Abstract
A disc brake has a disc rotor, a pair of confronting friction pad assemblies arranged on both sides of the disc rotor, a pad assembly support member fixed to an automotive vehicle body, and a caliper driving piston for moving one of the friction pad assemblies relative to the other in an axial direction of the disc rotor. The pad assemblies are each provided with a pair of lower two engaging steps for transmitting the brake torques to the support member, and also with upper corner shoulders for transmitting the brake torques. The support member is provided with step portions corresponding to the engaging steps and the upper corner shoulders of the brake assemblies. Thus, it is possible to reduce or suppress a deformation of the brake assemblies when the disc rotor rotates upon the brake application.
