Abstract
An anti-squeal disc brake, having a disc rotor rotating with a wheel of a vehicle, a pair of friction pads each including a friction member and a backing plate secured to the friction member, an actuator device for forcing the pair of friction pads against opposite friction surfaces of the disc rotor, and a torque member which is secured to a fixed member of the vehicle and which supports the friction pads movably toward and away from the opposite friction surfaces of the rotor, the torque member receiving, through the backing plates, tangential forces which act on the friction pads during frictional contacts of the friction members with the friction surfaces of the rotor. The backing plate of each of at least one of the friction pads is formed with a force-transmitting portion which transmits to the torque member the tangential force acting on the corresponding friction pad, at a position lying in a plane which includes the corresponding one of the opposite friction surfaces of the rotor, or at a position spaced apart from the above-indicated plane in a direction toward the other friction surface of the rotor.
