Abstract
A fluid pressure brake control apparatus for controlling braking-slip and driving-slip of wheels includes fluid pressure control valves, a fluid pressure pump and a valve apparatus arranged between the fluid pressure control valves and the master cylinder, and between the fluid pressure control valves and a fluid pressure source. In a first condition the fluid pressure valving is connected with the master cylinder while being cut off from the fluid pressure source. In a second condition the fluid pressure control valving is connected with the fluid pressure source while being cut off from the master cylinder. In a third condition the fluid pressure control valving is cut off from both the master cylinder and the fluid pressure source. The apparatus assumes the second condition during driving-slip control and supplies to the fluid pressure source the pressurized brake fluid discharged from the fluid pressure pump.
