Vehicle: 1991 Oldsmobile Toronado 3.8 V6 GAS
Two basic types of power assist mechanisms are used: vacuum assist diaphragm assemblies, which use engine vacuum or, in some cases vacuum pressure developed by an external vacuum pump. 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 necessary to obtain acceptable stopping performance.

Vehicle: 1991 Oldsmobile Toronado Trofeo 3.8 V6 GAS
DESCRIPTION
This booster is a single diaphragm, vacuum suspended unit with a lightweight cast alloy housing,Fig. . Vacuum is applied to the front and rear housings. When the brake pedal is released, negative pressure is equalized on both sides of the diaphragm and power piston assembly. Spring tension holds the piston at the rest position. When the brakes are applied, the atmospheric port in the power piston is opened. Negative pressure in the front chamber pulls the diaphragm and vacuum piston assembly, reaction disc and output rod forward. Pressure on the master c...
