Parking Brake Tensioner: Description and Operation
Park Brake Cable Adjuster
Removes slack in park brake cables.
Park Brake Cable Equalizer
Evenly distributes input force to both the left and right park brake units.
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 reward.
