Abstract: A disc brake for a motor vehicle, wherein the disc brake comprises a housing, a brake disc which can be rotated relative to the housing, at least one friction lining, and at least one actuating device which is configured for bringing about a relative movement between the brake disc and the friction lining, with the result that the friction lining can be brought into contact with the brake disc, wherein the actuating device has at least one actuating piston which is guided displaceably in the housing in a hydraulically sealing manner, wherein the actuating piston can be displaced in the housing hydraulically and via a mechanical actuator. In the disc brake, it is provided that the actuating piston is coupled to the mechanical actuator via an elastically deformable driving arrangement, wherein, as a consequence of a relative displacement between the actuating piston and the actuator, the driving arrangement provides a restoring movement in accordance with its elastic deformation.

Abstract: A vehicle brake system including a wheel brake and a master cylinder operable to provide pressurized fluid to the wheel brake. The master cylinder includes a housing having a bore formed therein, and further including a piston slidably disposed in the bore. The brake system further includes a fluid reservoir in selective fluid communication with the bore of the master cylinder. The brake system also includes an isolation valve movable between an open position, wherein fluid is permitted to flow between the master cylinder and the wheel brake, and a closed position, wherein fluid is restricted from flowing between the master cylinder and the wheel brake. The brake system further includes a dump valve movable between a closed position, wherein fluid is prevented from flowing between the wheel brake and the reservoir, and an open position, wherein fluid is permitted to flow between the wheel brake and the reservoir.
