How to Remove Rusted Drum Brakes


Rusted drum brakes can present a significant challenge when it comes to maintenance and repair. They not only affect the performance of your vehicle but can also be a formidable obstacle if you need to replace or inspect them. Here, we'll go through a step-by-step process on how to effectively remove rusted drum brakes.


Tools and Materials Needed


Before you begin, gather the following tools and materials


- Adjustable wrench or socket set - Screwdriver (flathead and Phillips) - Hammer - Brake cleaner - Rust penetrant (like WD-40) - Safety goggles - Gloves - Pliers - Jack and jack stands


Step 1 Safety First


Ensure your vehicle is parked on a level surface. Activate the parking brake and wear safety goggles and gloves for protection. Use a jack to lift the rear or front end of the vehicle, depending on which brakes you are working on. Once elevated, secure the vehicle with jack stands.


Step 2 Remove the Wheel


Using the appropriate socket or wrench, take off the lug nuts from the wheel and remove the wheel from the hub. This will expose the brake drum.


Step 3 Inspect the Brake Drum


Look for signs of rust or any other damage on the brake drum. If the drum is excessively corroded, it may be best to replace it. If it's merely rusted, you can proceed to remove it.


Step 4 Apply Rust Penetrant

Spray a generous amount of rust penetrant around the edges of the drum where it meets the backing plate. Allow it to sit for at least 10-15 minutes to penetrate the rust.


Step 5 Remove the Drum


After the penetrant has soaked in, gently tap the drum using a hammer. Begin by tapping from the back of the drum near the adjustment hole and work your way around the circumference. Be cautious not to hit too hard, as this could damage other components.


If the drum still doesn't budge, you may need to adjust the brake shoes. Locate the adjuster (usually found through a small access hole in the backing plate) and turn it to loosen the shoes. This will create more space for the drum to come off.


Step 6 Cleaning


Once the drum is removed, it's time to clean the brake components. Use a brake cleaner to remove any dust, debris, and leftover rust from the shoes and backing plate. This step is crucial for optimal braking performance.


Step 7 Inspect and Replace


Examine the brake shoes for wear. If they are worn down, it’s advisable to replace them while you have everything apart. Also, inspect the drum for scoring or deep rust; if the surface is damaged beyond a safe level, replace the drum as well.


Step 8 Reassemble


Once you’ve completed any necessary repairs or replacements, reassemble the brakes. Ensure everything is tightened to the manufacturer's specifications and reinstall the wheel.


Final Thoughts


Working on rusted drum brakes can be tedious, but with patience and the right tools, you'll find it manageable. Regular maintenance and inspections can help prevent rust and prolong the life of your brake components. If you ever feel overwhelmed or uncertain, don't hesitate to consult a professional mechanic for assistance. Remember, safety and thoroughness are key when it comes to any vehicular maintenance.
