The park brake system consists of the following:

Park Brake Pedal Assembly: Receives and transfers park brake system apply input force from driver to park brake cable system.
Park Brake Release Handle Assembly: Releases applied park brake system when pulled.
Park Brake Cables: Transfers input force received from park brake pedal, through park brake cable equalizer, to park brake apply lever.
Park Brake Cable Equalizer: Evenly distributes input force to both the left and right park brake units.
Threaded park brake cable equalizers are also used to remove slack in park brake cables.
Park Brake Apply Lever: Multiplies and transfers input force to park brake actuator.
Park Brake Actuator/Adjuster: Uses multiplied input force from apply lever to expand park brake shoe toward the friction surface of the drum-in-hat portion of the rear brake rotor.
Threaded park brake actuators are also used to control clearance between the park brake shoe and the friction surface of the drum-in-hat portion of the rear brake rotor.
Park Brake Shoe: Applies mechanical output force from park brake actuator to friction surface of the drum-in-hat portion of the rear brake rotor.
