Talking about a 77 Corvette.

The caliper is mounted too close to the rotor to the point of rubbing the back side of it. I can't quiet figure out what's off. Do I need a thinner rotor or is the wrong type of caliper being used? Check our this image:

Here is what the caliper bracket looks like:

Look at the grooves on the back of the rotor the rubbing has caused:

The pads seem fine, which I don't think should make a difference anyway.

Everything appears to be nice and tight, it's as if the part of the caliper that goes between the bracket and the rotor is too thick. What am I missing here?

According to this Russ is right.

This is interesting. However, looking at the grooves on the rotor from rubbing on the caliper, I would think the issue is with the thickness more so than the diameter of the rotor. What's the difference between nominal thickness and minimal thickness?
