The disc brake is open system of braking in which disc rotation decreases by the clamping the brake pads. The main elements of disc brake is pair: pads and disc.
The advantages of this system be obvious, because it cools faster and it`s easier to clean. However, it has some disadvantages like quick wearing of pads.
When in disc braking, the brake pads press the disc, in drum versions they expand slightly to slow down the drum and, accordingly, the wheel.
