ABSTRACT:
Disclosed is a hydraulic brake system for vehicles having a separated-type hydraulic fluid pressure amplifier, such as a hydraulic air servo or a hydraulic vacuum servo. This hydraulic brake system includes a brake master cylinder and said fluid pressure amplifier comprises a hydraulic piston and a control piston, which are moved by the pressure of working fluid from said master cylinder, and a power piston which is moved by the air pressure introduced by the action of the control piston. This hydraulic brake system further includes means for resiliently expanding a fluid passage provided in a part of the hydraulic passage between the brake master cylinder and the portion of the hydraulic fluid pressure amplifier in which the working fluid from the master cylinder is applied to said hydraulic piston and said control piston.
