How to Replace Rear Drum Brakes A Comprehensive Guide

Replacing rear drum brakes is an important maintenance task that every DIY mechanic should feel comfortable tackling. This procedure can help ensure your vehicle’s braking system operates efficiently, ultimately contributing to your safety on the road. Below, we will go through the step-by-step process of replacing rear drum brakes.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- New brake shoes - Brake drum - Brake lubricant - Brake cleaner - A jack and jack stands - Lug wrench - Socket wrench set - Screwdriver set - Pliers - A bungee cord or rope

Step 1 Safety First

Before you start working on your vehicle, ensure that it is parked on a flat surface and the parking brake is engaged. Wear safety glasses and gloves to protect yourself from debris and sharp objects.

Step 2 Loosen the Wheel Lug Nuts

Using a lug wrench, slightly loosen the lug nuts on the rear wheels of your vehicle before raising it. This will make it easier to remove the wheels once the vehicle is on jack stands.

Step 3 Raise the Vehicle

Using a jack, lift the vehicle until it is high enough to comfortably work underneath. Once elevated, secure it with jack stands to prevent it from falling. Ensure the vehicle is stable before proceeding.

Step 4 Remove the Wheels

Now, completely remove the loosened lug nuts and take off the rear wheels. Set them aside in a safe place to avoid damaging them.

Step 5 Inspect the Brake System

Before proceeding with the replacement, take a moment to inspect the brake components. Check the condition of the brake drums, and make sure there are no significant grooves or damage. If the drums are worn or damaged, they may need to be replaced as well.

Step 6 Remove the Brake Drum

To remove the brake drum, locate the retaining screws (if applicable) and remove them. If the drum is stuck due to rust or wear, gently tap it with a rubber mallet to loosen it. Once free, slide the drum off the wheel hub.

Step 7 Remove Old Brake Shoes

Observe how the old brake shoes are connected, as you will need to replicate this setup when installing new shoes. Use a socket wrench to remove the anchor bolts and springs holding the shoes in place. Carefully detach the shoes from their mounting points. Be cautious of the springs, as they can snap back when detached.

Step 8 Install the New Brake Shoes

Take your new brake shoes and install them in the same configuration as the old ones. Secure them in place using the anchor bolts and springs. Make sure everything is tight but not over-tightened, allowing the shoes to move freely.

Step 9 Clean and Inspect the Brake Drum

Before reassembling, clean the inside of the new brake drum with brake cleaner to remove any grease or debris. Inspect the drum for any signs of wear or damage. If it looks good, you can proceed to reattach it.

Step 10 Reinstall the Brake Drum

Slide the cleaned or new drum over the newly installed brake shoes. If necessary, replace the retaining screws to secure the drum.

Step 11 Reattach the Wheel

Place the wheel back onto the wheel hub and hand-tighten the lug nuts to hold it in place. After this, lower the vehicle back to the ground and use the lug wrench to tighten the lug nuts fully in a crisscross pattern to ensure an even fit.

Step 12 Test Drive

Once everything is reassembled, take your vehicle for a short test drive in a safe area. Test the brakes to ensure they are functioning properly. Listen for any unusual noises and pay attention to how the brakes respond.

Conclusion

Replacing your rear drum brakes is not just a task for professionals; it’s something you can do at home with the right tools and a bit of patience. Following these steps will not only save you money but will also give you a sense of accomplishment. Always refer to your vehicle's manual for specific instructions related to your model, and don’t hesitate to consult a professional if you encounter any problems. Keeping your brakes in good condition is crucial for your driving safety.
