A multiple-circuit hydraulic brake system, in particular for automotive vehicles equipped with a wheel slip control system, in which allocated to the front wheel brakes (7, 8) are anti-skid valves (11, 14, 16, 19) which permit closure of respective hydraulic connections between master cylinder chambers (5, 6) of a braking pressure generator (1) and the front wheel brakes (7, 8) and to remove pressure fluid from said wheel brakes (7, 8), and in which modulator valves (18, 13) are provided in respective brake lines to rear wheel brakes (9, 10) from servo chamber (2) of the generator (1) and which, upon occurrence of an inadmissible pressure decrease due to a fault in a line to a wheel brake (7, 8) of the front axle, bring about a pressure decrease in the respective diagonally opposite rear- axle wheel brake (9, 10). Throttles (12, 17) associated with the anti- skid valves (11, 16) are arranged separately, in particular spaced apart, from the anti-skid valves (11, 16) and a control port (20, 21) of each modulator valve (18, 13) is connected to a line between the respective throttle (12, 17) and anti-skid valve (11, 16). It is thus ensured in a favourable manner that the modulator valves (18, 13) will respond without delay in the event of an inadmissible pressure drop in the front wheel brakes (7, 8). The valves (18, 13) do not operate during wheel slip control as the control lines are pressurised. <IMAGE> |
