Types of Bicycle brakes
Bike brakes are divided into two General types. Brakes with hand and foot drive. The first type includes rim brakes and disk.
They are called the rim, because the brake pads are located at the level of the wheel rim. When braking the pads put pressure on the rim, there is a friction and as a result, the Bicycle stops.
Disc brakes – brake mechanism by which the inhibition occurs due to disk, fitted on the wheel and pressing in on his pads. The pressure is generated due to compression. It creates a brake cylinder, which is in most cases on the wheel.
The second type is a drum brake. It is located in the hub of the rear wheel. When you stop the bike, brake the carriage becomes vraspor and presses on the drum. The braking mechanism is designed so that consumable items his are the only bearings.

After it was removed the wheel, loosen the outer nut of the carriage. On the opposite side remove the snap ring to get the star. Remove the brake gently. Be careful not to damage bearings. Before you put new brakes, liberally lubricate the drum and brake mechanism. As lubricants are well suited "Litol".
