How to Change Brake Drums A Step-by-Step Guide

Brake drums are a critical component of a vehicle's braking system, particularly in older models and certain types of heavy-duty vehicles. Over time, brake drums can wear out, leading to decreased braking efficiency and potentially dangerous driving conditions. Changing brake drums is a task that many DIY enthusiasts can handle with the right tools and knowledge. In this article, we will guide you through the process of changing brake drums step by step, ensuring that you can do it safely and effectively.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- Jack and jack stands - Lug wrench - Brake drum puller (if necessary) - New brake drums - Brake shoes (optional, but recommended) - Brake cleaner - C-clamp or brake tool - Socket set and ratchet - Torque wrench

Step 1 Prepare Your Vehicle

1. Safety First Park your vehicle on a flat, stable surface, and engage the parking brake. You may also want to place wheel chocks behind the rear wheels for added safety. 2. Loosen the Lug Nuts Use the lug wrench to slightly loosen (but not remove) the lug nuts on the rear wheels. This will make it easier to remove the wheel later.

Step 2 Lift the Vehicle

1. Jack Up the Vehicle Position the jack under the manufacturer-recommended jacking point and lift the rear of the vehicle off the ground.

2. Secure with Jack Stands Once the vehicle is elevated, place jack stands under the vehicle for safety. Never rely solely on the jack.

Step 3 Remove the Wheel

1. Remove the Lug Nuts Now that the vehicle is secure, fully remove the loosened lug nuts and take off the wheel. Set it aside in a safe location.

Step 4 Access the Brake Drum

1. Inspect the Brake Assembly Take a moment to inspect the brake assembly for any visible wear or damage. If you're changing the brake drums, it’s often advisable to change the brake shoes as well.

2. Remove the Brake Drum If the drum is stuck, you may need to use a brake drum puller. If it pulls off easily, great! If not, gently tap around the edge with a rubber mallet to loosen it.

Step 5 Change the Brake Shoes (Optional but Recommended)

1. Remove Old Brake Shoes If you're changing the brake shoes, use a C-clamp or brake tool to compress the springs and detach them carefully.

2. Install New Brake Shoes Position the new brake shoes into place, ensuring they align properly with the backing plate and the new drum.

Step 6 Install New Brake Drums

1. Clean the Surface Before installing the new drum, use brake cleaner to wipe down the surface and ensure there’s no grease or debris. This helps prevent squeaks and ensures smooth operation.

2. Install the New Brake Drum Slide the new brake drum onto the hub, making sure it’s seated evenly. Rotate the drum a bit to ensure it moves freely.

Step 7 Reassemble

1. Reattach the Wheel Place the wheel back onto the hub, lining up the holes with the lug bolts. Hand-tighten the lug nuts as much as possible.

2. Lower the Vehicle Carefully lift your jack to remove the jack stands and let the vehicle back down to the ground.

3. Tighten the Lug Nuts Once on the ground, use your torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 8 Final Checks

1. Pump the Brakes Before driving, pump the brake pedal a few times to ensure the brake shoes and drums are properly seated.

2. Test Drive Finally, take your vehicle for a short test drive to ensure everything is working correctly. Listen for any unusual noises and check the responsiveness of the brakes.

Conclusion

Changing brake drums might seem challenging, but with the right tools and this guide, it can be a straightforward process. Always remember to prioritize safety and consult your vehicle's manual for specific recommendations. If you find yourself unsure at any step, don't hesitate to consult a professional mechanic. Regular maintenance of your brake system is crucial for safe driving, so stay proactive!
