ISSUE:
The rear parking brake cables may bind and not allow the rear brake shoes to return fully to the anchor pins after the parking brake is applied. This may
result in early brake wear, rear brake vibration/shudder, rear brake noise, drift/pull condition and/or poor fuel economy. This may be caused by a tight
bend in the parking brake cable at the left side rear spring bracket.
ACTION:
Reroute the parking brake cable and install a windlace on the left rear spring bracket to prevent chafing. This should reduce the possibility of the parking
brake cable binding. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1.
Relieve the tension on the system by having an assistant pull directly rearward on the intermediate or front parking brake cable and conduit. Using
care not to damage the coating on the parking brake cable strand, insert a 4mm drill bit or equivalent into the hole provided in the parking brake
control.
2.
Raise the vehicle and remove the rear wheels and brake drums.
3.
Disconnect the rear brake cables and conduit from the parking brake cable equalizer.
4.
Compress the prongs which retain the parking brake cables and conduit shield to the parking brake cable bracket using a 1/2" 12-point box end
wrench.
5.
With the spring tension released, lift the parking brake cable and conduit out of the slot in the parking brake lever on both sides.
6.

there is no sticking and/or binding, proceed to Step 7.
