When servicing drum brakes, only dissemble and assemble one side at a time, leaving the remaining side intact for reference.
REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 5
- Loosen the rear wheel lug nuts slightly. Release the parking brake.
- Block the front wheels, raise the rear of the car, and safely support it with jackstands.
- Remove the lug nuts and the wheel.
One way to remove the drum is to tap the drum lightly with a mallet to free the drum if resistance is felt. Sometimes brake drums are stubborn. If the drum is difficult to remove, perform the following:
- Insert the end of a bent wire (a coat hanger will do nicely) through the hole in the brake drum and hold the automatic adjusting lever away from the adjuster.
Reduce the brake shoe adjustment by turning the adjuster bolt with a brake adjuster tool. The drum should now be loose enough to remove without much effort.
- Another way to remove the brake drum is to insert a bolt in each of the two holes in the drum.
- Clean the drum and inspect it as detailed in this Section.
- Hold the brake drum so that the hole on the drum is aligned with the large hole on the axle carrier and install the drum.
- If the adjuster was loosened to remove the drum, turn the adjuster bolt to adjust the length to the shortest possible amount.
- Install the rear wheels, tighten the lug nuts and lower the vehicle.
- Retighten the lug nuts and pump the brake pedal before moving the vehicle.
See Figures 6 and 7
- Clean the drum.
- Inspect the drum for scoring, cracks, grooves and out-of-roundness. Replace the drum or have it ""turned" at a machine or brake specialist shop, as required. Light scoring may be removed by dressing the drum with fine emery cloth.
- Measure the inside diameter of the drum. A tool called a H-gauge caliper is used. See the Brake Specifications chart for your vehicle.
