caliper help

yesterday i heard a pop and then a ping… i think the right rear caliper went cause it seems like its been sticking lately. anyways i lost all my brakes… didnt see any fluid though… gonna crawl around under it today. anyways how do i go about rebuilding a caliper or would i just be better off buying a whole new one?

buy new

i think Brian can get a discount from a Ford dealership around his place

dude autozone wants 140 for a new rear caliper… lol wonder what a ford dealer wants
