Abstract

PURPOSE: To restrain the violent motion of a brake pedal and prevent the uncomfortableness to a driver by supplying a liquid to a master cylinder room by an outside energy source and also supplying fit to a storage tank. CONSTITUTION: A piston pump 41 which is an outside energy source supplies a liquid to master cylinder rooms 13, 14 through buffing rooms 39, 39' and is connected to a storage tank 23 through check valves 45, 45'. At the operation time of a brake control, wheel brake cylinders 32, 34, 35 are intercepted from the master cylinder rooms 13, 14 by magnet valves 28-30 and in the case of discontinuing a pressure increase and avoiding the lock of a brake, the piston pump 41 is operated and the liquid is sent out from the storage tank 23 into the master cylinder rooms 13, 14 and the piston 6 and brake pedal 1 are pushed back. Thus, the violent motion of the brake pedal can be restrained and the uncomfortableness to a driver can be reduced.
