A brake system for motor vehicles, which can be actuated in a “brake-by-wire” operating mode both by the vehicle driver and independently of the vehicle driver. In the “brake-by-wire” operating mode the system can be operated in at least one fallback operating mode, with a brake master cylinder, actuated by a brake pedal, having a housing and two pistons, which delimit two pressure chambers, are assigned to brake circuits with wheel brakes, a pressure medium reservoir, one electrically actuable inlet valve per wheel brake for setting wheel-individual brake pressures, a first electrically controllable pressure provision device for loading the wheel brakes with pressure, and a second electrically controllable pressure provision device with at least one vacuum connector and a pressure connector, the vacuum connector is connected to the pressure medium reservoir.
