Look at your T50 socket and make sure it's still in good condition. If not, get a new one and while you're at it, get a small tube of valve grinding/lapping compound. Permatex makes it . Put the grinding compound in the T50 hole in the caliper bolt. Insert the socket. You'll be surprised how tight it grips. Works on allen headed fastners as well. Used to have to do it all the time on corroded allen headed bolts on boats.

I had the exact same problem on mine. The Star was no longer a star on my bolt it was totally round. I couldn't get it with a pipe wrench or vice grips.
What I had to do was to cut my caliper with a cut off tool. In other words break that corner of my caliper off in order to remove the bolt. So now I need to buy another caliper. If you need a picture of the caliper I can probably take one tomorrow for you.

The same thing happened on my 1984 Fiero - on both sides. I got these things from Sears. They are hexagonal on the outside, and have several sharp edges on the inside. There are several different sizes in a kit. Sometimes you have to tap them on the OD of the bolt you're trying to take off. Then get a big breaker bar and a socket that fits and break the bolt loose. Copious amounts of PB Blaster help also. Then when installing a new bolt, use anti-sieze. Some of it will probably wash out if you drive in the rain, but hopefuly it will help when you need to take your caliper off the next time.
Tight tight vise grip should remove,I would use large vise grips and BFH to knock loose then reapply vise grip to remove. next!! last resort,,.hope you can remove with out resort to this..Cheapest method is to drill thru bolt head,if possible,, yes it will mess up the caliper but you will still be able to use it,,your drill bit should be same size as bolt or slightly bigger..then reverse drill and drill into bolt with smaller drill to help loosen.go from there.also work around bolt head with punch to loosen first you might get lucky,these are normally tight,,,bolts in rear a female dog to get to with drill and bit,unless you remove from car..if job turns into real bear ,, putting ice bag on caliper will give small assist in removal(don,t laugh) it works, the caliper will cool & retract before the bolt..my centavo & hryinias worth

Had the same thing happen to me recently on my 86GT. Bottom T50, right rear caliper. Tried the welding idea but did not work. Guess is was the difference in the metals (T-50 tool and caliper hold down bolt). Tried an easier method, removed the rubber booth on the bolt, used a small pipe wrench. I had also tried using a vice grip but could not get enough bit. The small pipe wrench worked for me.
