My brakes have been making this squealing noise for a few weeks now. I know its not the hub bearings. Its only during light braking like coming up to a stop sign or whatever.

I pulled off the pads and tried that anti squeak stuff on the back of the pads. No dice. Any suggestions. Pads and rotors have less than 2k on them? Cheap brakes? That was my best guess. I've read it could be the abs bracket rubbing but I don't remember the source of that info. Any ideas?
