Cable

Service and repair operations on the Parking Brake Cable start with releasing the park brake lever before moving forward. You must detach 4 screws at locations 1, 3, 4 and 6 and the 2 clips at locations 2 and 5 to lift the console. Service and repair of the Parking Brake Cable requires disconnecting the power neutral switch connector as well as disconnecting the auxiliary power outlet connector when it exists. First disconnect the park brake switch connector then remove the park brake cable lock nut. Raise and support the vehicle after removing both equalizer-based park brake cables. Start by taking out the two rear tire-wheel assemblies and then detach the two brake drums respectively. You should turn the shoe hold down pins and release the shoe hold down springs before taking out the upper return spring along with the strut, adjuster, adjuster lever, adjuster spring, strut spring, and pawl lever. Eliminate the lower return spring and disconnect the park brake cable from the park brake shoe lever as you note that the color ring on the cable serves for identification. Remove the cable from the backing plate by squeezing the stopper ring and then remove three retainers and their bolts and finally remove the cable and grommet from the vehicle. Installation involves inserting the park brake cable and grommet into the vehicle and securing them with the 3 retainers and bolts while torquing them to 10 nm (88.5 inch lbs.) with new cable having the same color ring as the old cable. The brake cable stopper ring and park brake cable must be installed to the backing plate before moving on to installing the park brake cable spring and nipple end to the park brake shoe lever followed by the lower return spring installation. After inserting the shoe hold down pins into the corresponding holes you must put back the pawl lever , strut spring , adjuster spring , adjuster lever and adjuster followed by the upper return spring and strut and the strut. Lower the vehicle and reinstall the two brake drums together with the two rear tire and wheel assemblies before positioning it in its original height. Position the equalizer with its 15-degree angle parallel to the park brake lever cable before mounting the equalizer onto the park brake cable and pinning it into place followed by tightening the lock nut. Connect the park brake switch connector while adjusting the park brake lever to its position. Attach the console over the shift knob and reinstall auxiliary power outlet connectors if your vehicle has such equipment and power neutral switch connectors if your vehicle uses automatic transmission. Secure the console by installing all 4 screws at points (1,3,4,6) and fastening the remaining 2 clips at (2,5).

Reinstall the lower return spring and the previously removed components, including the upper return spring, strut, adjuster, adjuster lever, adjuster spring, strut spring, and pawl lever.
