Abstract

A slip-controlled brake system, especially for use with automotive vehicles has a brake pressure generator (1) accommodating a master cylinder (2) connected to the brake pressure generator through master brake conduits (62,63) are the wheel brakes (31 to 34), comprising hydraulic auxiliary pressure pumps (21,26) and wheel sensors (S1 to S4) and electronic circuits capable to control, for slip control purposed, electromagnetically actuable pressure fluid inlet valves (24,25,29,30) and pressure fluid outlet valves (22,23,35,36) provided in the pressure fluid conduits, with pressure pulsation attenuators (27) of a defined volume expansion and flow length being provided for noise reduction purposed during the control operation, between the master cylinder (2) and the wheel brakes (31 through 34).
