Steps for Replacing Drum Brakes on Your Vehicle Easily and Effectively

How to Change a Drum Brake

Changing drum brakes might seem like a daunting task, but with the right tools and a little patience, it can be an achievable DIY project. Whether you’re working on your own vehicle or just interested in learning how it's done, this guide will walk you through the process step by step, ensuring your drum brakes are replaced safely and correctly.

Tools and Materials Required

Before you begin, make sure you have the following tools and materials

- Jack and jack stands - Lug wrench - Brake cleaner - Brake grease - New brake shoes - Drum brake expansion tool (optional) - Screwdrivers (flathead & Phillips) - Pliers - A clean rag

Step 1 Safety Precautions

Safety should always come first. Park your vehicle on a flat surface, engage the parking brake, and put wheel chocks behind the wheels that you will not be working on. Wear safety goggles and gloves to protect yourself from dirt, debris, and brake dust.

Step 2 Lifting the Vehicle

Using the lug wrench, loosen the lug nuts on the rear wheels slightly (but don’t remove them yet). Then, use the jack to lift the vehicle off the ground. Secure it with jack stands to ensure it’s stable while you work.

Step 3 Removing the Wheel

Now that your vehicle is safely elevated, remove the lug nuts completely and take off the wheel. Set the wheel aside in a safe location, as you’ll need to reattach it later.

With the wheel removed, you'll see the brake drum. Before removing it, check for any retaining screws that may be holding the drum in place. Using your screwdriver, remove any screws or clips. If the drum appears stuck, it may be due to corrosion or brake shoe contact; gently tap the drum with a rubber hammer to loosen it, then pull it off.

Step 5 Inspecting Components

Before installing the new brake shoes, take a moment to inspect the brake drum and other components. Look for any signs of wear or damage, such as grooves in the drum. If the drum looks damaged, you may need to have it machined or replaced. Ensure that the brake cylinder, springs, and any other hardware are in good condition.

Step 6 Removing Old Brake Shoes

Once the drum is off, you can proceed to remove the old brake shoes. Take careful note of how the old shoes are positioned, as this will help you install the new ones correctly. Use your pliers to disconnect the springs and any retaining clips holding the shoes in place.

Step 7 Installing New Brake Shoes

Now it’s time to install the new brake shoes. Start by positioning the new shoes in the same configuration as the old ones. Attach the springs and retaining clips while ensuring everything fits securely. It’s crucial to apply grease to the backing plates where the shoes will make contact to allow for smooth operation.

Step 8 Reinstalling the Brake Drum

Carefully slide the drum back onto the axle, ensuring it fits over the new brake shoes without interference. Reattach any screws or clips that were removed, and ensure the drum spins freely without excessive resistance.

Step 9 Reattaching the Wheel

Now that your brake drum is secured, it’s time to put the wheel back on. Place the wheel onto the hub and hand-tighten the lug nuts. Once the wheel is back in place, lower the vehicle back to the ground and then tighten the lug nuts in a crisscross pattern to ensure even tightening.

Step 10 Testing

Before taking your vehicle back on the road, pump the brakes a few times to ensure the shoes are properly seated against the drum. This action helps restore hydraulic pressure in the brake system. Finally, take a short drive at low speeds to ensure everything is functioning correctly, listening for any unusual noises.

Conclusion

Changing drum brakes is a manageable task for those who are reasonably handy with tools. With patience, attention to detail, and following the steps outlined above, you can successfully change your drum brakes and ensure your vehicle is safe to drive. Always consult your vehicle’s manual for specific details tailored to your model. If at any point you feel uncertain, don’t hesitate to seek professional help. Happy driving!
