1. Park the vehicle on a level surface and engage the parking brake.
2. Loosen the lug nuts on the rear wheels, but do not remove them completely.
3. Jack up the rear of the vehicle and support it on jack stands.
4. Remove the lug nuts and take off the wheels.
5. Locate the brake drum retaining screws or bolts. There may be two or four of these, depending on the model.
6. Remove the retaining screws or bolts and pull the brake drum off of the axle flange.
If the brake drum is stuck, you may need to use a pry bar to pry it off. Be careful not to damage the brake shoes or the brake drum.
Once the brake drum is removed, you can access the brake shoes and other brake components for inspection or repair.
