How to Replace Rear Drum Brake Pads

Replacing rear drum brake pads is a vital maintenance task that contributes to your vehicle's overall safety and performance. Drum brakes operate differently from disc brakes, and understanding their structure will make the replacement process more straightforward. Here’s a detailed guide to help you replace rear drum brake pads effectively.

Tools and Materials Needed

Before you begin, gather the following tools and materials

1. Tools - Jack and jack stands - Lug wrench - Brake cleaner - Tire iron - Screwdrivers (flathead and Phillips) - Pliers - Socket set - Torque wrench

2. Materials - New brake pads - Brake spring tool (optional but helpful) - Brake lubricant (high-temperature) - Clean rags

Step-by-Step Guide

1. Prepare Your Vehicle

Start by parking your vehicle on a flat surface and engaging the parking brake. Loosen the lug nuts of the rear wheels slightly without removing them. Then, using a jack, lift the rear of the vehicle and secure it with jack stands to ensure stability. Remove the rear wheels completely.

2. Remove the Brake Drum

Locate the drum brake assembly behind the wheel. You may find dust covers that need to be removed first. Once exposed, look for the retaining screws holding the drum in place. If the drum is stuck due to rust or debris, gently tap it with a hammer to loosen it. Once free, carefully slide it off the hub.

3. Inspect Brake Components

Once the drum is removed, take a moment to inspect the entire brake assembly. Look for wear signs on the brake shoes, springs, and other components. If any parts are damaged or excessively worn, they should be replaced along with the pads.

4. Remove Old Brake Pads

To remove the old brake pads, take note of their arrangement and how they are attached. Generally, they are held in place by springs and clips. Use pliers or a brake spring tool to detach them carefully. Be mindful of any other components that may come loose during disassembly.

5. Clean the Brake Assembly

Using brake cleaner, generously spray the drum brake components to remove dust and debris. This is crucial because brake dust can diminish performance and lead to noise issues if not cleaned properly. Wipe everything down with a clean rag, allowing it to dry.

6. Install New Brake Pads

Position the new brake pads in the same arrangement as the old ones. Ensure they are securely installed and seated properly against the brake backing plate. Pay attention to the alignment of the springs as well; this step is essential for proper function.

7. Reassemble the Brake Drum

Once the new brake pads are in place, carefully slide the drum back over the brake assembly. Ensure it fits snugly onto the hub without any obstructions. If applicable, replace the retaining screws to secure the drum.

8. Reinstall Wheels and Lower Vehicle

With the drum in place, it’s time to reinstall the rear wheels. Make sure to tighten the lug nuts by hand before lowering the vehicle. Once lowered to the ground, use your torque wrench to tighten the lug nuts to the manufacturer’s recommended specification.

9. Test the Brakes

Before hitting the road, pump the brake pedal several times to ensure the brake pads seat correctly against the drum. Check for any unusual noises or issues. It’s also good practice to do a quick test drive in a safe area to ensure everything is functioning correctly.

Conclusion

Replacing rear drum brake pads can seem daunting, but with the right tools and a clear understanding of the steps involved, it's a task that can be completed successfully. Regular brake maintenance not only enhances your vehicle's safety but also improves performance and extends the lifespan of your brake components. Always consult your vehicle’s manual for specifics, and consider seeking professional advice if you are unsure about any part of the process. Happy driving!
