ABSTRACT:
The present invention is directed to a hydraulic brake apparatus for applying braking force to each wheel of a vehicle in response to depression of a brake pedal. An auxiliary pressure source is provided for pressurizing the brake fluid in the reservoir to discharge power pressure. A control piston is slidably disposed in a cylinder body ahead of a master piston to be movable in response to movement thereof, so that a regulator chamber is defined ahead of the control piston, and a rear end thereof is exposed to a pressure chamber. A first pressure receiving device is operatively connected with the control piston for applying thereto first counter brake pressure having a first pressure characteristic, with the power pressure received from the auxiliary pressure source, against the hydraulic brake pressure generated in the pressure chamber and applied to the control piston. A second pressure receiving device is operatively connected with the control piston for applying thereto second counter brake pressure having a second pressure characteristic, as well. And, a restriction device such as a cut-off valve is provided to prevent either one of the first counter brake pressure and second counter brake pressure from being applied to either one of the first pressure receiving device and second pressure receiving device in response to operation of the brake pedal.
