How to Replace Drum Brakes

Replacing drum brakes is an essential skill for any car enthusiast or DIY mechanic. Understanding how to perform this task not only saves you money on labor costs but also gives you a deeper appreciation for your vehicle. This guide will walk you through the process step by step, ensuring safety and effectiveness.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials. You will need

1. Jack and Jack Stands For lifting the vehicle securely. 2. Lug Wrench To remove the wheel. 3. Drum Brake Tool Kit This may include spring tools, brake shoe spreaders, and a line wrench. 4. Replacement Brake Shoes Ensure you have the correct shoes for your vehicle. 5. Brake Cleaner To clean the brake drum and other components. 6. Grease For lubricating moving parts. 7. Safety Gear Gloves and goggles for protection.

Step-by-Step Guide

1. Safety First Begin by parking your vehicle on a flat surface. Ensure the parking brake is engaged. For extra safety, place wheel chocks behind the front wheels if you’re working on the rear brakes.

2. Remove the Wheel Use the lug wrench to loosen the lug nuts slightly while the wheel is still on the ground. Once loose, lift the vehicle with the jack and place it on jack stands. After securing the vehicle, remove the lug nuts and take off the wheel.

3. Remove the Brake Drum Inspect the drum for retaining screws. If present, remove them. Gently pull the drum off the hub. If it’s stuck due to corrosion, tap it lightly with a hammer, being careful to avoid damaging the drum.

4. Inspect Components Once the drum is removed, check the condition of the brake shoes, springs, and wheel cylinder. If the shoes appear worn unevenly or are thinner than the manufacturer’s specifications, they need replacement. Take note of how the components are arranged, as this will help during reassembly.

5. Remove Old Shoes Using your brake tool kit, remove the springs and clips holding the shoes in place. You might need a brake shoe spreader to take tension off the springs. Carefully detach the shoes from the backing plate.

6. Clean the Drum and Components Use brake cleaner to thoroughly clean the interior of the drum, the backing plate, and any other components in the area. Remove any dust and debris to ensure optimal performance.

7. Install New Shoes Position the new brake shoes in the same configuration as the old ones. Reattach the springs and clips according to the arrangement you noted earlier. Ensure everything is tight and secure, but be mindful not to overtighten which could damage the components.

8. Reassemble the Brake Drum Carefully place the drum back onto the hub. If you had retaining screws, replace them. Spin the drum to ensure it moves freely without dragging against the shoes.

9. Reinstall the Wheel Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground and then tighten the lug nuts in a star pattern to ensure even pressure.

10. Test the Brakes Before taking the vehicle out on the road, pump the brake pedal several times. This action seats the brake shoes against the drum and ensures they are functioning properly.

11. Final Inspection Take a moment to inspect your work. Ensure that all tools are removed from the vehicle, and double-check that all parts are secure.

Conclusion

Replacing drum brakes can seem daunting at first, but with the right tools and a clear understanding of the process, it is a manageable task. Remember that safety is paramount—always work with the vehicle securely lifted and never hesitate to seek assistance if you're unsure. Regular maintenance, like changing brake shoes, ensures your vehicle remains safe on the road, prolonging its life and enhancing performance. Happy wrenching!
