BRAKE SERVICE PROCEDURES FOR 2002 Buick Century AUTOMOBILES
Power Brake Units -> General Service
Vehicle: 2002 Buick Century Custom 3.1 V6 GAS

The second type is a hydraulic pressure assist mechanism, which use pressure developed by an external pump (usually the power steering pump). Both systems act to increase the force exerted on the master cylinder piston by the operator. This in turn increases the hydraulic pressure delivered to the wheel cylinders while decreasing driver effort required to obtain acceptable stopping performance.
