A motor vehicle braking system and method operable in a brake-by-wire mode and independently of the driver, with a master brake cylinder (2) operated by a brake pedal (1) having a piston (15, 16) and a pressure chamber (17, 18), connected with a brake circuit (I, II) and wheel brakes (8,9, 10, 11). An electrically controllable pressure supplying device (5) operates the wheel brakes; and a simulation device (3) with at least one elastic element (33), provides an acceptable brake pedal feel in the brake-by-wire mode. The simulation device (3) has a simulator chamber (29) connected, or is hydraulically connected, through a first hydraulic connection (54) to the pressure chamber (17) and which has an electrically actuated isolation valve (28) with a pressure means reservoir (4) under atmospheric pressure. A media separator device (47) is arranged in the connection (46) between the simulator chamber (29) and the isolation valve (28). |
