How to Remove a Drum Brake Backing Plate A Step-by-Step Guide

Removing a drum brake backing plate may seem daunting, especially for those who are not experienced with automotive repair. However, with the right tools and instructions, anyone can accomplish this task safely and efficiently. In this guide, we will walk you through the essential steps to remove a drum brake backing plate from a vehicle.

Tools and Materials Needed

Before you begin, gather the following tools and materials - Jack and jack stands - Lug wrench - Brake cleaner - Socket set - Wrench set - Screwdrivers (flathead and Phillips) - Pliers - Hammer - Replacement backing plate (if necessary)

Step 1 Prepare Your Vehicle

Start by ensuring your vehicle is parked on a level surface. Engage the parking brake and place wheel chocks behind the front wheels (if working on the rear brakes).

Using the lug wrench, loosen the lug nuts on the wheel where you will be removing the brake backing plate. Do not completely remove them yet.

Step 2 Lift the Vehicle

Using the jack, lift the vehicle and securely place it on jack stands. Ensure that the vehicle is stable before proceeding. Once it is secure, complete the removal of the lug nuts and take off the wheel.

Next, you will need to remove the brake drum. The drum may be secured with screws or held in place by rust. If there are screws, use the appropriate screwdriver to remove them. If the drum is stuck, gently tap it with a hammer to loosen it. Once loose, slide the drum off to expose the braking components.

Step 4 Disconnect the Brake Components

Before you can remove the backing plate, you need to detach various components. Begin by removing the brake shoes, which may involve taking off springs and retaining clips. Use pliers and screwdrivers as needed to free the shoes from their mounting points.

After removing the shoes, disconnect the wheel cylinder by unscrewing the brake lines from it. Be cautious, as brake fluid will leak from the lines; have a rag or container handy to catch any spills.

Step 5 Remove the Backing Plate

With all brake components detached, locate the bolts securing the backing plate to the axle housing. Using the socket set, unscrew these bolts and carefully remove the backing plate. If the backing plate shows signs of corrosion or damage, consider replacing it with a new one.

Step 6 Clean and Inspect

After removal, take the opportunity to clean the area and inspect the brake components for any signs of wear. Use brake cleaner and a cloth to wipe down the surfaces. Replace any worn components as necessary.

Step 7 Reassemble or Install New Components

If you are installing a new backing plate, position it where the old one was and reinsert the bolts to secure it. Follow the reverse order of steps to reassemble the brake components, ensuring everything is tightened and functioning correctly.

Conclusion

While removing a drum brake backing plate requires basic mechanical skills and the right tools, following these steps will make the process easier. Always prioritize safety, and if you are unsure about any step, consult a professional mechanic. With patience and careful execution, you can complete this repair and gain confidence in your automotive abilities.
