My rear passenger caliper has some rust pits around the piston. Next time you are back there retract you piston manualy out an inch or less and peel back the rubber boot and look for pitting. Just something to look into along with the other suggestions.
I still have that problem, I don't know if it is possible to purchase a piston replacement.
