How to Replace Rear Drum Brakes A Step-by-Step Guide

Replacing rear drum brakes is a vital skill for any car enthusiast or those looking to save money on auto repairs. Understanding this process not only ensures your vehicle operates safely but also enhances your knowledge of automotive maintenance. This guide provides a detailed, step-by-step approach to replacing rear drum brakes.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials - Jack and jack stands - Lug wrench - Drum brake service kit (new brake shoes, springs, and hardware) - Brake cleaner - Screwdriver (flat-head and Phillips) - Pliers - Torque wrench - Brake shoe retainers

Step 1 Ensure Safety

Begin by ensuring your vehicle is parked on a flat surface. Engage the parking brake and wear safety glasses and gloves. Loosen the lug nuts on the rear wheels slightly, but do not remove them yet.

Step 2 Lift the Vehicle

Using a jack, lift the rear of the vehicle and secure it on jack stands. Make sure it's stable before proceeding. Now, you can remove the lug nuts completely and take off the rear wheels.

Step 3 Remove the Drum

Inspect the drum and, if necessary, the retaining screws must be removed. If the drum is stuck due to rust or debris, gently tap it with a hammer to loosen it. Once free, slide the drum off and set it aside.

Step 4 Inspect Components

With the drum removed, check the condition of the brake shoes, springs, and hardware. Note how everything is positioned, as you will need to replicate this arrangement when installing the new components. Take pictures if necessary.

Step 5 Remove Old Brake Shoes

To remove the old brake shoes, start by detaching any retaining springs using pliers. Carefully note the removal order of the springs and hardware since they will need to be reused or replaced. With the springs removed, you can take off the brake shoes, which should come off easily if the springs are out.

Before proceeding with the installation of new parts, clean the brake assembly. Use brake cleaner to remove any dust, debris, or oil, ensuring a clean surface for the new components.

Step 7 Install New Brake Shoes

Take your new brake shoes from the service kit and install them in the same configuration as the old ones. Start by placing the shoe with the larger lining on the rear side (the primary shoe), and the smaller one on the front (the secondary shoe). Reinstall the retaining hardware and springs carefully, ensuring all components are secure.

Step 8 Reattach the Brake Drum

Once the new shoes are in place, slide the drum back over the brake assembly. Ensure it fits snugly over the shoes. If it doesn’t fit, you may need to adjust the brake adjuster to allow for proper clearance.

Step 9 Reassemble the Wheel

With the drum secured, place the rear wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle from the jack stands and tighten the lug nuts in a crisscross pattern using a torque wrench to the manufacturer’s specifications.

Step 10 Test the Brakes

Before hitting the road, pump the brake pedal a few times to seat the new shoes and springs. This step is crucial for ensuring effective braking when driving.

Conclusion

Replacing rear drum brakes may seem daunting, but with the right tools, materials, and steps, it becomes a manageable DIY task. Regular maintenance will prolong the life of your brakes and ensure safe driving conditions. Always consult your vehicle’s service manual for specific guidance tailored to your car model. Happy braking!
