Park Brake System Operation
WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Park brake apply input force is received by the park brake pedal assembly being depressed, transferred through the park brake cable and the park brake cable clevis to the park brake apply lever. The park brake apply lever multiplies and uses the apply input force to expand the park brake shoes toward the friction surface of the park brake drum in order to prevent the rotation of the propeller shaft system, which will in turn prevent the rotation of the rear drive axle. The park brake release handle assembly releases an applied park brake system when it is pulled reward.
