How to Replace Brake Drums A Step-by-Step Guide
Replacing brake drums is a critical part of vehicle maintenance that ensures your safety on the road. Over time, brake drums can wear down, leading to reduced braking efficiency and increased stopping distances. Knowing how to replace them can save you time and money while boosting your vehicle’s performance. Here’s a step-by-step guide to help you safely and effectively replace your brake drums.
Tools and Materials Needed
Before starting the process, gather the following tools and materials
- New brake drums - Brake shoes - Brake cleaner - A jack and jack stands - A lug wrench - A socket set - A screwdriver - A pony wrench or brake spring tool - Gloves and safety goggles
Step 1 Prepare Your Vehicle
1. Safety First Park your vehicle on a flat surface and engage the parking brake. If working on a rear axle, use wheel chocks to prevent movement. 2. Loosen Lug Nuts Use a lug wrench to loosen the lug nuts on the rear wheels slightly, but do not fully remove them yet.
3. Lift the Vehicle Use a jack to lift the rear of the vehicle off the ground and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 2 Remove the Wheels
1. Remove Lug Nuts Now that the vehicle is elevated and secured, use the lug wrench to completely remove the lug nuts and take off the wheels. Keep the lug nuts in a safe place for later use.
Step 3 Disassemble the Brake Components
1. Inspect the Assembly Before removing anything, take a moment to inspect the brake assembly. This will give you an idea of how everything is put together.
2. Remove the Brake Drum There might be retaining screws securing the drum. If they exist, use a screwdriver to remove them. Gently tap the drum if it's stuck, but avoid using excessive force.
3. Access the Brake Shoes Once the drum is off, the brake shoes should be visible. Take note of how the components are arranged; taking a picture can help you remember the configuration for reassembly.
Step 4 Remove the Old Brake Shoes
1. Disconnect Springs and Clips Use a brake spring tool to carefully remove the springs and clips holding the old brake shoes in place. Be cautious, as they may snap back.
2. Take Out the Shoes Once the springs are removed, the brake shoes should come off easily. Inspect them for wear before disposing of them.
Step 5 Install New Brake Shoes
1. Position New Shoes Place the new brake shoes in the same configuration as the old ones. Ensure that they are seated properly.
2. Reattach Springs and Clips Use the brake spring tool to reattach the springs and clips, securing the new shoes in place.
Step 6 Replace the Brake Drum
1. Clean the Drum Before placing the new drum on, clean the inside surface with brake cleaner to avoid contamination.
2. Install the New Drum Slide the new brake drum onto the wheel hub. Ensure that it sits flush and is free from debris.
Step 7 Reassemble the Wheel
1. Put the Wheel Back On Place the wheel back onto the hub and hand-tighten the lug nuts in a star pattern to ensure even tightening.
2. Lower the Vehicle Carefully lower the vehicle back to the ground using the jack and remove the jack stands.
3. Tighten Lug Nuts Once on the ground, use the lug wrench to fully tighten the lug nuts in the same star pattern.
Conclusion
Replacing brake drums can be a straightforward process with the right tools and careful attention to detail. After completing the job, remember to pump the brake pedal a few times to ensure proper engagement before driving. Regular maintenance and timely replacements will help ensure your vehicle remains safe and reliable on the road. If you ever feel unsure, it’s always best to consult with a professional mechanic. Safe driving!
