Abstract: A composite brake adapter for a caliper disc brake assembly is made up of a first pre-stamped part of a sheet of metal adapted to match an axle housing of the assembly, and of a second part cast onto an upper surface of the first part to adhere thereto, additional structural elements providing matching of the second part with a caliper of the assembly being made an integral part of the second part. A method of making a composite brake adapter for a caliper disc brake assembly comprises the steps of providing a first part of the adapter, the first part being provided with mounting holes to match an axle housing of the assembly and being made of a sheet of metal; placing the first part into a mold, and casting a second part of the adapter into the mold onto a surface of the first part. To incorporate additional structural elements of the adapter with a caliper of the assembly, the additional structural elements are placed into a precision fixture and secured within the mold prior to casting the second part.

Abstract: A vacuum booster assembly having first and second walls defining a vacuum chamber and a diaphragm disposed within said vacuum chamber. The diaphragm includes a beaded peripheral portion which is sealingly engaged between the walls and the beaded portion is adhesively secured to at least one of the walls to prevent movement during assembly.

Abstract: A disc brake for the wheel of a motor vehicle includes a rotor mounted to the wheel, and a caliper straddling the rotor and supporting a brake pad on either side thereof. In order to accommodate packaging constraints within the wheel's rim, the outboard pad and the rotor's outboard friction surface are both positioned radially inwardly of the inboard pad and inboard rotor friction surface. A hydraulic piston located in the inboard portion of the caliper first urges the inboard pad along the piston's longitudinal axis into initial engagement with the rotor's inboard friction surface, whereupon the piston acts through the caliper's bridge and finger area to urge the outboard pad into engagement with the rotor's outboard friction surface. The effective radius of each pad is less than the radial offset of the piston's longitudinal axis from the rotational axis of the wheel and rotor so as to reduce the bending moment applied to the rotor upon braking.

Abstract: A brake slip control system for trailers equipped with overrun brakes is disclosed, in order to make the brake device independent of the towing vehicle, the pressure fluid source is arranged at the trailer.
