Abstract: Master cylinder assembly (1) for hydraulic control includes a master cylinder body (2) having a longitudinal bore (3). A piston (6) is arranged in the said bore and includes a seal packing (15) separating two chambers (16, 29) adapted to contain a liquid. The piston also includes a recovery conduit (36) connecting the chambers and by-passes the seal packing, and a valve (38). When the piston is in a rest position, an actuator (54) adjusts the position of the valve between an open position opening the recovery conduit and a closed position closing the recovery conduit.

Abstract: The invention provides a multi-disc brake for a vehicle having a knuckle for supporting a wheel of a vehicle and a hub mounted for rotation on the knuckle about a rotation axis. The multi-disc brake also includes a pair of discs mounted for rotation with and sliding movement on the hub along the rotation axis. Each disc includes inboard and outboard engaging surfaces. The multi-disc brake also includes a plurality of brake pad assemblies disposed in alternating arrangement between the discs. The multi-disc brake also includes a caliper (62) disposed for sliding movement relative to the knuckle and having an inboard wall (64) and a bridge portion (66) extending from the inboard wall (64) around the discs and the brake pad assemblies to an outboard wall (68) adjacent to the outboard brake pad assembly.
