Air tool won't even break loose the two smaller bolts? These two bolts should have a rubber type grommet after the head.

Are you working on the caliper retaining bolts or the caliper bracket bolts? I am sure the caliper bracket bolts have threadlocker on them, and the caliper bolts may also have it on them, some heat on the bolts will loosen the locking compound. Apply the heat to the area where the bolt threads into the bracket or spindle. Only takes about 500 degrees to get threadlocker to let go, so you do not need to heat to glowing red, heat a little, try to remove and so on.
