Subject:
SQUEALING NOISE FROM REAR BRAKE





APPLICABLE MODELS/VINS

DESCRIPTION
A squeal may be heard from the rear wheels when applying the brakes. This noise may be caused by a small amount of grease on the brake drum. This grease is originally applied to the dust seal which is installed to prevent dirt from damaging the wheel bearing. To prevent this condition, the amount of grease applied to the dust seal during production has been decreased.

REPAIR PROCEDURE
1. Verify the complaint.
2. Remove the rear drum and brake shoes according to the instructions in the workshop manual.
3. Remove all dirt and grease from the wheel backing plate and brake drums.
4. Replace the brake shoes according to the instructions in the workshop manual.

NOTE:
Do not remove the remaining grease from the dust seal.

5. Inspect all related parts for wear and machine the brake drum as necessary.

NOTE:
Maximum allowable brake drum inside diameter is stamped on the exterior drum surface. Only drums containing deep grooves or blue (hot) spots should be replaced. Drums not showing these signs should be resurfaced by machining as long as the maximum inside diameter is not exceeded.

6. Assemble automatic adjuster, drum and lock nut according to the workshop manual.
