How to Replace Rear Brake Drums

Replacing rear brake drums is an essential maintenance task that can help ensure your vehicle stops safely and efficiently. Brake drums are found on the rear wheels of many cars and trucks and are crucial for the vehicle's braking system. Over time, these components can wear out, leading to decreased braking performance or even brake failure. Here’s a step-by-step guide to help you replace rear brake drums safely and effectively.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials - New brake drums - Brake shoes (if needed) - Brake cleaner - A lug wrench - A jack and jack stands - A socket set - A drum brake tool kit (optional) - Safety goggles and gloves

Step 1 Ensure Safety

Safety should always be your top concern when working on your vehicle. Begin by parking the car on a level surface and engaging the parking brake. Wear safety goggles and gloves to protect yourself from dust and debris.

Step 2 Loosen the Lug Nuts

Using a lug wrench, loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground. Do not remove them completely yet.

Step 3 Lift the Vehicle

After loosening the lug nuts, use a jack to lift the rear of the vehicle. Make sure to place jack stands under the vehicle to ensure it is securely elevated. This step is crucial for your safety while working underneath the car.

Step 4 Remove the Wheels

Once the vehicle is securely lifted, remove the lug nuts completely and take off the wheels, exposing the brake drums.

Step 5 Inspect the Brake Assembly

With the brake drums exposed, take a moment to inspect the brake assembly. Look for signs of wear on the brake shoes, springs, and other components. If the brake shoes are worn down, you will need to replace them along with the drums.

Step 6 Remove the Brake Drums

To remove the brake drums, you may need to tap them lightly with a hammer if they are stuck due to rust or residue. Gently pull the drum straight off the hub. If the drums are equipped with adjusting screws, you may need to adjust them to allow for easier removal.

Step 7 Install New Brake Drums

Before installing the new brake drums, clean the brake assembly with brake cleaner to remove any dust or debris. When ready, slide the new brake drum onto the wheel hub. It should fit snugly but should not require excessive force to install.

Step 8 Reassemble the Brake System

If you replaced the brake shoes, carefully reinstall them according to the manufacturer's specifications. Make sure all springs and retainers are properly attached. Adjust the shoes according to the instructions to ensure proper contact with the drum.

Step 9 Reinstall the Wheels

Once everything is in place and you've ensured the brake system is properly assembled, place the wheels back on. Hand-tighten the lug nuts to secure the wheels.

Step 10 Lower the Vehicle

Using the jack, carefully lower the vehicle back to the ground. After it’s on the ground, use the lug wrench to tighten the lug nuts fully in a star pattern to ensure even tightening.

Step 11 Test the Brakes

Before driving the vehicle, pump the brake pedal a few times to seat the brake shoes against the drums. This is crucial, as it helps restore brake pressure before you hit the road.

Conclusion

Replacing rear brake drums is a manageable task that can extend the lifespan of your braking system and ensure safer driving conditions. By following these steps, you can efficiently perform this maintenance task with the right tools and knowledge. If you encounter any complications or have doubts, it is advised to consult a professional mechanic.
