Abstract
In the braking system of a motor vehicle, a hydraulically or electromagnetically actuatable valve is inserted into the return line to control and monitor hydraulic brake slip control devices supplied with energy from an external source. This valve opens or closes the return passage of hydraulic fluid from pressure reducing valves of static brake circuits in dependence upon the dynamic pressure developing in the booster chamber of brake valve network or in the prechamber of the master cylinder upon application of the brake or upon start of the brake slip control. Pressure reduction in the static brake circuits for preventing a wheel lock-up will thereby be avoided, if in the event of a control action no dynamic pressure develops in the booster chamber or in the prechamber on account of a defect.
