A circuit configuration for an anti-locking brake system controlled according to a multiplex process. The circuit configuration is designed such that upon commencement of an anti-locking control, if the first wheel to become instable is a front wheel (VL) the reswitching of the wheel valves (4) leading to the rear wheel brakes (22, 23), is delayed by a predetermined period of time of about 4 to 20 milliseconds. This therefore prevents the pressure from excessively rising upon commencement of the anti-locking control.

As an improvement on conventional brake systems of the type having a multiple-chamber vacuum brake force booster, a modification is disclosed to the effect that, in the brake releasing position, there is a pressure medium communication between a booster chamber and a simulator chamber. A modulator chamber requires only one external connection, thereby substantially simplifying the construction of the brake force booster and readily permitting an extension of the system's use to include traction slip control.
