The Ultimate Guide on How to Replace Drum Brakes

When it comes to vehicle maintenance, ensuring your brakes are in top condition is paramount for your safety and the safety of others on the road. While disc brakes are more commonly found in modern vehicles, drum brakes are still prevalent in many cars, particularly older models and certain light-duty vehicles. If you’ve noticed a squealing sound when braking or a decrease in braking performance, it may be time to replace your drum brakes. Follow this ultimate guide to navigate the process with confidence.

Tools and Materials Needed

Before starting the replacement process, gather the following tools and materials

- Jack and jack stands - Socket set - Brake spring tool - Flathead and Phillips screwdrivers - Needle-nose pliers - Brake cleaner - New brake shoes - New drum (if necessary) - Protective gloves and eyewear - Torque wrench

Step-by-Step Guide

Step 1 Safety First

Park your vehicle on a level surface and engage the parking brake. It's essential to prevent any movement while you work. Wear protective gloves and eyewear to safeguard against any sharp edges or brake dust.

Step 2 Raise the Vehicle

Using the jack, lift the vehicle and securely place it on jack stands. Never rely solely on the jack to hold the vehicle up. Remove the wheel to gain access to the drum brakes.

Step 3 Remove the Brake Drum

Inspect the drum for any retaining screws. If present, remove them using the appropriate screwdriver. If the drum is stuck due to rust or wear, gently tap around the edges with a hammer to loosen it. Once free, slide the drum off the hub—this may require some effort if it's been in place for a while.

Step 4 Inspect the Components

After removing the drum, visually inspect the brake assembly. Check the condition of the wheel cylinder, springs, and brake shoes. Look for any leaks or wear. If the brake shoes are worn down to the limit or if there’s any sign of damage, they need replacing.

Step 5 Remove the Brake Shoes

Carefully remove the brake shoes by detaching the springs and other hardware. Using a brake spring tool will make it easier to remove and reinstall the springs without injury. Take note of how everything is arranged, or take a picture for reference during reassembly.

Step 6 Prepare for Installation

Clean the brake assembly with brake cleaner to remove any dust and debris. Inspect the drum for scoring or damage—if any is found, replace the drum. Ensure the surface is smooth for optimal brake performance.

Step 7 Install New Brake Shoes

Begin installing the new brake shoes in the reverse order of removal. Attach the primary shoe (the one with the shorter lining) and then the secondary shoe. Reinstall the springs and connect any other hardware, ensuring everything is secure. Use the brake spring tool for proper installation.

Step 8 Reattach the Brake Drum

Once the new brake shoes are in place, slide the brake drum back onto the hub. Ensure that it rotates freely without any binding. If it seems too tight, double-check the positioning of the shoes and adjust if necessary.

Step 9 Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle back onto the ground and then use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 10 Final Checks

Before hitting the road, pump the brake pedal a few times to seat the new brake shoes against the drum. Check the brake fluid level and ensure there are no leaks. It’s crucial to test the brakes at a low speed before driving normally to ensure they function properly.

Conclusion

Replacing drum brakes may seem like a daunting task, but with the right tools, materials, and steps outlined in this guide, DIY enthusiasts can tackle it confidently. Regular brake maintenance not only enhances your vehicle's performance but it also ensures your safety on the road. If you are ever in doubt about your skills, don't hesitate to consult a professional mechanic. Drive safely!
