#### INSPECTION

1. Clean the drum.
2. 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.

3. Measure the inside diameter of the drum. A tool called a H-gauge caliper is used. See the Brake Specifications chart for your vehicle.
