How to Change Drum Brake Shoes A Comprehensive Guide

Changing drum brake shoes is a crucial maintenance procedure that helps ensure the safety and performance of your vehicle. While many car owners may feel intimidated by this task, with the right tools and a step-by-step approach, changing brake shoes can be done by anyone with a basic understanding of car mechanics. This guide will provide you with a detailed overview of the entire process.

Tools and Materials Needed

Before you start, gather the following tools and materials

- New brake shoes - Brake cleaner - A jack and jack stands - A lug wrench - A brake shoe tool or spring tool - A socket set - A flathead screwdriver - A torque wrench - Gloves and eye protection

Step 1 Prepare the Vehicle

1. Safety First Ensure the vehicle is parked on a level surface and turn off the ignition. Engage the parking brake and make sure the car is stable.

2. Loosen the Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the wheel you will be working on, but do not remove them entirely. This will save you effort when the car is lifted.

3. Lift the Vehicle Use a jack to raise the vehicle and securely place jack stands underneath for safety. Then, remove the lug nuts and take off the wheel.

Step 2 Access the Brake Assembly

1. Remove the Drum Depending on your vehicle model, you may need to use a flathead screwdriver to gently pry the drum off, or it may come off easily once the wheel is removed. Inspect the drum for any signs of wear or damage.

2. Inspect the Old Shoes Take a moment to observe the condition of the old brake shoes. If they appear worn down, cracked, or glazed, it’s a clear sign that they need replacement.

Step 3 Disassemble the Brake Components

1. Remove Springs Use a brake shoes tool or a spring tool to carefully remove the retaining springs and adjuster lever. Be cautious, as these components are under tension and can snap back unexpectedly.

2. Take off the Old Shoes Once the springs are removed, slide the old shoes off the anchor pin and disengage them from the adjuster mechanism.

3. Clean the Brake Assembly Before installing new shoes, clean the brake assembly with brake cleaner to remove dust and debris. This will ensure optimal performance and longevity for the new components.

Step 4 Install New Brake Shoes

1. Position the New Shoes Align the new brake shoes in the same configuration as the old ones. Ensure they are correctly positioned on the anchor pin and fit into the adjuster mechanism properly.

2. Reattach Springs Carefully reattach the retaining springs. It’s best to do this one at a time, ensuring that everything is seated correctly before moving to the next spring. This requires patience and a steady hand to avoid damaging the springs.

Step 5 Reassemble the Brake System

1. Replace the Drum Once the new shoes are in place, reinstall the brake drum. It should fit snugly over the new shoes.

2. Reattach the Wheel Place the wheel back on the hub, hand-tighten the lug nuts, and lower the vehicle back onto the ground. Once on a level surface, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 6 Final Checks

1. Test the Brake Pedal It’s important to pump the brake pedal a few times to seat the new shoes against the drum before driving. This ensures proper braking response.

2. Inspect Take a moment to inspect the brake assembly and ensure that everything is fitted correctly, with no loose parts or tools left behind.

Conclusion

Changing drum brake shoes can seem daunting, but with careful preparation and attention to detail, it is a manageable task. Always refer to your vehicle's service manual for specific instructions related to your model, and if you're uncertain at any point, don’t hesitate to consult a professional mechanic. Regular maintenance of your brake system can greatly improve your vehicle's safety and performance, ensuring you drive with confidence.
