How to Replace Rear Drum Brake Pads

Replacing rear drum brake pads is an essential maintenance task that ensures your vehicle operates safely and efficiently. This process may seem daunting, but with the right tools, materials, and instructions, you can perform this task yourself. Here’s a step-by-step guide to help you through the process of replacing rear drum brake pads.

Tools and Materials Needed

1. New brake pads 2. Brake drum puller (if needed) 3. Socket set and wrenches 4. Screwdrivers (flat and Phillips) 5. C-clamp or brake piston tool 6. Brake cleaner 7. Torque wrench 8. Rags and gloves 9. Safety glasses 10. Jack and jack stands

Step 1 Preparation

Before you begin, gather all the necessary tools and materials. Make sure your vehicle is parked on a level surface and engage the parking brake. Wear safety glasses and gloves to protect yourself during the process.

Step 2 Remove the Wheel

Using a lug wrench, loosen the lug nuts on the rear wheel where you’ll be replacing the brake pads. Then, using a jack, lift the vehicle and secure it with jack stands. Once the vehicle is stable, fully remove the lug nuts and take off the wheel.

Step 3 Access the Brake Assembly

After removing the wheel, you’ll have access to the brake drum. If your vehicle has drum brakes, you may need to remove the drum to access the pads. Depending on the model, the drum might slide off easily, but in some cases, you might need a brake drum puller if the drum is stuck due to rust or wear.

Step 4 Inspect the Components

Before replacing the brake pads, inspect the condition of the brake drum and other components like the brake shoes, springs, and hardware. Look for any signs of wear or damage. If the drum is worn beyond the manufacturer’s specifications, it may need to be resurfaced or replaced.

Once you have access to the brake shoes and springs, note their configuration for reassembly. Use a screwdriver to carefully detach the springs from the brake shoes, and then remove the shoes themselves.

Step 6 Install New Brake Pads

Take your new brake pads and match them to the configuration you observed when removing the old ones. Install the new brake shoes by positioning them in place and securing them with the springs. Make sure the shoes move freely and are aligned correctly.

Step 7 Reassemble the Brake Drum

After installing the new pads, it’s time to reassemble the brake drum. If you removed the drum, slide it back onto the wheel hub, ensuring it fits snugly. Check the operation of the brake assembly by manually spinning the drum to ensure it’s not bound up.

Step 8 Reattach the Wheel

With the drum back in place, it’s time to reattach the wheel. Place the wheel onto the hub, and hand-tighten the lug nuts. After the lug nuts are on, lower the vehicle back to the ground using the jack, and then use a torque wrench to tighten the lug nuts to the manufacturer's specifications.

Step 9 Test the Brakes

Before driving, it’s crucial to test the brakes. Firmly press the brake pedal several times to seat the new pads against the drum. This action ensures that the brake pads are properly aligned and functioning.

Step 10 Final Check

After the test, take a short drive in a safe area to confirm that the brakes are working effectively. Listen for any unusual noises or pulsations. If everything feels and sounds normal, you’ve successfully replaced your rear drum brake pads!

Conclusion

Replacing rear drum brake pads may seem intimidating, but with some patience and the proper tools, it can be accomplished by anyone willing to learn. Regular maintenance not only enhances the safety of your vehicle but also extends the lifespan of the braking system. Remember, if at any point you feel uncertain, consult a professional mechanic for assistance. Safe driving!
