I tried heat first, Carful not to cook any brake fluid/lines in the process. No luck. Going for the acetone concoction next. Thanks for the imput.

you say it came part way out then locked up.????
I wonder if it is cross threaded?
If you can turn it in- try working it in and out with the acetone -ATF concoction I mentioned. When you use it let set for half hour or so after you put it on the bolt before you try to get it out.

It did create a gap behind the caliper before it bound so I poured the special sauce as close to the base of the bolt that I could. It didn’t feel crossed, more of a galled feeling.

I don't know how much play there is between the bolt and the thru-hole on the caliper, but what you're describing seems to me like the bolt is binding up on the caliper itself, not the threaded parts. Try running the bottom bolt back in and snug it up. This will help keep the caliper down while you're working the other bolt out.

The caliper will slide ( a little) on the bolt shaft. I have about 3/4 in. of thread still in the hub. The bolt I got out looks to have been coated in something. The threadd are not clean but it came out nice.

Unfortunately, I think the damage is done. From what I've experienced, if the bolt starts coming out and then gets jammed up. Part of the aluminum threads have stripped and are attached to the bolt. As the bolt is coming out, those stripped threads are now binding against good threads. I hope I'm wrong

That's what I thought until I put a magnet on it and it stuck. They both look the same. I was wondering if low and slow torque or high impact would lessen the chances of it breaking.

Ah yes, that's aluminum. I forgot about that. Aluminum and steel don't like each other. There is bad chemistry between them.
