How to Replace Rear Brake Drums

Replacing rear brake drums is an essential maintenance task for vehicle owners, especially for those with drum brake systems. Over time, brake drums can wear out, leading to reduced braking performance and safety issues. This guide will walk you through the process of replacing rear brake drums, ensuring your vehicle operates safely and efficiently.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials

- New brake drums - Brake shoes (if needed) - Brake cleaner - Wrench set - Screwdrivers (flat and Phillips) - Jack and jack stands - Lug wrench - Torque wrench - Safety goggles and gloves

Step 1 Prepare Your Vehicle

Start by parking your vehicle on a level surface and engaging the parking brake. Wear safety goggles and gloves to protect yourself during the process.

1. Loosen the Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the rear wheels. Do not remove them completely yet. 2. Lift the Vehicle Using a jack, lift the rear of the vehicle and secure it with jack stands to ensure it is stable and safe to work on.

3. Remove the Wheels Once the vehicle is safely elevated, remove the lug nuts completely and take off the rear wheels to access the brake drums.

Step 2 Remove the Brake Drums

With the wheels removed, it’s time to take off the brake drums.

1. Inspect the Brake Assembly Look at the brake shoes and other components. If they appear worn or damaged, consider replacing them along with the drums.

2. Remove the Drum In some cases, the brake drum may be stuck due to rust or debris. If this happens, gently tap the drum with a hammer to loosen it. Avoid applying excessive force, as this could damage the drum or the wheel hub.

3. Take Off the Drum Once loose, pull the drum straight off the wheel hub. Keep track of any small components, such as springs or clips, that may fall off during removal.

Step 3 Install the New Brake Drums

1. Clean the Wheel Hub Before installing new drums, clean the wheel hub using brake cleaner to remove any dirt or old grease.

2. Install New Brake Shoes (if applicable) If you’re replacing the brake shoes, install them according to the manufacturer’s instructions. Make sure all springs and clips are correctly positioned and secured.

3. Mount the New Brake Drum Slide the new brake drum onto the wheel hub. Ensure it fits snugly and rotates freely without any obstruction.

Step 4 Reassemble and Test

1. Reattach the Wheels Place the wheels back on the drum and hand-tighten the lug nuts.

2. Lower the Vehicle Carefully remove the jack stands and lower the vehicle back to the ground.

3. Tighten Lug Nuts Once the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the vehicle manufacturer's specifications. This step ensures that the wheels are secured properly.

4. Test the Brakes Before heading out on the road, pump the brake pedal a few times to seat the new brake shoes against the drum. This action also helps to restore brake fluid pressure. Check for any unusual noises or issues while testing the brakes.

Conclusion

Replacing rear brake drums may seem daunting, but it’s a manageable task for those who are willing to learn and take proper precautions. Regular brake maintenance not only enhances your vehicle’s safety but also extends the lifespan of your braking system. Always consult your vehicle’s manual for specific instructions and specifications, and when in doubt, seek assistance from a professional mechanic. Happy driving!
