ABSTRACT:
In an anti-skid control apparatus which includes two independent conduit systems having diagonally connected brake conduits for a pair of front wheels and a pair of rear wheels, fluid pressure control valve devices are arranged in the respective brake conduits and a valve apparatus for generating a fluid pressure in accordance with the lower one of the brake fluid pressures of the front wheels is controlled by the fluid pressure control valve device. The valve apparatus is disposed between the wheel cylinders of the front wheels and those of the rear wheels. The one fluid pressure control valve device for the one front wheel running on the low side is normally controlled by conbining logically the signals indicating the skid conditions of the rear wheels with the signals indicating the skid conditions of the one front wheel on the low side. If the valve apparatus fails, it is made to be controlled by combining logically the signals indicating the skid condition of the one rear wheel on the high side with those of the one front wheel on the low side.
