How to Install Drum Brake Shoes A Step-by-Step Guide

Installing drum brake shoes is a crucial skill for any DIY mechanic or car enthusiast. Drum brakes are common in many vehicles, especially older models and some trucks. Proper installation not only ensures the safety of your vehicle but also enhances braking performance. This guide will walk you through the process step by step, ensuring you have all the information you need to complete the job successfully.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials

- New drum brake shoes - Brake cleaner - Wrenches and sockets - A jack and jack stands - A lug wrench - Brake spring tool - Screwdrivers (flathead and Phillips) - A bungee cord or rope (optional but helpful)

Step 1 Prepare the Vehicle

1. Safety First Park the vehicle on a flat surface, engage the parking brake, and wear appropriate safety gear, including gloves and eye protection.

2. Jack Up the Vehicle Loosen the lug nuts on the rear wheels slightly before raising the vehicle with a jack. Once elevated, securely place jack stands under the vehicle to ensure stability.

3. Remove the Wheel Finish loosening and removing the lug nuts, then take off the wheel to access the drum brake assembly.

Step 2 Remove the Brake Drum

1. Inspect the Drum Before removing the brake drum, check for any retaining screws or clips that may be holding it in place.

2. Remove the Drum If the drum is stuck due to rust or debris, gently tap around its edge with a rubber mallet to loosen it. Once free, slide the drum off the wheel hub.

Step 3 Take Out the Old Brake Shoes

1. Inspect the Assembly Familiarize yourself with how the brake shoes, springs, and hardware are assembled. This knowledge will help you during reinstallation.

2. Remove the Springs Using a brake spring tool or a pair of pliers, carefully detach the return and compression springs that hold the shoes in place. Take care to remember the arrangement as you will need to replace them later.

3. Remove the Shoes Once the springs are removed, detach the old brake shoes from the backing plate. Note the position of the adjuster and any other hardware for accurate reassembly.

Step 4 Install New Brake Shoes

1. Clean the Assembly Use brake cleaner to remove dust and debris from the backing plate and other components. This will ensure proper functioning and longevity of the new shoes.

2. Install New Shoes Position the new brake shoes onto the backing plate, aligning them with the adjuster and any necessary hardware. Make sure they fit securely into place.

3. Reattach the Springs Using your brake spring tool, reattach the compression and return springs to hold the shoes in position. Ensure they are snug, but take care not to overstretch them.

Step 5 Reassemble and Test

1. Replace the Brake Drum Slide the drum back over the newly installed brake shoes. If the shoes are properly adjusted, the drum should fit easily. If it is too tight, you may need to adjust the shoes by turning the adjuster that links them.

2. 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 fully tighten the lug nuts in a crisscross pattern.

3. Repeat on the Other Side If you are replacing the shoes on both sides, repeat the above steps for the other wheel.

4. Test Drive After the installation, take the vehicle for a slow test drive. Testing brakes at low speed ensures everything is functioning correctly. Listen for any unusual noises, and check that braking performance feels normal.

Conclusion

Installing drum brake shoes can seem daunting, but with the right tools and approach, it becomes a manageable task. Regular maintenance of your braking system not only improves performance but also enhances safety on the road. Always consult your vehicle’s manual for specific instructions related to your model, and when in doubt, don’t hesitate to seek professional help. Happy wrenching!
