Hydraulic brake system with slip control

A hydraulic brake system with slip control for automotive vehicles, comprising a master cylinder (2) pressurizable by means of a hydraulic power booster (1), wherein valve means (23, 38) are provided between the master cylinder (2) and wheel brakes (24, 25, 29, 30) connected to the master cylinder, through the intermediary of said valve means a pressure medium is drawn from the wheel brakes (24, 25, 29, 30), the pressure medium drawn from the wheel brakes being replenishable from a pressure chamber (10) of the hydraulic power booster (1), and wherein a limitation of the lift of a brake pedal (8) occurs during the slip control, wherein a booster sleeve (52) is provided which annularly encloses a booster piston (4) of said booster (1) and whose end face directed towards the pressure chamber (10) of the booster (1) is acted upon by the pressure in the pressure chamber (10), the booster sleeve (52) being coupled to the booster piston (4) by way of a stop in the form of a circlip (53), and whereupon movement of the booster piston (4) in the direction of brake release, the booster sleeve (52) is entrained by the booster piston (4), and on displacement of the booster piston (4) exclusively by way of a push rod (9) articulated at the brake pedal (8) in the direction of a brake actuation, the booster sleeve (52) will remain in its initial position.
