Abstract
An anti-skid brake control system includes a source of fluid pressure, front and rear wheel brakes, a brake booster operatively connected to a vehicle brake pedal and capable of generating power hydraulic pressure in accordance with the depression force of such vehicle brake pedal, and a master cylinder operatively connected to the brake booster for supplying fluid pressure to the front and rear wheel brakes in accordance with the actuation of the brake booster. A first control valve is interposed between one of the front wheel brakes and the brake booster and a second control valve is likewise interposed between one of the rear wheel brakes and the brake booster for decreasing the power pressure of the brake booster to the front and rear wheel brakes in accordance with a skid-condition of the front and rear wheel brakes. A first actuator is also interposed between the other one of the front wheel brakes and the master cylinder and a second actuator is likewise interposed between the other one of the rear wheel brakes and the master cylinder for supplying fluid pressure to the front and rear wheel brakes in accordance with the actuation of the master cylinder, fluid pressure thereby being supplied from the master cylinder to the front and rear wheel brakes under normal braking operations and not being supplied thereto under anti-skid conditions.
