Replacing Rear Drum Brakes A Step-by-Step Guide

Rear drum brakes play a crucial role in the overall braking system of a vehicle. They are less common in modern vehicles, which often employ disc brakes, but many older cars, trucks, and some economy models still use drum brakes in the rear. As with all automotive components, wear and tear can lead to diminished braking performance. Thus, knowing how to replace rear drum brakes is an invaluable skill for any car owner or DIY enthusiast. This article will guide you through the process of replacing rear drum brakes, ensuring you maintain your vehicle’s safety and drivability.

Tools and Materials Needed

Before beginning the replacement process, gather the necessary tools and materials - Jack and jack stands - Lug wrench - Brake drum puller (if necessary) - Screwdrivers (flathead and Phillips) - Pliers - Brake cleaner - New brake shoes - Hardware kit (if recommended) - C-clamp - Torque wrench (optional)

Safety First

Safety is paramount when working on your vehicle. Make sure to wear gloves and safety glasses, and ensure your car is parked on a flat surface. Engage the parking brake and wear appropriate clothing that won’t get caught in any moving parts.

Step 1 Preparation

Start by loosening the lug nuts of the rear wheels while the car is still on the ground. This will make it easier to remove the wheels once the vehicle is lifted.

Step 2 Lifting the Vehicle

Using the jack, lift the rear of the vehicle and securely place jack stands under the frame. Once the vehicle is stable, remove the rear wheels to access the brake drums.

With the wheels removed, inspect the drums. If they’re stuck due to rust or debris, you may need a brake drum puller. If not, simply pull the drum off the hub. If there are any retaining screws, use a screwdriver to remove them first.

Step 4 Inspecting Components

Before replacing the shoes, take the time to inspect the brake pads, springs, and the drum itself for wear and damage. If the drum is scored or excessively worn, you may need to replace it or have it turned. Check the shoes for any cracks, wear, or contamination.

Step 5 Removing Old Brake Shoes

Remove the old brake shoes by disconnecting the springs and retaining clips. Use pliers for any stubborn parts, but be careful not to damage any components that you plan to reuse. Keep track of how everything is assembled; taking a picture before disassembly can help you reassemble it correctly.

Step 6 Installing New Shoes

Before installing your new brake shoes, apply brake cleaner to the backing plate and any reused components to remove grease and dust. Install the new brake shoes, following the original configuration. Ensure that all the springs and clips are securely reattached. This is important for the correct functioning of your rear brakes.

Step 7 Reinstalling the Brake Drum

Once the new shoes are installed, carefully slide the brake drum back over the shoes. It should fit snugly; if it doesn’t, verify that all components are seated properly and that the shoe adjustment is correct.

Step 8 Adjusting the Brake Shoes

After you install the drum, adjust the brake shoes so that they barely touch the drum. This step ensures that your brakes are effective without dragging on the drum.

Step 9 Reattaching Wheels

With the brake drum and shoes installed, reattach the rear wheels and hand-tighten the lug nuts before lowering the car back to the ground. Once the car is secured, use the lug wrench to tighten the lug nuts in a crisscross pattern for even distribution.

Step 10 Testing the Brakes

Before taking your vehicle out on public roads, it's crucial to test the brakes. Start the engine and pump the brake pedal several times to engage the new shoes with the drum. Then, perform a low-speed test drive to ensure everything functions as it should.

Conclusion

Replacing rear drum brakes might seem daunting, but with the right tools and a methodical approach, it can be a straightforward task. Regular maintenance of your braking system is essential for safe driving. If at any point you feel unsure about the process, don’t hesitate to seek professional assistance. Your safety, and that of others on the road, is always the top priority. Happy repairing!
