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?
