadvantages of mechanical brakes
Mechanical brakes are cheaper, cables and sheaths (jackets), in which they are located, are quite reliable, more affordable than hydraulic mowing 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.
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 cable tightening. 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 for adjustment 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. The clipper is then correctly centered on the disc. 5. Only now we tighten the screws securing the brake machine to the adapter or plug. We act strictly one by one, 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!
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 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.
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 we 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 to 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 repairs the malfunction. 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.
How to adjust the brakes on a bike?
People who like to ride bicycles sometimes are not fully mastered in the correct adjustment of all important elements. Adjusting the brakes is one of the most important because it is one of the fundamental safety factors.
Cycling enthusiasts always carefully check the condition of the air pressure in the tires, gearshift adjuster, brakes and chain lubrication. In some cases, problems may arise due to the fact that it is not completely clear how to adjust the brakes on a bicycle.
While riding, you may find that the braking system has become less responsive to the actions of the cyclist. The reasons for this may be different, because the brake system of a bicycle consists of many elements that must work together harmoniously and their interaction must be clear. If the operation of the brakes lasted quite a long time, then you need to check the condition of the cables, brake levers, pads. The first step is to pay attention to things that are obvious and immediately catch the eye. The brake or lever mount may be loose. This is found when it is seen that the adhesion of the shoes to the rim of the wheel occurs after some stroke when the brake lever is pressed, and not immediately. This is the first possible type of problem to be dealt with.
To tighten the brake mount more, you need to adjust its position relative to the wheel rim, and tighten the nut to the end. The location should be symmetrical and the wheel should spin freely and not touch the pads. To properly secure the brake lever, you need to select the correct position for attaching the brake lever adjuster. To do this, properly tighten the cable connecting the handle and the brake clutch. After unscrewing the adjusting screw and pulling the cable more strongly, you need to fasten the lever and make sure that the tension is good and correct. You may not need to unscrew the cable screw, and you do not need to adjust the brakes if the brake levers are loose in the very mount to the steering wheel. In this case, you just need to tighten them harder.
Adjusting the brakes on a bicycle is also required if the bicycle stops too slowly when you press the brake lever. This means that the sensitivity is not set correctly. The same can be said if the braking is too harsh when the handle is pressed lightly. In this case, you need to unscrew the clamping bolt of the cable on the brake mount to the wheel. After that, it is necessary to put a sheet of thick cardboard folded in half between the pads and the rim. This is required to maintain symmetry and minimum clearance. Next, you need to pull the cable as tight as possible, but at the same time maintain balance so that the brake is not too sensitive when you press the lever. If the pads are worn out, then new ones should be purchased. To replace them, the clamping bolt of the pads is unscrewed, the worn ones are removed and new ones are installed. When the brake is applied, they should be pressed at right angles only to the rim and not touch the tire. By tightening the clamping bolt, you can actually test the operation of the brake.
It is much easier to adjust the brakes on a bicycle if they are of the type of internal or so-called drum brakes. They are much more stable and require only loosening or tightening the adjusting nut to adjust. In the worst case, you will have to unscrew the rear wheel, remove it and deal with the condition of the pads inside the wheel axle. If they become unusable, you will have to make a replacement. Otherwise, the brakes can completely fail while riding. If the bike has disc brakes, then the process of adjusting them is similar to the first one, because you will also have to tighten or relax the cables, but there are much more steps, since you will also have to adjust the gap between the brake pad and the disc, align the brake with the disc. In addition, there are three types of disc brakes and for each of them you need to know about the specific nuances of adjustment and tuning.
Nevertheless, such adjustments happen very rarely, because the brake systems of bicycles work well for a very long time and there are no serious problems with them for a long time. In addition, the entire adjustment process takes an average of 10-15 minutes to bring all the brake elements into line.
How to check and adjust the brakes on a bicycle, useful tips
8 minutes 312 Schematic illustration of rim brakes
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 attached to 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 mounts 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 are in contact with the rim.
- Responsible for unclamping is an elastic metal insert or spring built between the levers.
The levers have a single axis of 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.
Tick on the front wheel of a road bike
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. The principle of operation of the cantilever brake:
- 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 attached to the frame.
- Due to the convergence of the levers, the pads approach the rim.
The cantilevers are dirt resistant, will not bump the tire and are easy to install. Significant disadvantages include:
- decrease in braking force as the leash is pulled;
- you need to create a high effort to stop the bike completely;
- difficulty of adjustment.
In justification of the latter, it should be noted that the position of the pads can be adjusted within wide limits.
The top link cantilever can also be fitted to the front wheel as an optional extra
V-brake is a common type of rim brake on high-speed bicycles. Compared to cantilevers, it has a higher precision and longer shoe longevity. They are also easy to remove and repair yourself.
The vectors are partially similar in design to cantilevers: the front brake levers are bolted to the fork, the rear brake levers are attached to the upper stays. The legs are connected to each other by a pulling cable. The drive cable is brought to one side, but due to the straight shape of the “tie” forces are equally transmitted to both levers.
V-brakes are popular on MTBs
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. Those, in turn, move the pads towards each other.
Advantages. high compression force and efficiency, excellent modulation. Disadvantages. deterioration of work with a blockage of the hydraulic line, complex repairs. Used a similar type of brakes for freeride and trial.
Rim-type brakes have low brake pad travel, which means they wear less during operation. A significant disadvantage of this approach is the inability to be 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.
- Attach the levers to the bike frame.
- Insert the drive cable into the brake lever.
- Install the handle on the steering wheel, insert the cable into the grooves on the frame (if any).
- Connect the cable with the levers and put the spring.
Brake pad mounting diagram
If your bike has cartridge pads, you only need to change the pads. Their position is set with a cotter pin; before removing the old surface, it is removed from the body. Similarly, in the reverse order, insert a new pad and fix it with a cotter pin.
Adjustment of the position and displacement of the shoe housings are carried out by means of a bolt and washers. For accurate fixation, you need to squeeze the brake and set the position of the pads strictly on the surface of the rim.
The last step will be to test the operation of the system in practice, that is, in real driving conditions. As a rule, the V-brake setting is obtained immediately. However, if braking is delayed or the handle does not fully return to its original position, the brakes must be readjusted.
You can also read about similar topics: Adjusting the hydraulic brakes of a bicycle and replacing the pads Correct adjustment of the brakes on a bicycle How to change brake pads on a bicycle?
First step. Adjusting the brake levers
Brake levers should be located so that they can be reached quickly and comfortably. In order to adjust the position of the brake lever, loosen the fastening screw, place the handle as it is convenient for you and fix it. Usually there is a screw on the brake lever, with which you can adjust the distance of the brake lever to the grip. adjust the position of the lever with it.
Second step. Position of the brake pads
It is easier to adjust the position of the brake pads as follows: press one of the pads with your hands close to the rim, adjust its position. Make sure that the block is not too low (the edge of the block is below the rim), but also not too high. the block touches the tire.
I would like to draw special attention to the next moment, since there is little clear written about it. Until the nut of which the shoe is fixed is not tightened, the shoe has three degrees of freedom: the washers form something like a ball joint. (Pay attention to how many washers are there? That’s what they are for!). It is believed that the leading edge of the pads should touch the rim slightly earlier than the rear. Therefore, we do this: put a small gasket under the rear end (see fig).
This number of washers is needed to get something like a ball joint
Now you can tighten the nut that fixes the shoe.
Step three. Centering the positions of the levers
At this step, you need to fix the brake cable: so that the brake pads touch the rims at least a little if you press the brake lever. At the bottom of the levers there are special bolts that adjust the tension of the springs that press the pads against the rim.
We set it up as follows: press the brake and see which of the pads touches earlier. For the one that touched earlier, we increase the spring tension (or vice versa, weaken it on the other side). It is necessary to ensure that the pads touch the rim at the same time.
Fourth step. Adjusting the distance from the pads to the rim
I believe that this distance should be as small as possible. (1-2 mm. If the rim is even). But then the brakes will work very sharply. the slightest pressure leads to sharp braking. Therefore, the distance can be made a little more.
The distance is adjusted in two steps: first, due to the screw with which the cable is attached to the brakes. Then fine tuning on the brake lever.
The large washer acts as a lock: when it is tightened, the cable tension adjustment screw cannot be turned.
Today we will learn how to set up V-Brake brakes, which are otherwise known as linear brakes. For this job, you will need a 5mm Allen key and a Phillips screwdriver. For a better understanding of how to set up V-Brakes on a bike, see the pictures that show all the steps in order.
Loosen the anchor bolt.
Loosen the fixing bolt, as a result, the brake cable will slide as shown in the figure to open the brake
Align the brake pads parallel to the rim
Connecting the cable to the brake lever
Route the cable with the brake cable and tighten the anchor bolt
Compress the brake caliper and firmly fasten the cable as shown in the figure, observing the sequence of actions.
Perform Bike Brake Test
Adjust cable tension if necessary
Repeat all steps to adjust the front and rear brakes of the bike.
Opening and Closing V-Brakes for Wheel Removal
Squeeze the brake caliper and pull the brake cable (left and up as shown)
Spread the unlocked brake pads to the sides
Repeat the reverse steps to close the brake.
I recommend that you release the brake when storing your bike for a long time. This will increase the service life of the brake springs.
If you still have difficulty in adjusting and adjusting your V-Brake bike brakes, then check out this.
Rim brakes have a very simple principle of operation. two brake pads installed opposite each other and parallel to the wheel, and between them a rim. Pressing the brake lever, the force is transmitted through the system of cables and shirts to the brake levers, which press the pads against the wheel rim, stopping it.
For smooth operation of the rim brakes, you need to monitor the integrity of the cable and the absence of “eights” on the wheel. If at least one fiber is broken on the cable, it must be replaced. The cable should move freely in the shirt and if it gets stuck it is necessary to change either the cable or the shirt.
The main thing in the high-quality operation of rim brakes is the high-quality pressing of the pads to the rim. This can be adjusted by fastening the pads. The fastener consists of a set of washers, gaskets and a nut, it allows you to fix the shoe at the desired angle.
To adjust, loosen the nut on each shoe slightly so that the shoe can be moved with your fingers, but it will not move. Place the block parallel to the wheel rim, note that it must not touch the tire (the distance between the block and the tire must be at least 1 mm.).
- If you have soft rubber brake pads, they will deform when braking. Therefore, they must be installed so that the leading edge of these pads is 1 mm. closer to the rim than the rear. To do this, place a 1-1.5 mm thick gasket under the rear parts of the pads before adjusting. For example, a piece of rubber cut from a worn bicycle tube.
- If you have brake pads with a rigid base that do not deform when braking, you must install strictly parallel to the rim.
Then firmly press the brake lever and tighten the nuts on the pads, carefully watch that they do not change their position at the same time.
Then look at the brake levers. Squeeze and release the brake levers several times, the levers should converge and diverge equally. This can be adjusted with the spring tension screws located at the base of the lever. We turn the adjusting screw on the lever that deflects too little, and unscrew it if the lever deflects too much.
In order to remove the wheel, you do not need to unscrew the brake cable, you just need to release it from the clamp. To do this, squeeze the brake levers with your hands and remove the rigid part of the cable jacket from the slot.
Setting the brakes
Setting up bicycle rim brakes type V-brakes
We recommend replacing the pads based on the condition of the dirt drainage grooves. Rim brakes are sensitive to dirt, if dirt is no longer removed effectively, the braking power drops significantly.
By how symmetrical the wear of both pads is, you can determine the correct installation and adjustment of the brake. If the working surface does not wear evenly, it is necessary to adjust the pads.
Loosen the screw holding the brake cable, spread the brake levers. Even without removing the wheel, you will have easy access to the pads.
Remove the old pads and install a new kit. Do not interfere with the installation sequence of the washers used to adjust the position of the shoes.
The adjusting drum, installed on the brake lever, at the point of connection with the cable, must be screwed in until it stops, and then unscrewed one full turn. In the future, this will be needed to fine-tune the position of the pads.
Install and secure the brake cable. The distance between the pads and the rim must be 2mm.
Place the pads parallel to the rim. A pair of spherical washers will allow you to adjust the angle of the pad in all planes. The pads must be installed without skewing, leading to uneven wear.
Press down firmly on the brake lever, pressing the pads against the rim. In this position, tighten the nuts of the fixing shoes.
Apply the brake several times while watching the brake levers come together. They should move symmetrically, pressing the pads against both sides of the rim. If this does not happen, adjust the position of the levers using the adjusting bolts.
Setting up mechanical disc brakes
Mechanical disc brakes are a simple and reliable system often found on bicycles of all price categories. Unlike rim brothers, they are not afraid of dirt on the working surface of the disc, developing maximum braking force in any conditions.
A pair of brake pads is installed in the caliper, one of which is pressed against the brake disc when the brake lever is pressed. The second is motionless. Its position is set with a hex wrench or manually.
Fully screw in, and then unscrew one full turn, the drum located at the junction of the brake cable and brake lever. This will be required to further adjust the brakes.
After loosening the mounting bolts, find the position in which the pads are parallel to the surface of the brake disc, observing the ratio of the clearances shown in the figure:
Install and secure the brake cable to the caliper. Adjust the position of the fixed shoe using a wrench or manually.
If necessary, adjust the position of the movable shoe by changing the tension on the cable. This can be done by rotating the drum on the brake lever. During operation, when the pads are worn and the cable is stretched, tighten the drum, keeping the minimum idle speed of the brake lever.
Setting up hydraulic disc brakes
The most modern type of bicycle brake, previously only fitted to professional bicycles, but now widely used. Unlike mechanical brakes, the hydraulics are easy to install and maintain, and the absence of a stretch cable eliminates the need for frequent adjustments.
To adjust the hydraulic brake, loosen the bolts holding the caliper on the bike frame and press the brake lever firmly several times. Evenly extending pads will center the caliper in relation to the brake disc. Without releasing the handle, tighten the mounting bolts.
The distance between the pads and the surface of the brake disc must be the same on both sides. If one of the pads extends further, loosen the fixing bolts and manually adjust the position of the caliper. Uneven pad coming out is usually associated with dirty brakes and can be observed with prolonged use. In this case, we recommend cleaning and maintenance of the brake at a bicycle workshop.
