Abstract
A hydraulic braking apparatus for braking a vehicle wheel, wherein a pressure control valve is disposed between a master cylinder and a wheel brake cylinder, and between a reservoir and a hydraulic pressure source which is independent of the master cylinder and whose pressure is applied as a braking pressure to the wheel brake cylinder for braking the wheel. The pressure control valve controls the braking pressure as a function of the master cylinder pressure which is generated by the master cylinder, depending upon the operating force acting on a brake operating member. An electrically controlled pressure regulating device is provided for applying an electrically controlled force to the pressure control valve, to thereby regulate the braking pressure to be applied to the wheel brake cylinder.
