ABSTRACT:
A brake system has a manually controlled brake pressure generator, independent controlled brake circuits each having a wheel brake and a flow control valve for electronically controlling the pressure of the wheel brake, a dynamic pressure source necessary for the pressure control by the flow control valve, a reservoir, a sensor such as a wheel speed sensor, and an electronic control unit. A pair of check valves for introducing and returning fluid are provided in parallel to each other between an output circuit of the brake pressure generator and each controlled brake circuit. A solenoid changeover valve for antilock is provided between the output circuit of the brake pressure generator and the check valves for introducing fluid to close the line during antilock control.
