Abstract: A vehicle disc brake assembly includes a brake caliper. The brake caliper has a lug through which a bore extends, the bore having an axis. A guide rod fastener extends through the bore and is secured to a guide rod. An elastic bushing is in the bore between the lug and the guide rod fastener, wherein a circumference of the bushing contacts the lug. A radial clearance is between the lug and the guide rod fastener. The radial clearance is perpendicular to the axis.

Abstract: In order to facilitate assembly and disassembly of a vehicle, the invention provides a method of assembling and disassembly a drum brake (1). In this assembly and disassembly method, the operating spacing of two brake shoes (4 and 5) inside a drum brake (3) is pre-adjusted. The invention makes it possible for the drum brake (1) to be delivered with the brake shoes (4 and 5) in a position where they are clamped against each other, corresponding to assembly clearance, while potentially retaining the spacing needed to match the operating clearance of the drum brake. A single action (A, B) on the hand-brake lever (6) enables the shoes to be moved from assembly clearance to operating clearance.
Abstract: A vehicle brake of the caliper type having electrically actuated active adjustment of the running clearance of a brake lining relative to a brake rotor, wherein, for brake operation, angular displacement of a rotatable component (14) of the brake by an external actuator causes axial displacement of a tappet arrangement (22, 24) within the brake whereby to transmit the actuator input load to the brake lining of the brake. The brake includes a switch for supplying a brake de-adjust signal when the brakes are to be opened for example for lining replacement. The switch is mounted on or in the body of the brake caliper and provides a non-contact switch arrangement actuated by a rotary movement provided by the rotatable component (14) of the brake in response to lining wear.
