Abstract: The invention relates to a brake system which comprises an actuating device (26), especially a brake pedal (30), and a control/regulation device (22). Said control/regulation device (22) controls an electromotive drive device (8) in response to the movement and/or position (38) of the actuating device (30). The drive device (8) adjusts a piston (1) of a piston/cylinder system via a non-hydraulic transmission device (6), thereby adjusting a pressure in the working compartment (4?) of the cylinder (4). Said working compartment (4?) is connected to a wheel brake (15, 17) via a pressure conduit (13). In case of drive device (8) failure, the actuating device (26) adjusts the piston (1) or the drive device (8).

Abstract: The invention relates to a brake system which comprises an actuating device (26), especially a brake pedal (30), and a control/regulation device (22). Said control/regulation device (22) controls at least one electromotive drive device (7a, 7b, 8) in response to the movement and/or position of the actuating device (26). The drive device adjusts a piston (1, 1a, 1b) of a piston/cylinder system via a non-hydraulic transmission device, thereby adjusting a pressure in the working compartment (4?, 4?a, 4b?) of the cylinder. Said working compartment is connected to a wheel brake (15, 17) via a pressure conduit (13, 13a). A valve (14, 14a, 15, 15a, 14?, 14a?) is interposed between the brake cylinder of the wheel brake and the working compartment of the piston/cylinder system. The control/regulation device opens the valve for pressure suppression or pressure build-up in the brake cylinder and closes it in order to maintain the pressure in the brake cylinder.
