How to Change Drum Brake Pads A Step-by-Step Guide

Changing drum brake pads is a crucial maintenance task that every vehicle owner should learn how to do. Drum brakes are commonly found in older vehicles and on the rear wheels of many modern vehicles. While the process may seem daunting at first, with the right tools and a little patience, you can complete this task efficiently. Below is a comprehensive guide on how to change drum brake pads.

Tools and Materials Needed

Before you start, ensure you have all the necessary tools and materials

- Jack and jack stands - Lug wrench - Brake drum puller (if needed) - Screwdriver - Pliers - Brake cleaner - New brake pads - Spring tool (if required) - Safety goggles and gloves

Step 1 Safety First

Begin by ensuring safety. Park your vehicle on a flat surface, engage the parking brake, and wear safety goggles and gloves to protect yourself from debris and dust.

Step 2 Prepare the Vehicle

Loosen the lug nuts of the rear wheels slightly but do not remove them completely. Use a lug wrench for this step. Then, use a jack to raise the car, and place it securely on jack stands. Once the car is stable, remove the loosened lug nuts and take off the wheel to access the brakes.

In many cases, the drum can be easily removed by pulling it off. However, if the drum is stuck, you may need to use a brake drum puller. If you don’t have one, you can gently tap around the edges of the drum with a hammer to loosen it. Once the drum is off, inspect it for any significant wear or damage. If the drum looks worn, consider having it machined or replaced.

Step 4 Inspect Brake Components

With the drum removed, take a close look at the entire assembly. Check for the condition of the brake shoes, springs, and hardware. Look for signs of excessive wear, contamination, or damage. If any parts appear to be in poor condition, consider replacing them before proceeding.

Step 5 Remove Old Brake Shoes

Next, you will need to take out the old brake shoes. Start by removing the springs holding the shoes in place using a screwdriver for leverage and pliers if needed. Be careful of the tension on the springs, as they can snap back. Once the springs are removed and the shoes are free, take out the old brake shoes.

Step 6 Install New Brake Shoes

Before installing the new brake shoes, clean the backing plate and other components with brake cleaner. This removes any dust, grime, or grease that could impair braking effectiveness. Then, install the new brake shoes in the same position as the old ones, ensuring that any features align correctly.

Step 7 Reassemble the Brake Assembly

With the new shoes in place, you can begin reattaching the springs and any other hardware. Use the spring tool to stretch the springs back into place if needed. Ensure everything is secure and properly positioned.

Step 8 Reattach the Brake Drum

Once the brake shoes are installed and the assembly is complete, replace the brake drum. If the drum is tight, gently tap it into place with a rubber mallet. Ensure that the drum moves freely once it is installed.

Step 9 Reattach the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground and then use the lug wrench to tighten the lug nuts in a cross pattern, ensuring even pressure.

Step 10 Test the Brakes

Before taking your vehicle back on the road, pump the brakes several times to ensure the brake shoes settle properly against the drum. This step is crucial as it builds up brake pressure. Once you've done this, perform a short test drive in a controlled area to ensure everything is functioning correctly.

Conclusion

Changing drum brake pads is a manageable task that can save you money on a mechanic’s bill, provided you take the time to do it right. Regular maintenance of your brake system is essential for both safety and efficient performance. Always consult your vehicle's service manual for specific instructions related to your make and model, and don’t hesitate to seek professional help if you're unsure about any step in the process.
