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 the…
