Jeep Wrangler/YJ 1987-1995 Repair Guide

Brake Drums



Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

The brake drums are held in position by spring clip type locknuts or by three drum-to-hub retaining screws, depending on the model and year. After the spring type locknuts or retaining screws are removed, the drum can be slid off the axle shaft or hub and brake shoes. It may be necessary to back off the brake shoe adjustment so that any lip on the inside of the brake drum clears the brake shoes.


Using a brake drum micrometer, check all drums. Should a brake drum be scored or rough, it may be reconditioned by grinding or turning on a lathe. Do not remove more than 0.030 in. (0.8mm) thickness of metal.

Use a clean cloth to clean dirt from the brake drums. If further cleaning is required, use soap and water. Do not use brake fluid, gasoline, kerosene or any other similar solvents.
