How to Remove a Stuck Rear Brake Drum

Removing a stuck rear brake drum can be a daunting task for many DIY enthusiasts, but with the right tools and techniques, you can do it safely and effectively. This guide will walk you through the steps to remove a stuck rear brake drum from your vehicle.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- Jack and jack stands - Lug wrench - Brake drum puller (optional) - Inner brake tool (if necessary) - Hammer - Penetrating oil (such as WD-40) - Safety goggles - Gloves

Step-by-Step Guide

1. Preparation and Safety First

Begin by ensuring your vehicle is parked on a flat surface with the parking brake engaged. Wear safety goggles and gloves to protect yourself during the process.

2. Loosen the Lug Nuts

Using a lug wrench, slightly loosen the lug nuts on the rear wheels. Do not fully remove them yet, as the vehicle should not be lifted with loose lug nuts.

3. Lift the Vehicle

Use a jack to lift the rear of the vehicle. Once elevated, place jack stands under the vehicle to ensure it is secure and will not fall while you work.

4. Remove the Wheels

Now that the vehicle is stable, fully remove the loosened lug nuts and take off the rear wheels. This will expose the brake drums.

5. Inspect the Brake Drum

Take a close look at the brake drum for any obvious signs of damage or corrosion. If the drum is excessively corroded, it may be easier to replace it rather than attempting to remove it.

6. Apply Penetrating Oil

Spray a liberal amount of penetrating oil around the edges of the brake drum where it meets the wheel hub. Allow it to sit for at least 10-15 minutes to penetrate and loosen any rust or debris keeping the drum stuck.

7. Use a Hammer to Tap

Gently tap around the brake drum with a hammer. Start at one edge and work your way around the drum. The vibrations from the tapping can help break the bond between the drum and the hub. Be careful not to hit too hard, as you could damage the drum.

8. Use a Brake Drum Puller (Optional)

If the drum is still stuck after tapping, you may want to consider using a brake drum puller. This tool is specifically designed to pull the drum off without causing damage. Follow the manufacturer’s instructions for the proper use of the puller.

9. Check for Adjustment

If you have drum brakes, ensure that the brake adjuster is not too tight. Sometimes, the adjuster can cause the brake shoes to expand and make it difficult to remove the drum.

10. Final Attempts

If all else fails, reapply penetrating oil, let it sit again, and repeat the tapping process. In some instances, it may take multiple attempts and patience to free the drum.

Conclusion

Removing a stuck rear brake drum may require some effort and time, but by following these steps, you can successfully complete the task. Remember to work safely and cautiously, and don’t hesitate to consult a professional mechanic if you encounter difficulties. Regular maintenance and inspection of your braking system can also help prevent a stuck brake drum in the future.
