If its one or two pads out of the four at the rear its probably just the pistons getting stuck in the calipers and holding the pad on the rotor. Get a rebuild kit from race brakes and pull them apart, clean them up and assemble with the new seals in the kit. Might as well do both calipers while you're at it. When i did mine i gently cleaned up any scoring on the pistons with 1200 grade wet and dry sandpaper.
