Nope, that looks like a typical GM brake assembly with a pair of bolt/slider pins with a allen head that is unscrewed. This one has one bolt, which is pretty small (has 12mm hex head) and there is some sort of pin in the front position where I would expect a bolt. All the instructions (I have the factory W body manuals) say is to remove it to take the caliper pad frame off. I am trying to remove the pin gracefully rather than with a hammer and chisel, and assumed that I could hardly be the first person with a W body GM rear brake caliper pad frame that needed to come off. I am trying to disassemble everything on each side to clean, lube, replace any warn parts, etc. While I replace the strut. Even the factory exploded diagram of the rear assembly is small and vague. It would take someone with experience with a 95-96 regal to have worked on these brakes/calipers I suspect, to know how the thing disassembles cleanly.

Can you upload a pic for me to look at?

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.

I am glad you got it taken care of. I believe I can picture what you now described. However, a picture may help others in the future. If you can, it would be great.
