I can later, but I also got it off. Just had to tap the caliper pad frame with a small brass hammer, it was stuck on the pin. On these assemblies, there is one bolt (small) and the brunt of the force is taken by sliding over a fixed pin in the caliper assembly. It was stuck on the pin, and I thought the pin came out, which it doesn't, rather it slides in and out (in theory) on the pin in order to center the pads on the rotor. Needless to say, the inside rotor face is screwed up, and the pads are worn crooked. I noticed that the small bolt is bent, and I think that lets the frame ride a bit crooked, which caused the uneven wear.
Thanks for your responses. This is my first time with the GM W-body rear disc brake/integral parking brake assembly that is built like this. It doesn't seem like a very strong assembly, no doubt this would only work on the back where the braking forces aren't nearly as high as the front.
