I recently replaced the drum brakes and shoes on my girlfriends Corolla. After the repair, the right rear side has an audible knocking/thumping sound that only happens when you press on the brake. You can also feel the thumping through the brake pedal.

Anyone run into this issue before? I pulled the drum off and everything looked fine. My only guess is that there is something going on with the adjuster. Either is not working correctly, or I didn't adjust it out enough?

B) probably have a retainer/spring that isn't on right or something is loose letting it rock inside the drum. Make sure you've properly set the adjustment to start with and that everything is locked in and drum is fully seated.


All of the springs are correctly installed and there is nothing loose. I set the initial adjustment by rotating the drum and adjusting until it felt like there was some resistance.
I can only guess that this is happening because the rear shoe is not fully contacting the drum, but if that was the case, it should have adjusted itself by now. Maybe the adjuster is not working correctly or stuck. This seems like a really common issue that should be on page1 of every repair manual.
