Default Caliper bolt broken/frozen

Bottom bolt for the caliper broke. Half of it came out half of it is still in the bracket. Any suggestions on how to get it out?

Couple more pics. Did the pass side brakes really easily.

In those situations, I use an easy out.

I welded 2 heated wide band O2 sensors on my truck. I also "tried" to tint my driver'* window and vent window and it doesn't look good.

I could try and use one, but I don't know if it will have any affect. It'* worth a shot.

Grab a pair of brand new vise grips. Clamp onto the bolt. Heat the part the bolt is threaded into with a plumbers torch and try to rotate it out.

That was the first thing I tired. Used my acetylene torch. I had that thing red hot too.

Looks like you may have to drill it out now.

My apologies for asking what is probably a stupid question, but did you heat the bolt or the bracket?

First I heated the bolt, try to remove it and nothing. Heated just the bracket away from the bolt and still could not remove. Tried an easy out today and it snapped the bit.

What if I welded a nut on the end of this bolt and then tried to turn it out with a wrench?

Thoughts?

Weld a nut on the bolt, let it cool, and heat the bracket (not the bolt). When the bracket is hot, spray some WD-40 or PB Blaster on the bolt and try turning it out. The spray will cool the bolt a little. You want the bracket hot and the bolt cool. If that doesn't work, you may have to drill it out

By the way, you can get a new caliper bracket off rockauto for around $12.
