Abstract
A hydraulic servo brake system with slip control. Brake circuits (18, 22, 25) with supply valves (28, 32, 35) and discharge valves (29, 33, 36) for the control of the wheel cylinder pressures during slip control are provided. Throttle points (38) are arranged within the supply valves. Each supply valve is bridged by an auxiliary valve (31, 34, 37) which is switchable into the closed position when the slip control action sets in. In this manner, the pressure gradient for the brake pressure build-up in the wheel cylinders is high before the slip control and low during the slip control.
