How to Change Drum Brakes A Step-by-Step Guide

Changing drum brakes is an essential skill for any car owner or DIY enthusiast. While it may seem daunting at first, with the right tools and a little guidance, you can perform this task efficiently. This article will provide a step-by-step guide on how to change drum brakes safely and effectively.

Tools and Materials Needed

Before beginning, gather the necessary tools and materials. You will need

1. Brake drum service tool or a hammer 2. Socket set 3. Wrench set 4. Screwdrivers 5. Brake cleaner 6. New brake shoes 7. Brake grease 8. Safety goggles and gloves 9. Jack and jack stands

Step 1 Preparation

Start by preparing your workspace. Ensure the car is parked on a level surface, and engage the parking brake. Wear safety goggles and gloves to protect yourself while working.

Step 2 Loosing the Lug Nuts

If you're changing the brakes on a rear wheel, use a lug wrench to slightly loosen the lug nuts on the rear wheel but do not completely remove them. If applicable, you may need to lift the rear of the vehicle using a jack. Secure the vehicle with jack stands for safety.

Step 3 Remove the Wheel

Once the vehicle is lifted and securely supported, remove the lug nuts completely and take off the wheel. This will expose the brake drum.

Step 4 Inspect the Brake Drum

Before removing the drum, inspect it for any obvious signs of damage or wear. If the drum appears warped or has deep grooves, it may need to be resurfaced or replaced.

Step 5 Remove the Brake Drum

If the drum does not come off easily, tap around the edges with a hammer to loosen it. You can also use a brake drum puller if necessary. Once loose, slide the drum off.

Step 6 Remove Old Brake Shoes

Take note of how the old brake shoes are installed for reference. Remove the retaining springs and any clips holding the shoes in place. Carefully take out the old shoes and inspect the hardware for wear. Replace any components that are not in good condition.

Step 7 Install New Brake Shoes

Before installing the new brake shoes, clean the backing plate using brake cleaner. Then, apply brake grease to the contact points on the backing plate. Install the new brake shoes following the configuration of the old ones, ensuring that the springs and clips are attached securely.

Step 8 Reinstall the Brake Drum

Once the new shoes are in place, slide the brake drum back onto the hub. Make sure it spins freely. If it doesn’t, double-check that the shoes are properly aligned.

Step 9 Reattach the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then fully tighten the lug nuts in a criss-cross pattern to ensure an even fit.

Step 10 Test the Brakes

Before driving, pump the brake pedal a few times to seat the new shoes against the drum. Check for any unusual noises or issues. It’s important to take a short test drive at low speeds to ensure everything is functioning correctly.

Final Thoughts

Changing drum brakes may require some patience, but following these steps can help simplify the process. Always prioritize safety when working on your vehicle and consult a professional mechanic if you feel unsure about any step. Regular brake maintenance is vital for safe driving, so don't hesitate to keep your braking system in optimal condition.
