Charlie, I had the exact SAME experience with a caliper I bought from AutoZoo! Bought it, took it home, didn't get around to installing it right away... by the time I did I found to my dismay that the caliper rubbed against the disk! The difference was, in my case it was too late to return it, so I missed out on all the interaction with the non-helpful staff. I looked at that piece of junk and thought, "Well, I could spend an hour filing this thing down, or I could go to the place that specializes in German car parts... get in the car." Ended up buying a whole 'nother caliper, and the useless one still sits under the workbench in the garage for the day when somebody needs a core.
