How to Change Drum Brakes

Changing drum brakes may seem like a daunting task, but with the right tools and some basic mechanical knowledge, it can be done at home. Drum brakes are commonly found on the rear wheels of many vehicles and consist of several key components, including the drum, shoes, springs, and hardware. This guide will walk you through the steps to change your drum brakes safely and effectively.

Tools and Materials Needed

Before starting, you'll need to gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Brake cleaner - Brake shoe kit (shoes, springs, hardware) - Screwdriver (flathead and Phillips) - Pliers - C-Clamp - Torque wrench - Safety goggles and gloves

Step 1 Prepare Your Vehicle

First, park your vehicle on a flat surface and engage the parking brake to prevent any movement. Loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground. This makes it easier to remove them once the car is jacked up.

Next, use the jack to lift the rear of the vehicle, placing jack stands under the vehicle for safety. Once secure, completely remove the loosened lug nuts and then slide off the rear wheels to expose the drum brakes.

Step 2 Remove the Brake Drum

With the wheels removed, you will see the brake drum. If the drum is stuck, you may need to tap it gently with a hammer to dislodge it. Be careful not to damage the drum. Once loose, slide the drum off to reveal the brake shoes and hardware.

Step 3 Inspect Components

Before proceeding, take a moment to inspect the brake components. Look for signs of wear on the brake shoes, springs, and hardware. If any components appear damaged or worn beyond acceptable limits, they should be replaced.

To remove the brake shoes, you will typically need to detach the springs and hold-down hardware. Start by using pliers to remove the retaining clips and springs. Make sure to note how everything is arranged, as you'll need to replicate this setup with the new shoes.

Once the springs are removed, you can lift the brake shoes off the mounting points. Be sure to keep track of the order in which you remove the components for easy reassembly.

Step 5 Install the New Brake Shoes

Now it’s time to install your new brake shoes. Begin by positioning the new shoes in the same arrangement as the old ones. Attach any hold-down springs or clips that you removed earlier. It’s crucial to ensure that all components are installed securely.

Step 6 Reassemble the Brake System

After securing the new shoes, reattach the return springs and ensure everything is properly seated. If your drum brake system includes a self-adjusting mechanism, make sure it’s set correctly. Use a C-clamp to compress the brake shoes slightly, making it easier to fit the drum back over the shoes.

Step 7 Reinstall the Brake Drum

With the new shoes in place, slide the brake drum back onto the hub. It should fit snugly but should not require excessive force. If it does not fit, double-check the alignment of the shoes and adjust if necessary.

Step 8 Reattach the Wheels

Once the drum is in place, put the wheels back on the vehicle and hand-tighten the lug nuts. Lower the vehicle off the jack stands and to the ground. Once the vehicle is secure, use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque settings.

Step 9 Test Your Brakes

Before hitting the road, pump the brake pedal a few times to ensure that the brake shoes are seated properly and that the brake system is functioning effectively. It’s also wise to conduct a short test drive to confirm that everything is working correctly.

Conclusion

Changing drum brakes may require some effort, but it is a manageable task for those willing to learn and work safely. Regular maintenance of your brake system is vital for vehicle safety, so be sure to check your brakes periodically and replace them when necessary. By following these steps, you'll gain confidence in your automotive skills while ensuring a safer ride.
