Hi Ryan,
DS2500 are terribly dusty, not my favourite choice but a bit late now.
1. Re-do the bedding process several times until it clears off any vibrations, providing that all bolts and nuts are properly done, see here: http://torqen.uk/docs/TORQEN-brake-bedding-web.pdf
2. Apply some copper grease on the back of the pads. Ensure caliper is spotlessly clean with proper free movement of pistons, if possible fit new hardware, eg StopTech pads come with new hardware kits. You can also chamfer the edge of the pads if that doesn't work.
