How to Replace Drum Shoes on a 1993 Nissan Pathfinder

Of all the features on the 1993 Nissan Pathfinder, the brakes are probably the most important. The materials used to make the pads and shoes for the disc and drum brakes are very durable, so changing the brakes frequently is unnecessary. However, even the best materials wear out over time, and eventually youll have to replace your Pathfinders rear drum brake shoes. It isnt a complicated job, but working on drum brakes can be tedious. Allow at least two hours to complete the task.

Instructions

1

Loosen the lug nuts on the rear wheels, and raise the rear of the vehicle with an auto jack. Support both sides with a jack stand. Remove the lug nuts and both rear wheels.

2

Pull the brake drum from the lugs. Inspect the inside of the drum to ensure there are no grooves cut into the line. If grooves are present, first either replace the drum or take it to a machine shop for repair.

3

Place a drip pan under the brake components. Flush the parts with brake cleaner to remove dangerous dust particles. Allow the parts to air dry.

4

Place a brake tool over the shoe hold-down anti-rattle spring retainer and rotate it clockwise to unlock the spring. Remove the retainers, springs, spring seats and pins. Repeat for the spring on the other brake shoe.

5

Remove the upper and lower brake return springs using needle-nose pliers. These are the long springs that run parallel to the ground.

6

Remove the brake shoes from the backing plate. The parking brake cable is still attached to the secondary shoe. Use pliers to remove the clevis pin and disconnect it from the shoe.

7

Remove the rubber boot located behind the backing plate, which allows you to remove the adjuster shim, lockplate and adjuster springs.

8

Discard the brake shoes and clean all other components with brake cleaner.

9

Apply high-temperature grease to the adjuster, adjuster wheel, backing plate springs and any place that moving parts contact the backing plate.

10

Rotate the adjuster screw so it is at the shortest possible setting. Reconnect the secondary brake shoe to the parking brake toggle lever and replace the clevis pin.

11

Replace the adjuster shim, lockplate and adjuster springs. If you cant remember exactly how they fit, refer to the opposite brake assembly.

12

Place the shoes onto the backing plate. Reconnect the upper and lower brake return springs, ensuring the springs are securely seated in the holes.

13

Use the brake tool to reassemble the anti-rattle retainers, springs, spring seats and pins. Fit the parts together, place them into position and press the spring down while rotating it 90 degrees to lock it into place.

14

Use a flat screwdriver to rotate the wheel on the adjuster until the diameter of the brake shoes is 0.0098-0.0157 less than the inside diameter of the drum. Compare the brake assembly to the one you have not yet disassembled to ensure the components are properly installed. Repeat the procedure on the remaining assembly.

15

Replace the wheels and lug nuts, and spin the wheels to ensure they turn freely. If not, use the adjuster to decrease the diameter of the brake shoes. Lower the vehicle and tighten the lug nuts. Operate the parking brake several times to adjust it correctly.

16

Locate a safe driving area where you can perform several rapid braking maneuvers. Drive the vehicle in reverse a few feet and then quickly stop it. Drive forward and do the same. Repeat back-and-forth braking several times to seat the shoes and ensure the self-adjuster is working correctly.
