Cables

Print

This vehicle is equipped with coated parking brake cable assemblies. The wire strand is coated with a clear plastic material which slides over plastic seals inside the conduit end fittings. This is for corrosion protection and reduced parking brake effort.

Handling of these cables during servicing of the parking brake system requires extra care. Damage to the plastic coating will reduce corrosion protection and if the damaged area passes through the seal, increased parking brake effort could result. Contact of the coating with sharp-edged tools, or with sharp surfaces of the vehicle underbody should be avoided. Do not lubricate the parking brake cables. Lubrication may damage the plastic coating on the parking brake cables.

To prevent damage to the threaded parking brake adjusting rod when servicing the parking brake, the following is recommended: before attempting to turn the adjusting nut, clean the exposed threads on each side of the nut; lubricate the threads of the adjusting rod before turning the nut.

If any one of the parking brake cables has been replaced, it is necessary to pre-stretch the new cable before adjusting the parking brake. To do this, apply the parking brake pedal several times. Fully release it each time. The parking brake pedal assembly, located on the dash panel left of the service brake pedal, is a push-to-release type mechanism which is APPLIED by depressing the pedal once and RELEASED by depressing the pedal again. No release handle is used.


WARNING
This is a parking brake NOT a emergency brake. It is designed to hold the vehicle on a flat or an incline and will not stop a vehicle in motion.

  1. Apply the parking brake pedal three times with heavy force of about 175 lbs. (778 N).
  2.  


NOTE
Do not apply the main/service brake pedal during the next step.

  1. Fully apply and release the parking brake three times.
  2.  
  3. Raise the vehicle and safely support the vehicle with safety stands.
  4.  
  5. Matchmark the position of the wheel to the hub and bearing assembly.
  6.  
  7. Make sure the parking brake is fully released. Turn the ignition switch to the ON position. The BRAKE warning lamp should be off. If the BRAKE warning light is still on, pull downward on the front parking brake to remove the slack from the pedal assembly.
  8.  
  9. Remove the rear wheel and tire assemblies, then reinstall two lug nuts to retain the rotors.
  10.  
  11. The parking brake levers on both calipers should be against the lever stops on the caliper housing. If not against the stops, check for binding in the rear cables and/or loosen the cables at the adjuster until both left and right levers are against their stops.
  12.  
  13. Tighten the parking brake cable at the adjuster until either the right or left lever reaches the dimensions shown in the accompanying figure.
  14.  


NOTE
Do not apply the main/service brake pedal during the next step.

  1. Operate the parking brake several times to check adjustments. A firm pedal should be present. The rear wheels should not rotate forward when the parking brake is fully applies. If necessary, repeat steps 8 and 9.
  2.  
  3. Remove the two wheel lug nuts, then install the rear wheel and tire assemblies.
  4.  
  5. Carefully lower the vehicle.
