ABSTRACT:
A vehicular anti-skid brake device comprising a hydraulically-operated braking device, an anti-skid hydraulic system for automatically controlling the braking force of the braking device relative to the wheels, and a valve responsive to brake oil pressure for annulling malfunction of the anti-skid hydraulic system when braking is not applied. The braking device comprises a brake oil chamber for generating a braking force and a control oil chamber for generating an anti-braking force against the braking force when the latter is excessive. The control oil chamber receives control oil pressure generated by a control oil pressure generating source and is under control of the anti-skid hydraulic system when braking is applied. The valve responsive to brake oil pressure is disposed in an oil passage which provides communication between the control oil pressure generating source and the control oil chamber, the valve being responsive to brake oil pressure generated by a brake oil pressure generating source to normally cut off control oil delivered from the control oil pressure generating source but permitting control oil to be delivered from the control oil pressure generating source when the brake oil pressure exceeds a predetermined pressure.
