How to Rebuild Rear Drum Brakes

Rebuilding rear drum brakes is an important maintenance task that can significantly improve your vehicle's braking performance and longevity. It may seem daunting, but with the right tools and a bit of guidance, you can tackle this project yourself. Here’s a step-by-step guide to help you rebuild your rear drum brakes.

Tools and Materials Needed

Before you start, gather the necessary tools and materials. You’ll need - A jack and jack stands - A lug wrench - A brake drum puller (if necessary) - Brake cleaner - A brake kit (including new shoes, hardware, and springs) - A socket set and wrenches - A screwdriver - A C-clamp or brake spring tool - Safety glasses and gloves

Step 1 Safety First

Always prioritize safety when working on vehicles. Park your car on a level surface, engage the parking brake, and wear safety glasses and gloves.

Step 2 Remove the Rear Wheels

Using the lug wrench, loosen the lug nuts on the rear wheels, but don't remove them completely. Then, use the jack to lift the vehicle and secure it with jack stands. Fully remove the lug nuts and take off the rear wheels to expose the brake drums.

Inspect the brake drums for any signs of rust or wear. If they are secured with retaining screws, remove them. You may need a brake drum puller if the drum is difficult to remove. Lightly tap around the drum's edges with a hammer if necessary, or use the puller to help detach it from the hub.

Step 4 Inspect and Clean

Once the drums are off, inspect the brake shoes, springs, and other components for wear or damage. Use brake cleaner to clean the inside of the drums thoroughly. If the shoes are worn down significantly (generally less than 1/8 inch remaining), they need to be replaced.

Step 5 Replace the Brake Shoes

Carefully remove the old brake shoes by unhooking the springs and any retaining clips. Install the new brake shoes by attaching them in the same configuration as the old ones, ensuring that they sit correctly on the backing plate. Use a C-clamp or brake spring tool to help with this process, making sure not to overstretch the springs.

Step 6 Reassemble Components

Once the new shoes are in place, install the new hardware and springs that came in the brake kit. Pay attention to the orientation of each part, as they need to be assembled correctly for optimal function.

Step 7 Reinstall the Brake Drums and Wheels

Now that your new brake shoes and components are installed, slide the brake drums back onto the spindles. Make sure they rotate freely without binding. Reinstall the wheels and hand-tighten the lug nuts before lowering the vehicle back to the ground.

Step 8 Final Checks

After lowering the vehicle, torque the lug nuts to the manufacturer’s specifications using the lug wrench. Before driving, pump the brake pedal several times to seat the new brake shoes against the drums.

Conclusion

Rebuilding rear drum brakes can seem like an intimidating task, but with careful attention to detail and the right tools, you can efficiently complete the job. Regular maintenance and timely replacements can enhance your vehicle's safety and performance, giving you confidence on the road. Always consult your vehicle’s manual for specifics, and don't hesitate to seek professional help if you're unsure about any step in the process.
