Abstract: A brake caliper adapted for use in a vehicle disc brake assembly and method and apparatus for producing the same. The apparatus for producing the brake caliper comprises a mold member and a core member. The mold member has two mold sections meeting at a vertical interface, the first mold section having an extension from the vertical interface into the second mold section to form an integrally cast lug on the brake caliper. The core member has three extensions operative to form three integrally cast locating surfaces on the cast brake caliper, the extensions defining datum surfaces for subsequent machining of the cast brake caliper to predetermined tolerances using the three locating surfaces as the datum surfaces.

Abstract: A drum-in-hat (DIH) disc brake assembly has a backing plate configured to be supported relative to an axle flange and to support a drum brake shoe assembly of the drum-in-hat parking and emergency brake; a caliper bracket configured to be supported relative to the axle flange and to support a disc brake caliper assembly of the disc service brake; and a parking brake anchor configured to be supported relative to the axle flange. The parking brake anchor includes an anchor body and an abutment. The anchor body has an opening formed therein which is configured to receive a lever arm of a parking and emergency brake actuator which extends through the opening in the anchor body.

Abstract: A vehicle drum-in-hat disc brake assembly comprises a drum-in-hat adapter adapted to be secured to a fixed component of a vehicle; a backing plate adapted to be secured to the drum-in-hat adapter and to support a pair of brake shoes therein; a parking and emergency brake actuation mechanism adapted to move the brake shoes apart from another between a braking position and non-braking position, the parking and emergency brake actuation mechanism including a brake actuation lever adapted to be pivotally supported on one of the pair of brake shoes; wherein the backing plate includes at least one raised pad and the brake actuation lever includes an abutment surface provided thereon which is disposed adjacent and in sliding support with the raised pad whereby at least a portion of the abutment surface of the brake actuation lever rests against and is supported by at least a portion of the raised pad when the brake actuation lever of the parking and emergency brake actuation mechanism is in both the braking and non-

Abstract: A drum-in-hat (DIH) disc brake assembly has a disc service brake, a DIH parking and emergency brake, and a parking brake anchor. A backing plate, an axle flange, and a caliper bracket each have at least two mounting apertures formed therethrough. The parking brake anchor includes a bracket portion having a pair of studs extending axially outwardly therefrom. The studs are structured and configured to extend through the respective mounting apertures of the backing plate, the axle flange, and the caliper bracket for securing the caliper bracket, parking brake anchor, and the backing plate to the axle flange.

Abstract: A drum-in-hat disc brake assembly has a disc service brake and a drum-in-hat parking and emergency brake, and includes a backing plate, a pair of parking and emergency brake shoes secured to the backing plate, and a parking and emergency brake actuator. The parking and emergency brake actuator includes a first body portion and a second body portion pivotally mounted to the first body portion. A boss extends between the first body portion and the second body portion. The boss is selectively movable between a plurality of positions and defines a first distance between the first body portion and the second body portion. A lever arm is pivotally mounted to the second body portion and is connected to a parking and emergency brake cable.

Abstract: This invention relates to an adapter for a vehicle brake assembly. The vehicle brake assembly is a vehicle drum-in-hat disc brake assembly having a disc service brake and a drum-in-hat parking and emergency brake. The vehicle drum-in-hat disc brake assembly includes a backing plate having a centrally located first aperture formed therein; a drum brake shoe assembly of the drum-in-hat parking and emergency brake supported by the backing plate; and a drum-in-hat adapter having a centrally located second aperture and a plurality of smaller mounting apertures formed therein about the centrally located first aperture thereof, wherein the adapter is formed as a one piece stamping and including an integral abutment member formed therewith during the stamping thereof.

Abstract: This invention relates to a drum-in-hat disc brake assembly. According to one embodiment of the invention, only four fasteners extend through the associated apertures of the backing plate, the drum-in-hat adapter, the axle flange and the caliper bracket for securing the caliper bracket, drum-in-hat adapter and the backing plate to the axle flange. Two of the four fasteners extend through the two apertures of the caliper bracket and at least partially into two of the four apertures of the axle flange to thereby secure the caliper bracket to the axle flange. The other two of the four fasteners extend through the two smaller apertures of the backing plate and the drum-in-hat adapter and at least partially into the remaining two apertures of the axle flange to thereby secure the backing plate and the drum-in-hat adapter to the axle flange.

Abstract: This invention relates to a brake shoe mounting system for a vehicle brake assembly. The vehicle brake assembly brake shoe mounting system includes a brake mounting member and a pair of brake shoes slidably supported relative to the brake mounting member. The brake member is adapted to be secured to a fixed, non-rotatable component of the vehicle and includes an abutment having a pair of opposed slots formed therein. Each brake shoe includes a first end, an opposite second end, a web portion, a rim portion secured to an outer surface of the web portion, a friction pad secured to an outer surface of the rim portion, and only two shoe slides provided on at least one side of the rim portion. One of the two shoe slides is provided near the first end of the brake shoe and the other of the two shoe slides is provided generally intermediate the first and second ends of the brake shoe. In accordance with this invention, the second end of the brake shoe defines a shoe abutment end.
