Abstract
A vehicle brake system having a power booster coupled to a master cylinder for normally supplying fluid pressure to the wheel cylinders of the vehicle includes an anti-skid device comprising an actuator hydraulically connected in parallel with the power booster for applying brake pressure to the wheel cylinders independently of the power booster when skidding occurs. The brake system includes solenoid controlled valves responsive to electrical signals generated when skidding occurs and operative to interrupt hydraulic communication between the power booster and wheel cylinders while establishing hydraulic communication between the actuator and the wheel cylinders.
