Wierd Brake Sound

Took the SC out this past weekend, and the brakes started to make a funny sound, kind of like the pads were worn out. But I just got new pads a few weeks ago. Wierd. I think I am going to take to the shop this week to have it check out. Sucks.

I took the wheel off and looked at the brakes... to be honest, I have no idea what I was looking for. I know what the parts are, what they do... but have no idea how to trouble shoot any of that.
