Is there any way you can slide something like a small putty knife (or 2) in the crack of the drum/rotor to force the shoes past the grove? If you are replacing the drum/rotor - you can get pretty rough with it May need a torch to cut it off, cut at bottom away from the caliper/ hydraulics. You may need a new set of brake springs.
Might be time for a brake shop with good tools.

Yes the adjuster looks either broke on installed backwards. If you pound it out it might free it up, but you may need some new parts that may get destroyed.

I don't understand the bolt trick, did you take any pictures?

Thanks, I'm still on the factory original rear rotors (2006) so probably going to need to do this soon.
