System Component Description

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The park brake system consists of the following:

Park Brake Lever Assembly: Receives, multiplies, and transfers park brake system apply input force from operator to park brake cable system.
Releases applied park brake system when lever is returned to at-rest, lowered, position.
Park Brake Cables: Transfers input force received from park brake lever, through park brake cable equalizer, to park brake apply levers.
Park Brake Cable Equalizer: Evenly distributes input force to both the left and right park brake units.
Park Brake Apply Lever: Multiplies and transfers input force to park brake actuator/adjuster.
Park Brake Actuator/Adjuster: Uses multiplied input force from apply lever to expand drum brake shoes toward the friction surface of the brake drum.
Threaded park brake actuators/adjusters are also used to control clearance between the drum brake shoes and the friction surface of the brake drum.
Drum Brake Shoes: Applies mechanical output force from park brake actuator/adjuster to friction surface of the brake drum.
