Hydraulic Brake Booster: Description and Operation

    The booster/master cylinder assembly contains the necessary valves and pistons to develop hydraulic pressure in the wheel circuits during brake
application. Power brake assist is provided through the use of pressurized brake fluid supplied by the hydraulic accumulator.
