How to Replace Drum Brakes A Step-by-Step Guide

Replacing drum brakes may seem intimidating, but with the right tools and a little patience, you can do it yourself. This guide will walk you through the steps required to replace drum brakes on most vehicles, ensuring safety and performance when you're done. Always remember that if you're unsure about any part of the process, consulting a professional mechanic is a wise choice.

Tools and Materials Needed

Before you get started, it’s crucial to gather all the necessary tools and materials - Tools - Jack and jack stands - Lug wrench - Brake spring tool - Screwdriver set - Pliers - Torque wrench - A clean workspace - Materials - Replacement drum brake shoes - New drums, if necessary - Brake lubricant - Brake cleaner

Step 1 Safety First

1. Park on a Level Surface Ensure you park your vehicle on a flat, stable surface. Engage the parking brake. 2. Loosen Lug Nuts Before raising the vehicle, use the lug wrench to slightly loosen the lug nuts on the wheel you will be working on. Do not remove them yet.

Step 2 Raise the Vehicle

1. Jack Up Your Vehicle Use a jack to lift the vehicle and then secure it on jack stands. Never rely solely on the jack for support. 2. Remove the Wheel Completely remove the lug nuts and take off the wheel to access the drum.

Step 3 Remove the Drum

1. Inspect the Drum Look for any obvious signs of damage. If the drum is scored or damaged, it’s better to replace it. 2. Detach the Drum If the drum is stuck, use a hammer to gently tap the edges. This can help loosen any rust or debris holding it in place. Once loose, pull it off the wheel hub.

Step 4 Examine the Brake Assembly

1. Check Components Inspect the brake shoes, springs, and wheel cylinder for wear and tear. Replace any components that are damaged or excessively worn. 2. Take Photos Before disassembling anything, take detailed photos of the current setup. This will help as a reference when you reassemble the brakes.

Step 5 Remove Old Brake Shoes

1. Remove Springs Use the brake spring tool to detach the springs from the brake shoes. Be cautious; spring tension can make them fly off unexpectedly. 2. Take Off Brake Shoes Once the springs are removed, slide the old brake shoes off the anchor points.

1. Position New Shoes Take the new brake shoes and position them in the same configuration as the old ones, using your reference photos if necessary. 2. Reattach Springs Secure the springs back onto the new shoes, ensuring everything is tight and correctly aligned.

Step 7 Reinstall Drum

1. Lubricate Contact Points Apply brake lubricant to the contact points, avoiding the friction surface of the shoes and drum. 2. Reattach Drum Carefully slide the drum back onto the hub. It should fit snugly without excessive force. 3. Install the Wheel Place the wheel back onto the vehicle and hand-tighten the lug nuts.

Step 8 Lower the Vehicle

1. Remove Jack Stands Once everything is secured, carefully jack up the vehicle slightly to remove the jack stands. 2. Lower the Vehicle Slowly lower the vehicle back to the ground.

Step 9 Torquing the Lug Nuts

Once the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque rating, usually found in the owner’s manual.

Step 10 Test the Brakes

Before hitting the road, pump the brake pedal several times to ensure the brake shoes seat properly against the drum. Take a short test drive to check for unusual noises or issues.

Conclusion

Replacing drum brakes is a manageable task with the right tools and a systematic approach. Regular maintenance not only extends the life of your brakes but also ensures your safety on the road. If at any point you feel unsure or uncomfortable, do not hesitate to reach out to a professional. Happy driving!
