I recently had a stuck rear wagon caliper that wore down to the metal. The damn rebuild was less than a year old! I don't like ordering calipers online because of the shipping on the cores so I went to my local NAPA. They couldn't get a wagon caliper. Since I needed the car (and I'm a redneck mechanic), I ordered the sedan caliper and installed it, knowing it was not correct.

The car brakes fine and there is no pulling or unusual behaviour. As was said, the pads are the same as the wagon. I took a chance and so far it is working out.

Your results may vary.
