The invention relates to a brake system for motor vehicles, comprising: an actuating device (BP), in particular in the form of a brake pedal; a travel simulator (WS) for producing a reactive force on the actuating device (BP); a first piston-cylinder device (HZE), said piston-cylinder device (HZE) having at least one piston (SK) which separates two working chambers (A1, A2) from one another, each working chamber (A1, A2) being connected to at least one wheel brake (RB1-4) of a brake circuit (BK1, BK2) via at least one hydraulic connection line (VL1, VL2); a control device, each brake circuit (BK1, BK2) being associated with at least one wheel brake (RB1, RB2, RB3, RB4), and each wheel brake (RB1, RB2, RB3, RB4) being connectible to the connection line (VL1, VL2) associated therewith for pressure buildup (pauf) and pressure relief (pab) via the controllable switching valve (SV1, SV2, SV3, SV4) associated therewith; and at least one electric motor-driven pressure supply unit (DE) which has at least one working chamber (4, 4a), and wherein the brake pressure can be built up or relieved by the pressure supply unit (DE) simultaneously or successively optionally in one or more wheel brakes (RB1, RB2, RB3, RB4). The brake system is characterized in that either only one wheel brake (RB1, RB3) is associated with an outlet valve (AV1, AV3) or that only one wheel brake (RB1, RB3) of each brake circuit (BK1, BK2) is associated with an outlet valve (AV1, AV3), the outlet valve (AV1, AV3) being mounted in a hydraulic connection between the wheel brake and the pressure medium storage container (10) and no other valve being mounted between the outlet valve (AV1, AV3) and the pressure medium storage container (10). |
