How to Get Stuck Brake Drums Off

Getting stuck brake drums off can be a challenging task for both DIY enthusiasts and seasoned mechanics. When brake drums become stuck due to rust, moisture, or improper installation, it can hinder your ability to perform necessary brake maintenance. Here’s a comprehensive guide on how to safely and effectively remove stuck brake drums.

Step 1 Safety First

Before beginning any repair work, ensure you take the proper safety precautions. Always wear safety glasses and gloves, and work in a well-ventilated area. Make sure the vehicle is on a flat surface, and use wheel chocks to prevent any movement.

Step 2 Gather Your Tools

To successfully remove stuck brake drums, gather the following tools - A jack and jack stands - A lug wrench - A hammer or mallet - Brake drum puller (if available) - Pliers - WD-40 or penetrating oil - A wire brush

Step 3 Loosen the Lug Nuts

Begin by loosening the lug nuts on the affected wheel while the vehicle is still on the ground. It’s easier to do this when the wheel is stable. Use the lug wrench to turn the nuts counterclockwise.

Step 4 Raise the Vehicle

Once the lug nuts are loosened, use the jack to lift the vehicle off the ground. Place jack stands under the vehicle to ensure it is securely supported. Never work underneath a vehicle that is only supported by a jack.

Step 5 Remove the Wheel

Now that the vehicle is safely elevated, remove the wheel entirely. With the wheel off, you should have access to the brake drum.

Before attempting to remove the brake drum, inspect it for any visible signs of damage or excessive rust. If it appears severely corroded, it may require special attention or replacement instead of just removal.

Step 7 Apply Penetrating Oil

Use WD-40 or another penetrating oil around the axle hub where the brake drum meets. Allow it to soak for about 10-15 minutes. This oil can help break down rust and debris that may be contributing to the sticking.

Step 8 Use a Hammer or Mallet

Gently tap around the edges of the brake drum using a hammer or mallet. Be careful not to strike too hard, as excessive force can cause damage. The goal is to break any rust bonds that may have formed.

Step 9 Using a Brake Drum Puller

If the drum remains stuck despite your efforts, consider using a brake drum puller. This tool applies even pressure and can help dislodge the drum without causing damage. Follow the manufacturer's instructions for proper use.

Step 10 Check the Adjustment

After successfully removing the drum, check the brake shoes and adjust them if necessary. They may be too tight against the drum, leading to the sticking issue in the first place.

Conclusion

Removing stuck brake drums can be a labor-intensive process, but with the right tools and techniques, it’s achievable. Always remember to prioritize safety and consult a professional mechanic if you encounter any difficulties or if you're unsure about any part of the process. Regular maintenance of your brake system is crucial for safe driving, so don't hesitate to perform this task when needed.
