    Q:
    How does the brake application process work for the 1991 Oldsmobile Cutlass, including the role of the Brake Booster? Posted by Shawntele G.
    A:
    Upon brake application, depressing the pedal moves the push rod, which shifts the air valve and allows atmospheric air to enter. This causes the power piston to move forward and operate the hydraulic master cylinder. The hydraulic reaction plate then provides feedback to the pedal, allowing the driver to sense the degree of brake application.
