Changing Brake Shoes on Drum Brakes A Step-by-Step Guide
Changing brake shoes on drum brakes is a vital maintenance task that can enhance the performance of your vehicle's braking system. While it may seem daunting, with the right tools and some guidance, you can successfully replace your brake shoes. This article will walk you through the essential steps to perform this task safely and effectively.
Understanding Drum Brakes
Drum brakes are a common braking system used in many vehicles, especially in the rear brakes. They consist of a drum that rotates with the wheel, and brake shoes that press against the inner surface of the drum to create friction and slow down the vehicle. Over time, brake shoes wear down due to constant friction, necessitating a replacement to ensure safe driving conditions.
Tools and Materials Needed
Before starting, gather the necessary tools and materials - A jack and jack stands - A lug wrench - A brake shoe replacement kit (including new shoes and any hardware needed) - A brake cleaner - A socket set and ratchet - Pliers - A flathead screwdriver - Safety goggles and gloves
Step-by-Step Guide to Changing Brake Shoes
1. Safety First Park your vehicle on a flat surface and engage the parking brake. Wear safety goggles and gloves throughout the process.
2. Remove the Wheel Use the lug wrench to loosen the lug nuts, then lift the vehicle using the jack. Secure it on jack stands and completely remove the lug nuts before taking off the wheel.
3. Inspect the Brake Assembly With the wheel removed, you will see the brake drum. Look for any signs of fluid leaks or damage in the brake assembly.
4. Remove the Brake Drum If the drum is stuck, gently tap it with a rubber mallet to loosen it. Carefully slide the drum off the hub. If you encounter resistance, check for retaining screws or clips that may need removal.
5. Remove the Old Brake Shoes Take a moment to examine how the old shoes are configured, as you'll want to replicate this during reinstallation. Use pliers to disconnect the return springs and any other hardware holding the shoes in place. Gently pull the shoes away from the backing plate.
6. Clean the Brake Assembly Use brake cleaner to remove dust and debris from the brake assembly. Ensure that no dirt settles in the drum or components.
7. Install New Brake Shoes Begin by attaching the new brake shoes to the backing plate. Connect the adjusting lever, return springs, and any other hardware according to the configuration of the old shoes. Make sure everything is securely fastened.
8. Reattach the Brake Drum Slide the brake drum back onto the hub, ensuring it fits snugly without any obstruction. If there is excessive resistance, recheck the orientation of the brake shoes and adjust if needed.
9. Reinstall the Wheel Place the wheel back onto the hub, hand-tighten the lug nuts, lower the vehicle from the jack stands, and then fully tighten the lug nuts in a star pattern.
10. Test the Brakes Before driving, pump the brake pedal a few times to ensure proper contact between the shoes and the drum. Check for any unusual noises or issues.
Conclusion
Changing brake shoes on drum brakes may seem complex, but by following these steps and taking the necessary precautions, you can perform this task efficiently. Regular maintenance of your braking system is crucial for vehicle safety and performance. If at any point you feel uncomfortable with the process, don’t hesitate to consult with a professional mechanic. Safe driving starts with well-maintained brakes!
