Steps for Installing Drum Brake Shoes on Your Vehicle

How to Install Drum Brake Shoes A Step-by-Step Guide

Drum brakes are a common braking system used in many vehicles, especially older models and some SUVs. While disc brakes have become more popular, drum brakes are still effective when properly maintained. Over time, the brake shoes in a drum braking system will wear down and need replacement. Installing drum brake shoes may seem daunting, but with the right tools and some basic mechanical knowledge, you can do it yourself. In this article, we’ll walk you through the steps to install drum brake shoes safely and effectively.

Tools and Materials Needed

Before diving into the installation process, make sure you have the following tools and materials

- New brake shoes - Brake cleaner - C-clamp or brake tool - Screwdriver (flathead and Phillips) - Wrench set - Pliers - Rubber mallet - Torque wrench - Safety glasses and gloves - Jack and jack stands

Step 1 Safety First

Before starting any work on your vehicle, ensure you are in a safe environment. Park the vehicle on a flat, level surface and engage the parking brake. Wear safety glasses and gloves to protect your eyes and hands.

Step 2 Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel where you will work. Once they are loose, use a jack to lift the vehicle and securely place it on jack stands. Completely remove the lug nuts and take off the wheel to expose the brake drum.

If the brake drum doesn’t come off easily, you may need to remove the retaining screws or use a rubber mallet to gently tap around the drum to free it. Use a brake cleaner to clean the outer surface of the drum and inspect for damage or wear. If the drum is scored or warped, it may need to be resurfaced or replaced.

Step 4 Inspect and Remove Old Brake Shoes

Look at the old brake shoes. If they are worn down to the metal or have uneven wear, it’s time for a replacement. Take a note of how the old shoes are installed, either by taking photos or making sketches to refer back to during installation.

To remove the old brake shoes, you will need to disconnect the retaining springs and any adjustment mechanisms using a screwdriver and pliers. Remember to keep any parts that are still in good condition for potential reuse.

Step 5 Prepare the New Brake Shoes

Before installing the new brake shoes, clean the brake assembly with brake cleaner to remove dust and debris. Make sure the contact surfaces are free from grease or oil. This is a good time to inspect the brake hardware (like springs and retainers) for wear. If anything looks damaged, replace it.

Step 6 Install the New Brake Shoes

Using your reference photos or sketches, install the new brake shoes in the reverse order of how the old ones were removed. Start by connecting the brake shoes to the backing plate, ensuring they are properly aligned. Reattach any springs, using a C-clamp or brake tool as needed to compress them.

Step 7 Reassemble the Drum Brake

Once the brake shoes are in place, carefully reattach the brake drum. Make sure it spins freely. If it feels tight, check to see if the shoes are adjusted properly. There should be a slight drag when spinning the drum, indicating proper contact.

Step 8 Replace the Wheel and Lower the Vehicle

Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle off the jack stands and back onto the ground. Once the vehicle is secure, tighten the lug nuts in a crisscross pattern to ensure even tightening.

Step 9 Test the Brakes

Before hitting the road, it’s crucial to test your brakes. Pump the brake pedal several times to position the shoes against the drum properly. This step ensures that the brake shoes are correctly aligned and ready for operation.

Conclusion

Installing drum brake shoes may seem like a complicated task, but by following these steps carefully, you can achieve a successful installation. Regular maintenance of your braking system is essential for your safety and the longevity of your vehicle. If at any point you feel unsure about the process, don’t hesitate to consult a professional mechanic for advice. With practice, you'll gain confidence and skill in maintaining your vehicle's braking system.
