icole, how many holes are there in each rear caliper adapter bracket? Obviously, there should be four; two unthreaded holes, to bolt the bracket to the upright and two threaded holes, to bolt the caliper to the bracket. If one of these holes (or bolts) is missing, DON'T DRIVE THE CAR! Something is VERY wrong. If you don't know much about brakes, find someone who does, to help you.
