Abstract: A disc brake prevents the generation of brake noise by chamfering a pair of friction pads which are disposed at both sides, respectively, of a rotating disc. Each pad includes a backing plate and a lining that is rigidly secured to the backing plate, the lining having a friction surface that is to be pressed against the disc. Both side portions of the lining extend outwardly beyond the outer side surfaces of the corresponding claw portions of a caliper in the widthwise direction. The lining is chamfered at each side portion from a position whose distance from the outer side surface of the corresponding claw portion is in the range of from one third to one fourth of the width of the claw portion.

Abstract: A disc brake includes a rotating disc, a friction pad having a backing plate and a lining fixedly attached to one surface of the backing plate, and a wear sensor for sensing a limit of wear of the lining. The wear sensor is a bent elongate metal plate mounted on the backing plate with one end thereof projecting beyond the front surface of the backing plate. The disc brake is further provided with structure for preventing excessive deflection of the sensor.
