Disc brake is a hydraulic type of brake that is used for slowing or stopping of vehicles using frictional force between Pads and the Disc. When the brake lever is pressed, it actuates a small piston housed inside the calliper by hydraulic pressure. When force act on Piston, it exerts a static force on the surface of the disc brakes converting the kinetic energy of the discs into heat energy. Accordingly, vehicle is stopped or slowed down.
