How to Restore Drum Brakes A Step-by-Step Guide
Drum brakes are a reliable and efficient braking system commonly found in older vehicles and some modern models, especially in the rear. Over time, however, they may wear down due to environmental factors, regular wear and tear, or lack of maintenance. Restoring drum brakes can significantly enhance your vehicle's safety and performance. Here’s a comprehensive guide on how to restore drum brakes effectively.
Tools and Materials Needed
Before you begin the restoration process, gather the necessary tools and materials. You'll need - A jack and jack stands - A lug wrench - A brake cleaner - New brake shoes - A drum brake spring tool - A socket set - A flathead screwdriver - A pair of pliers - Torque wrench (optional)
Step 1 Safety First
Always prioritize safety when working on your vehicle. Park your car on a level surface and engage the parking brake. Wearing safety glasses and gloves is recommended to protect your eyes and hands from dust and debris.
Step 2 Remove the Wheel
Use a lug wrench to loosen the lug nuts before raising the vehicle. Once the car is lifted with the jack, remove the lug nuts completely and take off the wheel to access the drum brake assembly.
Step 3 Inspect the Drum
Before proceeding, inspect the drum for any visible signs of damage or wear. Look for scoring or grooves on the surface. If the drum is severely worn or damaged, it may require resurfacing or replacement.
Step 4 Remove the Brake Drum
To remove the brake drum, locate the retaining screws (if applicable) and remove them. Gently pull the drum off the wheel hub. If it’s stuck, a gentle tap with a hammer may help. Be cautious not to damage the drum.
Step 5 Examine the Brake Shoes
With the drum removed, take a close look at the brake shoes. If they are worn down (typically less than 1/4 inch thick), they will need to be replaced. Unhook the retaining springs using the brake spring tool and remove the old brake shoes carefully.
Step 6 Install New Brake Shoes
Install the new brake shoes by following the manufacturer’s instructions. Make sure to properly position the shoes and reattach the retaining springs correctly using the tool. Pay attention to the correct orientation of the shoes; the larger shoe typically goes on the rear.
Step 7 Reassemble the Drum
Once the new shoes are in place, carefully reinstall the brake drum. Ensure it fits snugly and rotates freely. If necessary, replace the retaining screws.
Step 8 Reattach the Wheel
Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground and then torque the lug nuts to the manufacturer’s specifications.
Conclusion
Restoring drum brakes may seem daunting, but with the right tools and a methodical approach, you can enhance your vehicle's braking performance. Regular maintenance will ensure your brakes serve you well for years to come. If you're uncertain during any step, don’t hesitate to consult a professional mechanic for assistance. Safe travels!
