Drum Brake Replacement: Removing Assembly

Disc brakes have become a standard for many modern vehicles in both the front and rear axles. However, drum brakes are still common to find on the rear axle of many vehicles on the road today. It is still important for technicians to know how to properly and safely perform a drum brake job. In this video series, we will walk you through each step of quality a drum brake job.

In this week's episode, we take a look at inspecting, cleaning and lubricating the backing plate.

After removing the drum brake assembly, you will want to inspect the backing plate. Pay attention to the contact points between the brake shoes and the backing plate. If these contact points are not properly lubricated, or if the grease has worn off, the brake shoes will start to wear grooves in the backing plate. If the grooves are worn deep enough, the shoes can get caught in them. This can lead to brake noise or brake drag if left unattended. 

If the grooves aren't too deep, you can smooth them over by using a wire brush and a roloc disc. If the groove are too deep, there are two options for you: 

1.) Replace the backing plate

2.) Fill the groove with epoxy and smooth it over

After you inspect the backing plate, make sure to sure a high-temperature, synthetic lubricant on all contact points. 

Finally, clean the area around the anchoring pin with a wire brush. Now you can begin installing the brake shoe assembly.
