ABSTRACT:
A hydraulic brake system for a vehicle includes a cutoff valve for isolating a hydraulic modulator for anti lock brake control and traction control, from a brake master cylinder. This cutoff valve is so arranged that the master cylinder fluid pressure forces the cutoff valve to its open state even if the valve is stuck in its closed state by a failure of the system.
