Abstract: A disc brake assembly having an anchor bracket, a disc type of service brake assembly having a first brake caliper configured to be secured to the anchor bracket; and an electric disc type of parking and emergency brake assembly having a second brake caliper configured to be secured to the anchor bracket.

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 vehicle disc brake assembly comprises a brake caliper and an anchor bracket. The brake caliper has a lug, a bore, an opening, a fastener, and a guide pin. The lug has first and second side faces. The bore extends from the first side face to the second side face. The opening is to the bore at the first side face. The fastener has a transition portion between a bolt stem and a bolt head. The transition portion is fitted to the opening. The guide pin is attached to the fastener. The anchor bracket is supported on the guide pin.

Abstract: A disc brake assembly comprises an anchor bracket having a pair of arms, a caliper supported on the bracket and a non-rotatable vehicle component having a pair of lugs, each of the lugs provided with a non-threaded opening formed therethrough. The non-threaded openings receive fasteners installed in threaded openings of the bracket to secure the vehicle component to the bracket. The bracket includes on at least one of the arms a first shoulder at a transition between the first and second portions thereof. The vehicle component includes on at least one of the lugs a second shoulder having a shape which is generally complimentary to the shape of the first shoulder. When the vehicle component and bracket are secured together, selected surfaces of the first and second shoulders contact each other to substantially prevent movement of the bracket relative to the vehicle component.

Abstract: A slide pin bushing for use in a vehicle disc brake caliper assembly adapted to selectively frictionally engage a rotor connected to a vehicle wheel includes an anchor plate adapted to be secured to a stationary component of the vehicle, and a caliper secured to the anchor plate for sliding movement relative thereto. A pair of brake pads are carried by the disc brake caliper assembly, and an actuation means is provided for selectively moving the brake pads axially toward and away from one another so as to selectively frictionally engage the rotor. An elastomeric slide pin bushing is disposed in a non-threaded opening formed in the caliper. The slide pin bushing includes an outer end section, an intermediate section, and an inner end section. The intermediate section has an inner surface and an outer surface. The inner surface is provided with at least one groove formed therein. The groove is provided with a first end and a second end.
