Disc Brakes

Disc Brakes

This type of braking system consists of a disc or rotor that rotates at the same speed as the wheel to which it is attached, straddled by a caliper. The caliper contains brake pads, operated by small pistons, that squeeze against the surface of the disc to slow it down or stop it. Disc brakes operate more efficiently at high temperatures and wet conditions than drum brakes.
