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.
