ABSTRACT:
In a hydraulic brake system of the present invention, the communication between a power chamber 30 of a hydraulic booster 2 and wheel cylinders (WCY) 58, 59 is allowed by a switching valve 64 when fluid pressure of an accumulator (ACC) 46 exceeds predetermined pressure. During braking operation, the fluid pressure of the ACC 46 introduced in the power chamber 30 is introduced directly to the WCYs 58, 59, thereby rapidly actuating brakes and thus improving the response. When the fluid pressure of the ACC 46 is less than the predetermined pressure, the communication between a fluid chamber 57 of a master cylinder (MCY) 3 and the WCYs 58, 59 is allowed by the switching valve 64. During braking operation, MCY pressure developed by a MCY piston 53 operated by an input shaft 21 through a power piston 10 is introduced into the WCYs 58, 59 through the switching valve 64. The brakes can securely work even when the fluid pressure of the ACC 46 is less than the predetermined pressure.
