Removing caliper on W126

[GTStinger]

Trying to remove the calipers as part of rebuilding the front of my '83 300 SD. Everything I've seen here says you take off the two innermost bolts and presto. I've done that, but the caliper appears to be engaged to the rotor. I can rotate the caliper a half inch or so along with the rotor, but I can't pull it outward from the center. Is there another bolt I must remove or a release somewhere?

I know I got both bolts secureing the caliper to the wheel and not the ones holding the two halves of the caliper together.

Wish the factory manual wasn't so skimpy on the calipers. Guess they figured anyone buying the manual would already be experienced with brakes.
