How to Replace Rear Drum Brake Pads

Replacing rear drum brake pads can seem like a daunting task, especially if you’ve never done it before. However, with the right tools, a bit of patience, and this guide, you can successfully complete the job yourself. Here’s a step-by-step process to help you replace your rear drum brake pads efficiently.

Tools and Materials Needed

1. Tools - Jack and jack stands - Lug wrench - Screwdrivers (flathead and Phillips) - Brake spring tool (optional but helpful) - Pliers - Torque wrench - Ratchet and sockets

2. Materials - Replacement drum brake pads - Brake cleaner - Lubricant (high-temperature brake grease) - Safety goggles and gloves

Step 1 Preparation

Before you begin, ensure that you have a well-lit work area and that your car is parked on a flat surface. Put on safety goggles and gloves to protect yourself during the process.

Step 2 Lifting the Vehicle

Using a lug wrench, loosen the lug nuts on the rear wheels while the car is still on the ground. Next, lift the vehicle using a jack and securely place it on jack stands. Make sure it is stable before proceeding.

Step 3 Remove the Wheels

Once the vehicle is secure, completely remove the loosened lug nuts and take off the rear wheels. You will now have access to the drum brakes.

Look for any retaining screws holding the brake drum in place. If there are screws, use a screwdriver to remove them. If the drum is stuck due to corrosion or debris, you may need to gently tap around the drum with a hammer or use a brake drum puller to detach it.

Step 5 Inspect the Brake Components

Once the drum is removed, inspect the brake components, including the shoes, springs, and hardware. Check for excessive wear or damage. If any parts are worn, consider replacing them as well.

Step 6 Remove the Old Brake Pads

To remove the old brake pads (also known as brake shoes), start by taking out the return springs using pliers or a brake spring tool. Be cautious as the springs can fly off. Carefully remove the shoes from their pivot points. Take note of how the components are arranged to ease reassembly.

Step 7 Install the New Brake Pads

Compare the old brake shoes with the new ones to ensure they are the correct size. Install the new brake pads by reversing the removal process. Make sure to connect the springs and ensure all components are properly positioned. Apply a thin layer of high-temperature grease to the back of the pads to reduce noise and ensure smooth operation.

Step 8 Reattach the Brake Drum

Once the new brake shoes are securely in place, slide the drum back onto the wheel hub. Ensure it spins freely without excessive drag. If the drum feels tight, it might indicate that the shoes are adjusted too tightly. Adjust as necessary.

Step 9 Reinstall the Wheels

Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then use the lug wrench to tighten the nuts fully in a star pattern to ensure even tightening.

Step 10 Final Checks

Before taking the vehicle for a test drive, pump the brake pedal a few times to seat the brake shoes against the drum properly. Check the brake fluid level and make sure everything is in working order.

Conclusion

Replacing rear drum brake pads is a manageable task for those willing to learn. By following these steps and taking the necessary precautions, you can save money on labor costs and ensure your vehicle's braking system is in excellent condition. Always refer to your vehicle's service manual for any specific guidelines or torque specifications.
