Steps to Replace and Adjust Drum Brakes for Optimal Performance

How to Change a Drum Brake

Changing a drum brake may seem daunting, but with the right tools and a little guidance, it can be a manageable task even for novice mechanics. This article will guide you through the process, ensuring that you not only get the job done but also understand each step along the way.

Tools and Materials Needed

Before starting, gather the necessary tools and materials. You will need - A jack and jack stands - A lug wrench - A brake drum removal tool - A socket set and ratchet - A torque wrench - Brake cleaner - New brake shoes - Brake grease - Safety goggles and gloves

Step 1 Preparation

1. Safety First Ensure you’re working in a well-ventilated area. Wear safety goggles and gloves to protect yourself from dirt and debris. 2. Lift the Vehicle Park your car on a flat surface and loosen the lug nuts on the wheel where you will be changing the drum brake. Then, use the jack to lift the vehicle and secure it with jack stands.

3. Remove the Wheel With the vehicle securely lifted, remove the lug nuts completely and take off the wheel to access the brake drum.

Step 2 Remove the Brake Drum

1. Inspect the System Before removing the drum, inspect it for any signs of damage or wear. If the drum is excessively worn, it may need to be replaced.

2. Remove the Drum Depending on the vehicle, you may need to remove retaining screws or clips. If the drum is stuck, lightly tap it with a hammer to loosen it before pulling it off.

Step 3 Inspect and Replace the Brake Shoes

1. Examine the Brake Shoes With the drum removed, inspect the brake shoes for wear. If the lining is less than 1/8 inch thick, it’s time for a replacement.

2. Remove Old Shoes Take note of how the old shoes are arranged, including the positioning of springs and other components. Remove the tension springs and the shoes. A brake spring tool can assist with this task.

3. Clean the Components Use brake cleaner to remove dust and debris from the brake assembly and the drum itself. This will ensure optimal performance of the new brakes.

Step 4 Install New Brake Shoes

1. Position New Shoes Place the new brake shoes into the drum assembly in the same configuration as the old ones. Ensure they are facing the correct direction.

2. Reattach the Springs Use a brake spring tool to reattach the tension springs. Make sure they are secured properly to prevent any misalignment.

Step 5 Reassemble

1. Reinstall the Brake Drum Once the new shoes are in place, slide the drum back onto the assembly. Ensure it fits snugly and rotates freely.

2. Reattach the Wheel Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground before tightening the lug nuts completely using the torque wrench, according to the manufacturer’s specifications.

Step 6 Testing

1. Check the Brakes Pump the brake pedal several times to seat the shoes properly against the drum.

2. Test Drive Take a short test drive to ensure the brakes are functioning correctly. Listen for any unusual noises and pay attention to how the vehicle stops.

Conclusion

Changing drum brakes is a straightforward process if you follow each step carefully. Regular maintenance of your braking system is crucial for safety and performance. If you ever feel unsure, consulting a professional mechanic is always a wise choice. With practice, you’ll gain confidence in handling this task and more complex automotive repairs in the future.
