1. Lift the Vehicle Start by securely lifting the vehicle with a jack and supporting it with jack stands. Ensure that the vehicle is stable before proceeding.

2. Remove the Wheel Use the lug wrench to remove the wheel that covers the drum brake assembly. Place the wheel aside.

3. Remove the Brake Drum Depending on the model of your vehicle, you may need to remove retaining clips or screws from the drum. If the drum is stuck, a brake drum puller can assist in taking it off without damaging surrounding components.

4. Inspect Components Once the drum is removed, inspect the brake shoes, wheel cylinder, and drum for wear. Replace any components that show signs of excessive wear or damage.

5. Install New Brake Shoes When replacing the brake shoes, follow the manufacturer’s instructions carefully. Make sure the shoes are properly aligned and not pinched.

6. Reassemble the Brake Assembly With the new shoes in place, reinstall the brake drum. Ensure it spins freely without any obstruction. Reattach any clips or screws that were removed.

7. Reattach the Wheel Carefully place the wheel back on and secure it with lug nuts. Use the lug wrench to tighten them in a crisscross pattern to ensure even tightening.

8. Lower the Vehicle Once everything is reassembled, lower the vehicle back to the ground.

Final Checks

Before hitting the road, it’s critical to double-check your work. Press the brake pedal a few times to ensure the brake shoes seat correctly. Test drive your vehicle at a low speed to confirm everything is functioning properly.

Replacing drum brakes is a fundamental part of vehicle maintenance that enhances safety and performance. While the process may seem daunting, with the right tools and instructions, it can be a manageable task for many car enthusiasts. Regular maintenance and awareness of brake performance can prolong the life of your braking system and ensure a safer driving experience.
