摘要

A sliding-caliper disc brake assembly includes an H-shaped anti-rattle spring for a brake backing plate that is movable directly by a brake apply piston and an electrical lining wear indicator comprising a mounting portion molded from electrically insulating plastics material with an embedded loop of electrical contact wire fastened on to a central region of the anti-rattle spring. A leg of the mounting portion extends into a recess formed in a layer of friction material carried by the brake backing plate. The mounting block is formed with an internal recess a pair of lateral locating arms and a snap-over detent tongue for co-operation with the anti-rattle spring to ensure secure retention of the mounting portion in position on the spring.
