ABSTRACT:
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.
