Removal & Installation
- Raise vehicle.
- Remove the wheel mounting nuts, then the tire and wheel assembly.
Slide the brake drum (4) off the wheel mounting studs of the hub and bearing (5) and remove it from the vehicle.
NOTEIf the drum does not come off, further brake clearance can be obtained by backing off the brake adjuster screw. To do so, perform the following procedure.
- Remove the plug from the rear of the support plate below the wheel cylinder.
Insert a small screwdriver through the access hole (2) in the support plate, under the adjuster, against the lever pawl. The pawl is attached to and pivots from the rear brake shoe.
- While pushing on the pawl with the screwdriver to disengage it from the adjuster wheel teeth, rotate the wheel (1) upward to back off the adjustment using another screwdriver or a brake adjuster tool.
- Once the adjuster screw is backed off a sufficient amount, slide the drum off the wheel mounting studs.
Before installing drum, inspect brake shoe linings for wear, alignment, and contamination. Repair or replace as necessary.
If rust or any foreign material is present on hub, drum or wheel mating surfaces, wet wire brush these areas to remove prior to assembly of parts.
- Properly remove any buildup formed along outer edge of drum's machined braking surface.
- Adjust the brake shoes-to-drum diameter using a brake shoe gauge.
- Slide the brake drum onto the wheel mounting studs on the hub and bearing.
