Abstract
A brake hydraulic pressure circuit for increasing the speed of pressure increase at the wheel cylinder by the simple hydraulic circuit. An accumulator is connected to the discharging side of the pump of the hydraulic return circuit via a first switching valve. A hydraulic supplying circuit, branching from the line between the first switching valve and the accumulator, is connected to the suction side of the pump of the hydraulic returning circuit via a second switching valve. Brake fluid reserved in the accumulator is then supplied to the main hydraulic circuit and is supplied to the suction side of the pump via the hydraulic supply circuit.
