TSB 98-5A-35 Rear Parking Brake Cables Bind - Vehicles Built Before 8/20/96, except chassis cab
Publication Date: MARCH 18, 1998
LIGHT TRUCK: 1992-97 F-250, F-350
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.
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. Slide the cable in and out to make sure it moves freely on each side. If any sticking and/or binding is evident, replace the parking brake cables. If there is no sticking and/or binding, proceed to Step 7.
7. Reroute the driver side cable in the following manner:
a. It should be routed through the outside left of the butterfly clip, up through the spring hanger between the bracket and frame and to the top hole of the parking brake equalizer bracket.
b. Insert the rear portion of the parking brake cable and conduit through the slot in the parking brake lever at the left rear wheel.
c. Insert the front end of the parking brake cable and conduit through the top hole of the parking brake equalizer bracket until the prongs expand.
8. Reroute the passenger side cable in the following manner:
a. It should be routed through the inside right of the butterfly clip, under the spring hanger bracket and into the bottom hole of the parking brake equalizer bracket ( Figure 1 ).
b. Insert the rear portion of the parking brake cable and conduit through the slot in the parking brake lever at the right rear wheel.
c. Insert the front end of the parking brake cable and conduit through the bottom hole of the parking brake equalizer bracket until the prongs expand.
9. Install a piece of Windlace (E8TZ-1353-A) to the top front edge of the spring hanger bracket where the left rear parking brake cable crosses over it.
NOTE: WINDLACE MUST BE INSTALLED ON THE SPRING HANGER BRACKET, OTHERWISE CHAFING OF THE PARKING BRAKE CABLE COULD OCCUR.
10. Reinstall the rear brake drums, wheels and readjust the rear parking brake as outlined in the appropriate F-Series Service Manual, Section 06-02.
11. Remove the drill bit or equivalent which was inserted in the parking brake control to take up cable slack.
12. Operate the parking brake three (3) times to verify it is operating correctly.
