This is the 911. The previous time I rebuilt these calipers, I had this compressor and don't recall having a problem. I'll try again. If no luck, I might be able to cut/mutilate off the seal and expose enough piston to grab.

I thought that, worst case, I connect the calipers to the hard line, with no rotor or pads, fill fluid and bleed the brakes, and use the pedal to press out the piston. Being careful not to push the pedal too far. Would that work? Sounds like a big pita and waste of fluid.
