ABSTRACT:
A disc brake comprises a disc rotor, a pair of braking pad assemblies consisting of a friction pad and a backing plate, a transmitting member for transmitting urging force from an actuator to the braking pad assembly, a stopper for limiting the movement amount of the braking pad assembly in the rotational direction of the disc rotor, and a pad return spring. The total thickness of the backing plate plus the transmitting member is made variable through a slant surface made on both members respectively in a complementary contacting state. When the brake is applied the backing plate is slidably moved the rotational direction of the disc rotor along the slant surface of the transmitting member to increase the total thickness before it abuts a stopper member, and when the brake is released the total thickness is decreased to the original value by the movement of the backing plate in the reverse direction by the pad return spring along the slant surface to ensure the brake clearance between the braking pad assembly and the disc rotor.
