The stuck piston may not come out with compressed air. If it doesn't, you're somewhat screwed.

The solution is to remove the stuck piston with the vehicle's hydraulic system. Get a suitable C-clamp and secure the GOOD piston. Be sure the stuck piston has a clear shot out of the bore. Return to the driver's seat and press the pedal about 10 times and the system pressure should dislodge the stuck piston.

Of course, now you've got the distinct pleasure of trying to plug the bore so that you can remove the opposite piston with compressed air. I used a piece of rubber held in place with a piece of wood. A second piece of wood is used as a backing plate behind the caliper and two C-Clamps keep the two pieces of wood secured to each other.

This is not one of those jobs that I care to repeat. I'll give them the $150 for the pair to avoid all this BS. And, I need to do the exact same thing on the SDL front calipers. Outboard LF piston is frozen solid.
