Installation Procedure

Important: Lubricate the following components with brake lubricant:
^ The six raised shoe pads on the backing plate
^ The anchor surfaces on the backing plate. The anchor surfaces contact the lower ends of the brake shoes.

1. Reinstall the hooking center spring section under the tab on the anchor, if the return spring was removed.
2. Install the parking brake shoe and lining. Position the shoe and the lining on the backing plate.





3. Use the J 38400 in order to pull up the end of the return spring (2), resting the return spring on the web of the brake shoe (1).
4. Use the J 38400 in order to pull the end of the return spring over until the return spring snaps in the slot in the brake shoe.





5. Connect the parking brake lever (3) to the parking brake shoe and lining (4).
6. Connect the parking brake cable to the parking brake lever, if disconnected.
7. Before reinstallation, disassemble, thoroughly clean and lubricate the adjusting screw (2) in the following manner:
^ Clean the adjuster screw threads with a wire brush.
^ Wash all components in clean denatured alcohol.
^ Apply brake lubricant to the following areas:
- The adjuster screw threads
- The inside the diameter of the adjuster socket
- The socket face
- Adequate lubrication is achieved when a continuous bead of lubricant is on the end of the adjuster nut and the socket when the threads are fully engaged
8. Inspect the threads of the adjuster screw for smooth rotation over the full length.





9. Install the following components:
^ The adjusting screw (2)
^ The adjuster shoe
^ The adjuster shoe lining
^ Engage the adjuster nut end of the adjusting screw (2) with the web of the parking brake shoe and lining and the parking brake lever (3)
^ Position the adjuster shoe and lining so that the shoe web engages the deep slot in the socket end of the adjusting screw
10. Install the return spring into the adjuster shoe and lining.
10.1. Use the J 38400 in order to pull up the end of the return spring, resting the return spring on the web of the brake shoe.
10.2. Use the J 38400 in order to pull the end of the return spring over until the return spring snaps in the slot in the brake shoe.





11. Install the adjuster actuator.
11.1. Lubricate the tab and the pivot point on the adjuster lever with equivalent brake lubricant.
11.2. Use the J 38400 in order to spread the brake shoes while working the adjuster actuator (1) into position.
12. Install the adjuster spring.
12.1. Engage the U-shaped end of the spring in the hole in the web of the parking brake shoe.
12.2. Use the J 38400 in order to stretch the spring and engage the loop end over the tab on the adjuster actuator.





13. Note the following items in order to ensure the proper positioning and function of the adjuster actuator:
^ The adjuster actuator (8) pivots in the shoe web slot
^ The notch in the adjuster actuator rests on the step in the adjusting screw (2) notch
^ The arm of the adjuster actuator rests freely on the star wheel teeth of the adjuster screw, not trapped under the teeth in a downward angle
^ Use the J 38400 between the upper ends of the shoe and lining assemblies. Spread the shoes apart and watch for proper rotation of the star wheel
14. Adjust the brakes. Refer to Drum Brake Adjustment.
15. Adjust the parking brake.
For the drum brakes, refer to Park Brake Cable Service/Adjustment.
16. Install the brake drums. Align the marks made during removal.
17. Install the tires and the wheels. Align the marks made during removal.
18. Lower the vehicle.
