Abstract
An improved structure for a disc brake piston heat shield adapted for use in a disc brake assembly includes a caliper provided with at least one cylindrical recess formed therein. A piston is slidably disposed in the recess. The piston includes a closed end and an open end. The open end of the piston is provided with at least a pair of projections extending therefrom. The projections define a pair of abutment surfaces and a pair of end surfaces located axially inward relative to the abutment surfaces, A pair of brake shoes are carried by the disc brake assembly and are disposed on opposite axial sides of an associated rotor. Each brake shoe includes a backing plate and a friction pad. An actuation system is carried by the caliper for selectively moving the brake shoes between a non-braking position, wherein each of the friction pads is spaced apart from the adjacent side of the rotor, and a braking position, wherein each of the friction pads frictionally engages the adjacent side of the rotor. A heat shield is attached to the open end of the piston. The heat shield includes a pair of openings generally corresponding to the shape of the projections, a pair of outwardly extending tangs adjacent the openings and adapted to frictionally engage an inner surface of the projections to attach the heat shield to the piston, and a reversely bent back outer peripheral end which is spaced apart from an associated dust boot seal.
