Abstract
In a brake fluid pressure control apparatus for vehicle which controls braking slip and driving slip of wheels, first and second brake conduits are arranged for connecting a master cylinder with a wheel cylinder, respectively. A fluid pressure control valve is arranged in the first brake conduit for controlling the brake fluid pressure of the wheel. Between a main conduit for connecting the master cylinder with the fluid pressure control valve, and the second brake conduiut, a valve apparatus is arranged for connecting the master cylinder with the fluid pressure control valve and cutting off the master cylinder from the second brake conduit normally and during the braking slip control operation, and for cutting off the master cylinder from the fluid pressure control valve and connecting the master cylinder with the second brake conduit during the driving slip control. A check valve is arranged so as to permit brake fluid to flow from the master cylinder side towards the wheel cylinder side.
