Clunking in rear

[COMETKID]

I have noticed that my drum brakes are making clunking noises whenever I'm breaking or just driving in general. It's not constant either one day it will happen and the next it will happen for 20 minutes straight. I'm not sure what the problem is exactly but I know that when I break I feel the clunking travel to my brake pedal. Does anyone know what is going on?

Yeah, I know what's going on. Shit's broke.

Start taking wheels and drums off and looking for something that doesn't look right. Take and post pics if you aren't sure if it looks wrong or not.
