ABSTRACT:
A brake system having at least one static pressure line having a static pressure generator. The static pressure line has a bilateral driving piston having one end thereof acted on by a brake pressure and the other end acted on by a control pressure, a changeover valve capable of shutting off the fluid flow from the static pressure generator to the wheel brake, a flow control valve for controlling the control pressure of the driving piston, and an electronic control unit for giving a control command to the flow control valve. The driving piston is controlled so as to keep its predetermined neutral position while the manual input is zero, and, in a normal operation phase, so as to move in such a direction as to reduce the capacity of the static pressure line so that a manual control stroke will be shortened in a predetermined relationship with deceleration or with other braking factors closely associated with the deceleration. In an antilock control phase, the driving piston is controlled so as to move in such a direction as to increase the capacity of the static pressure line, after the fluid flow from the static pressure generator to the wheel brake has been shut off by said changeover valve.
