System Component Description
The park brake system consists of the following
System Operation
Park brake apply input force is received by the park brake pedal assembly being depressed, transferred and evenly distributed, through the park brake cables and the park brake cable equalizer, to the left and right park brake apply levers. The park brake apply levers multiply and transfer the apply input force to the park brake actuators which expand the park brake shoe toward the friction surface of the drum-in-hat portion of the rear brake rotor in order to prevent the rotation of the rear tire and wheel assemblies. The park brake release handle assembly releases an applied park brake system when it is pulled rearward.
The park brake system consists of the following
Depressing the park brake pedal creates input force. The input force is transferred and evenly distributed through the front park brake cable and the equalizer to the left and right rear park brake cables. The input force, is then transferred to the apply levers located in each of the rear brake drums. The levers then multiply the input force and transfer the force to the rear brake shoes. At that point, the brake shoes are forced to expand and make contact with the friction surface of the rear brake drums, preventing the rotation of the rear wheels. Use the park brake release handle to disengage the park brake.
