Removing Rusted Brake Drums A Step-by-Step Guide

Brake drums are crucial components of a vehicle's braking system, primarily found in older cars or specific models using drum brakes. Over time, exposure to moisture, road salt, and debris can cause these drum brakes to rust, leading to poor braking performance, increased stopping distances, and potential safety hazards. If you find yourself facing rusted brake drums, this article will guide you through the process of safely removing them.

Tools and Materials Needed

Before starting, gather the necessary tools and materials - Jack and jack stands - Lug wrench - Brake drum puller - Hammer and punch - Wire brush - WD-40 or penetrating oil - Safety goggles - Gloves

Preparation

1. Safety First Begin by engaging the parking brake of your vehicle and placing wheel chocks behind the wheels remaining on the ground. This ensures the vehicle remains stable during the process.

2. Loosen the Lug Nuts Using the lug wrench, slightly loosen the lug nuts on the wheel associated with the rusted brake drum. Do not remove them completely yet.

3. Lift the Vehicle Use the jack to raise the vehicle to a safe height, and then place jack stands to support it securely. Once the vehicle is stable, fully remove the lug nuts and take off the wheel to expose the brake drum.

Inspect the Brake Drum

Before attempting to remove the drum, inspect it for any additional issues. Look for deep grooves, cracks, or severe rust damage that may indicate a need for replacement rather than removal for cleaning.

Remove the Rusted Brake Drum

1. Apply Penetrating Oil Generously spray WD-40 or another penetrating oil around the edges of the brake drum. This will help loosen any rust and corrosion that may have caused it to bond to the wheel hub.

2. Tap the Drum After allowing the penetrating oil to sit for a few minutes, take a hammer and a punch to gently tap around the face of the drum. This vibration can help break the bond created by rust. Avoid using excessive force, as you don't want to damage any components.

3. Use a Brake Drum Puller If the drum does not budge after tapping, it may be time to use a brake drum puller. This tool attaches to the drum and utilizes a threaded shaft to pull the drum off the hub. Position it according to the manufacturer’s instructions, and tighten it gradually. Be cautious; some force will be needed, but excessive pressure can lead to damage.

4. Remove the Drum Once sufficiently loosened, pull the drum off. You may need to rotate it slightly as you pull it to free it from the shoes. If it still resists, double-check for any retaining screws or clips that might be holding it in place.

Cleaning or Replacement

Once the drum is removed, assess its condition. If it’s not severely damaged, you can clean it using a wire brush to remove rust and debris. However, if the drum is extensively pitted or cracked, it’s best to replace it with a new one for optimal safety and performance.

Reassembly

After cleaning or replacing the drum, reverse the disassembly steps - Reinstall the drum, ensuring it fits snugly. - Reattach the wheel and tighten the lug nuts in a star pattern to ensure even distribution. - Lower the vehicle and remove the jack stands. - Tighten the lug nuts fully once the vehicle is back on the ground.

Conclusion

Removing rusted brake drums can be a straightforward task if approached methodically. Always prioritize safety, and don’t hesitate to seek professional help if you encounter difficulties. Regular maintenance and inspections can prevent rust buildup in the first place, ensuring your vehicle remains safe and roadworthy.
