Drum brakes making noise
 

A few months ago I got my drums changed out because they were caked up with rust, but the day after my mechanic put the new drums in I noticed when I hit the brakes it would make a crunching noise. Like a disgusting crunching and grinding of metal being chewed, then right before I stopped would give out a nice squeal, kinda like a bus. I told my mechanic about it and he said he'd look at it, but it's been a while now and they're still crunching, or more so just squeaking by now.
At first I thought it was because the brakes were new, but I've been using them for a pretty long time now and they still crunch and squeal, but they don't seem to be damaged or anything.

Is this a problem I should really be concerned about, and can it lead to even more damage?

check to make sure the backing plate isnt bent in the back .. It could be hitting the drum when it spins...

I figured it could be something interfering and scratching, or maybe a bad alignment.
