Hi Bill,
How's your heater blower working?
About the pistons... I just stuck a board down between the pistons and cranked up the compressor. Jim's still didn't move. We gave the pistons a little persuasion (rotation) with some vice-grips... reapplied the psi and out they came.
I like your idea of trying to do them on the car... next time I do my calipers (I hope that's several years from now!!) I'm gonna get the pistons 1/2 of the way out before removing the calipers from the car. A little wood between piston and rotor should prevent any damage.
I don't think you can get the pistons all the way out with the caliper still mounted due to the thickness of the rotors. Also, I wouldn't want to risk spraying brake fluid all over my wife's car!!
However, your idea is a great way to make the final piston removal step much easier.
