A brake fluid pressure control apparatus comprises a fluid pressure control valve provided in a supply passage communicating a master cylinder with wheel cylinders, a stepped piston slidably fitted into the fluid pressure control valve and urged by a return spring in one direction toward a stop piston, a fluid pressure chamber provided in the central portion of the fluid pressure control valve in such a manner as to communicate with the supply passage, and a back pressure chamber provided in the other side of the stepped postion. The pressure fluid returned to the back pressure chamber at the time of a decrease of the pressure during anti-lock control is received by the stepped piston and is returned through a throttle portion to the master cylinder side, thereby relieving any kickback acting upon the brake pedal.
