How to Change a Drum Brake A Step-by-Step Guide

Changing a drum brake may seem daunting, but with the right tools and instructions, it can be a straightforward task. Drum brakes are common in many vehicles, especially older models, and understanding the process can save you both time and money. Here’s a comprehensive guide to help you through changing a drum brake.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials

1. Tools - A jack and jack stands - Lug wrench - Brake drum puller (if needed) - Screwdrivers (flathead and Phillips) - Pliers - C-clamp or brake spring tool - Torque wrench

2. Materials - Replacement brake shoes - Brake drum (if necessary) - Brake lubricant - Brake cleaner - Safety gloves and goggles

Step-by-Step Instructions

Step 1 Prepare Your Vehicle

1. Safety First Park your vehicle on a flat surface, engage the parking brake, and wear safety gloves and goggles to protect yourself. 2. Loosen the Lug Nuts Using a lug wrench, loosen the lug nuts on the wheel corresponding to the drum brake you’re replacing. Make sure not to remove them entirely yet.

3. Lift the Vehicle Use the jack to lift the vehicle and then secure it with jack stands. Make sure the vehicle is stable before going underneath it.

Step 2 Remove the Wheel

1. Take Off the Wheel Once the vehicle is secure, remove the loosened lug nuts completely and take off the wheel. This will expose the drum brake assembly.

Step 3 Remove the Brake Drum

1. Inspect the Drum Check if the brake drum is held tightly. Tap around the edge with a rubber mallet to see if it loosens. If it doesn’t budge, you may need a brake drum puller.

2. Take Off the Drum Once loose, pull the drum towards you. If it doesn't come off easily, check for any securing screws that may need to be removed.

1. Remove the Springs Using pliers or a brake spring tool, remove the small springs securing the brake shoes to the backing plate. Keep note of the arrangement, as this will help during reassembly.

2. Take Off the Brake Shoes Pull the brake shoes away from the backing plate. If they are stuck, gently rock them back and forth until they come free.

Step 5 Install the New Brake Shoes

1. Compare Old and New Shoes Before installation, compare the old brake shoes with the new ones to ensure they are the correct size and type.

2. Install New Shoes Begin replacing the shoes by fixing the new ones to the backing plate. Reattach the springs in the same way they were removed, ensuring everything is tight and secure.

Step 6 Replace the Brake Drum

1. Reattach the Drum Carefully slide the brake drum back onto the hub. Ensure it rotates freely without dragging on the new brake shoes.

2. Adjust the Shoes (if necessary) Some drum brakes have an adjustment mechanism that needs to be tightened or loosened to ensure the shoes are correctly spaced from the drum.

Step 7 Reinstall the Wheel

1. Put on the Wheel Place the wheel back on, hand-tightening the lug nuts.

2. Lower the Vehicle Remove the jack stands and carefully lower the vehicle back to the ground.

3. Tighten the Lug Nuts Once on the ground, use the torque wrench to tighten the lug nuts to the manufacturer-recommended specifications.

Step 8 Final Checks

1. Test the Brakes Before driving, pump the brake pedal a few times to seat the new brake shoes against the drum properly.

2. Check for Leaks Inspect the brake system for any leaks or issues.

Conclusion

Changing a drum brake can be a rewarding DIY project. By following these steps, you not only save on labor costs but also gain a better understanding of your vehicle's braking system. Always consult your vehicle's service manual for specific instructions and torque specifications. If you encounter any complications, it is advisable to seek help from a certified mechanic. With the right care and maintenance, your new drum brakes will provide you with reliable stopping power for many miles to come.
