ABSTRACT:
This invention relates to an improved self-energizing anti-creep parking and emergency brake mechanism for use with a disc brake assembly. The disc brake assembly includes a first pair of brake shoes disposed on opposite sides of a brake rotor. A service brake mechanism is carried by a caliper and is adapted to be actuated to selectively move the first pair of brake shoes from a non-braking position, wherein the first pair of brake shoes are disengaged from the brake rotor, to a service braking position, wherein the first pair of brake shoes frictionally engage the brake rotor. The disc brake assembly further includes a second pair of brake shoes disposed on opposite sides of the brake rotor. A parking and emergency brake mechanism is carried by the anchor plate and is adapted to be actuated to selectively move the second pair of brake shoes from a non-braking position, wherein the second pair of brake shoes are disengaged from the brake rotor, to a parking and emergency braking position, wherein the second pair of brake shoes frictionally engage the brake rotor. The parking and emergency brake mechanism exerts a predetermined force against the second pair of brake shoes urging them into frictional engagement with the brake rotor when the parking and emergency brake mechanism is applied and there is no relative rotation between the second pair of brake shoes and the brake rotor. The parking and emergency brake mechanism further includes a cam mechanism which exerts an additional force against the second pair of brake shoes urging them into frictional engagement with the brake rotor when the parking and emergency brake is applied and there is relative rotation between the brake rotor and the second pair of brake shoes.
