Be very careful heating with a torch. If the caliper gets hot enough it may explode.
Spray the threaded area with penetrating oil and give it ample time to work.
You might tap the end of the bolt sharply a few times.
Sometimes this will loosen them up a bit and make removal easier.
I have used a very small pipe wrench with success in the past.
Or you may just have to clamp the vise grips onto the bolt as tightly as possible and give it another go.
If you can grind or file a flat spot on two sides of the bolt head it will help you get a better grip too.
