How to Remove Rusted Brake Drum A Step-by-Step Guide

Removing a rusted brake drum can be a daunting task for many car owners, but with the right tools and techniques, it can be accomplished successfully. Brake drums can become corroded due to moisture, road salt, and other environmental factors, making removal difficult. In this article, we will guide you through the process of removing rusted brake drums safely and efficiently.

Tools and Materials Needed

Before you begin, it's essential to gather the necessary tools and materials

- Lug wrench - Jack and jack stands - Brake cleaner - Rust penetrant (like WD-40) - Hammer - Pry bar or drum puller - Socket set and ratchet - Safety goggles and gloves

Step 1 Preparation

The first step in removing a rusted brake drum is to ensure you have a safe working environment. Begin by parking your vehicle on a level surface and engaging the parking brake. Put on your safety goggles and gloves to protect yourself from debris and sharp edges.

Step 2 Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel covering the brake drum you need to remove. It’s typically easier to do this before the vehicle is lifted. Once the lug nuts are loosened, use a jack to lift the vehicle and place it securely on jack stands. After the vehicle is elevated, finish removing the lug nuts and take off the wheel.

Step 3 Inspect the Brake Drum

With the wheel removed, take a moment to inspect the brake drum for any visible damage or excessive rust. Sometimes, a thorough cleaning might be sufficient; however, if the drum is excessively worn or damaged, it may need replacement.

Step 4 Apply Rust Penetrant

Spray a generous amount of rust penetrant around the edges and bolt areas of the brake drum. Allow it to sit for about 10-15 minutes to penetrate the rust. This will make it easier to detach the drum from the backing plate.

Step 5 Remove Retaining Fasteners

Some brake drums are secured with retaining screws or clips. Check for any fasteners that may need to be removed before attempting to pull the drum off. Use the appropriate socket to remove these fasteners.

Step 6 Tap and Pull

Using a hammer, gently tap around the edge of the brake drum to help break the rust bond. Be cautious not to hit too hard, as this could damage the drum. After tapping, try to pull the drum straight off. If it doesn't come off easily, use a pry bar to carefully pry it from the backing plate. If the drum is still stubborn, consider using a drum puller for added leverage.

Step 7 Clean the Area

Once the brake drum is removed, clean the wheel hub and the backing plate with brake cleaner. This will remove any dirt, debris, or rust that could affect the installation of a new drum or brake components.

Step 8 Install New or Resurfaced Drum

If you have a new or resurfaced brake drum, position it on the hub and align it with the bolt holes. Reinstall the retaining fasteners if applicable. Tighten them securely but avoid overtightening.

Step 9 Reassemble the Wheel

Carefully replace the wheel, hand-tighten the lug nuts and then lower the vehicle. Once on the ground, use the lug wrench to tighten the nuts completely in a crisscross pattern for even tightening.

Conclusion

Removing a rusted brake drum requires patience and care, but with the proper approach, you can accomplish it. Always adhere to safety practices and consider consulting a professional mechanic if you're unsure about any step in the process. Keeping your brakes in good condition is crucial for safe driving, and addressing rust promptly can help prevent more significant issues down the line.
