How to Change Rear Drum Brakes

Changing rear drum brakes might seem like a daunting task if you're not familiar with vehicle maintenance, but with some basic tools and a bit of guidance, you can successfully complete this job at home. This article will walk you through the essential steps to change your rear drum brakes safely and efficiently.

Tools and Materials Needed

Before starting, gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Brake drum puller (optional) - Screwdrivers (flathead and Phillips) - Pliers - New brake shoes - Brake cleaner - Brake grease - Ruler or caliper - Safety glasses and gloves

Step 1 Safety First

Always prioritize safety when working on your vehicle. Start by parking your car on a flat surface and engaging the parking brake. Use wheel chocks behind the front wheels to prevent the vehicle from rolling. Put on safety glasses and gloves to protect yourself from dust and debris.

Step 2 Lift the Vehicle

Use a jack to lift the rear of the vehicle. Once it’s lifted, secure it with jack stands to ensure that it remains stable during the brake replacement process. Never work under a vehicle that is only held up by a jack.

Step 3 Remove the Wheel

Using a lug wrench, remove the lug nuts from the rear wheel you are working on. If the wheel is stuck, give it a few taps with a rubber mallet to loosen it. Once the nuts are removed, take off the wheel and set it aside.

Step 4 Inspect the Brake Assembly

Now that you have access to the brake assembly, it’s time to inspect the existing drums and shoes. Look for signs of wear, such as cracks or thinning in the brake shoes. If the shoes are worn down below the manufacturer's specifications, they need to be replaced.

Step 5 Remove the Brake Drum

Most brake drums can be removed by simply pulling them off. If they are stuck due to rust or corrosion, you may need to use a brake drum puller. Once the drum is off, take a moment to inspect the surface for any deep grooves or damage. If necessary, you can have the drum turned (machined) for a smoother surface or replace it entirely.

Step 6 Replace the Brake Shoes

To remove the old brake shoes, you’ll need to detach the retaining springs and any associated hardware. Use pliers or a screwdriver to carefully remove these components. When installing new shoes, it’s important to follow the configuration of the old shoes to ensure proper installation. Attach the new shoes to the backing plate, securing them with the hardware and retaining springs you removed earlier.

Step 7 Reinstall the Brake Drum

Once the new brake shoes are in place, carefully slide the brake drum back onto the wheel hub. Make sure it moves freely and isn’t binding against the shoes. If you find any resistance, double-check the installation of the brake shoes.

Step 8 Reattach the Wheel

With the drum securely in place, it’s time to put the wheel back on. Align the wheel with the lug bolts, and hand-tighten the lug nuts. Once the wheel is on, lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern to ensure an even torque.

Step 9 Test the Brakes

Before hitting the road, pump the brake pedal several times to seat the new shoes against the drum. This action is crucial for ensuring that the brake system functions effectively. After that, take your vehicle for a short test drive, preferably in an area with little traffic, to ensure that everything is working properly.

Conclusion

Changing rear drum brakes is a manageable task for those willing to put in the time and effort. By following these steps and adhering to safety practices, you can save money on labor costs and gain a sense of accomplishment. However, if you encounter any issues or feel unsure at any point, it’s always wise to consult a professional mechanic. Happy driving!
