Types and characteristics
Rim brakes have come a long way during their evolution. They have come down to us in the form of pliers, cantilever, V-brakes and hydraulic systems. Each type has its own specific features, advantages and disadvantages.
Adjusting the brakes on a bicycle
You suspect a malfunction of the brakes on the bike, strange sounds arose during braking and when you press the handle, the stopping mechanism does not work at all or works slowly, which means there is a need to adjust and adjust the system.
- You need to start with the handle: when it is fully pressed, it should not reach the fingers of the hand, if, on the contrary, then you need to adjust with the lock nut.
- After we assess the backlash between the disc and the pads. you can put a light sheet of paper for a more visual adjustment, release the screws that attach the brake to the fork or adapter.
- Next, loosen the screws for free wheeling of the brake.
- As a result, the caliper has become a movable structure. Now you need to push the brake lever so that the pads are pressed against the rotor. In this position, the caliper is centered.
- Finally, attach the connecting screws to the adapter or plug. We carry out clearly alternately, screwing the screws in the same way, by 1/4 circle. Then the handle can be loosened.
- Only if the caliper device is reliable, the handle is working properly, there is no distortion of the rotor design, as well as worn pads, all the previous recommendations for adjusting the disc brake on a bike will give a result.
The appearance resembles a tick, with a similar working principle. The brake levers are in an X-shaped connection and are attached to the base frame at one point. Simplicity of design and easy setup do not bring this model to the top of popularity.
The reason is the unreliability of the design and the relatively large weight. If lumps of dirt get in, misalignment, or deformation of the rim, the levers are skewed, which causes a number of additional problems. Including increased friction of the pads, and their premature wear. No less significant drawback. certain restrictions on the use of tires with a wide profile.
If the pistons extend the pads unevenly
If one piston does not work freely, it is most likely clogged. In this case, it is worth removing the wheel, and then removing the pads from the caliper. You will need a clean metal plate with holes for the mounting pins.

Using it, move the serviceable piston and press the brake lever so that the clogged one can get out. After that, it is necessary to wipe it with a clean cloth and apply mineral oil (non-aggressive to rubber) on its surface. Then put the piston back, wiping off excess oil. often the rear brakes on the bike get dirty, probably due to the fact that there are more mechanical parts and the drive.
Comparative advantages of v-brake:
Unpretentiousness, relatively simple installation and configuration. 2. Affordable price, especially when compared to hydraulic disc systems. 3. Simple lightweight design that reduces the overall weight of the bike. May be relevant to competition in certain sports disciplines. 4. Sufficiently powerful brake fixation. 5. Affordable offer of pads and spare parts, which facilitates maintenance, partial or complete replacement and repair.
Disadvantages of v-brakes:
High quality wheel assembly is required. In the presence of an eight, efficiency is significantly reduced. The large range of curvature prevents the pads from evenly contacting the rim. As a result, excessive friction can arise, which prevents the wheel from fully rotating in free mode. If the gap between the pads and the rim is made excessive, then the power of the friction clutch may be insufficient to create the necessary braking effect. 2. When moisture gets on a metal rim (without a ceramic coating), v-brakes become less effective. the pads slip along the rim with an unpleasant sharp sound. 3. The friction of the pads on the rim with the prevailing extreme movement is capable of wiping the metal of the rim to a state of disrepair in a fairly short time. 4. Due to the proximity of the road surface, when driving on the pads and on the rim, dirt particles get abundantly, which accelerates the wear process. 5. During prolonged descents, as a result of constant friction, the rim is critically heated, which can affect the integrity of the tire (in the areas of direct contact with the rim). 6. The distance between the pressure arms provided by the v-brake design does not allow for the installation of ultra-wide tires for extreme driving conditions.
Replacing the drum brake
The most complex mechanism is drum brakes. To replace them, the rear wheel must be removed. This is most convenient when the bike is upside down. After the wheel has been removed, unscrew the outer carriage nut. On the opposite side, remove the corkscrew ring to expose the sprocket. Remove the brake mechanism carefully. Be careful not to damage the bearings. Before putting on new brakes, liberally lubricate the drum and brake mechanism. Litol works well as a lubricant.

To begin with, it is worth determining the type of brakes. The most common types are v-brake and disc mechanical.
