ABSTRACT:
During normal braking, a brake fluid supply route is used through which brake fluid is supplied from a master reservoir to wheel cylinders to using first to fourth pumps. When an abnormality occurs, a route is used through which a master cylinder pressure, which is generated by depressing a brake pedal, is transmitted through brake conduits to the wheel cylinders for both front wheels. First to fourth linear valves are provided in parallel with the first to fourth pumps, respectively, and during normal braking, the first to fourth linear valves are operated under duty control to adjust the wheel cylinder pressures that are generated in the wheel cylinders to, respectively.
