A brake system with slip control for vehicles with front-wheel drive or all-wheel drive comprises two hydraulically isolated pressure-medium circuits (2, 3), to which one front wheel and one rear wheel each (VL, HR; VR, HL) are connected. Through a pair of valves (17, 19; 18, 20) consisting of inlet valve and outlet valve, the braking pressure in the two hydraulic pressure-medium circuits is varied upon recognition of an imminent locked condition. The braking pressure in the front-wheel brake is maintained constant by one additional valve (21, 22) connected upstream of the front-wheel brakes (4, 6) in the event of decrease or in the event of further increase of the pressure in the rear-wheel brake (5, 7) that is connected to the same hydraulic pressure-medium circuit (2 or 3, respectively). |
