I have one rear brake piston that's good and seized - she don't want to free up for love or money.
It's seized in the fully recessed position and refuses to budge - whether worked through fully bled master cylinder pressure or disassembled wrench coaxing.
Any ideas?

Compressed air. But be careful. That cyclinder will come out of their like a bullit. Always use a rag over it and point away. Doesn't take much air to do the trick. Be careful.

Sadly - no tengo air in my feeble shop. I will shortly attempt the BFW [monkeywrench + pipe extender] approach and see how she goes. I expect it will mangle the small exposed rim a bit but, as long as that's filed down and fairly flat against the pads, I guess it shouldn't hose me.

Rumor has it that the somewhat desperate use a grease gun through the bleeder valve after blocking the intake.
And that the truly desperate in fix-it-or-kill-it mode fill with water, close the air valve, block the intake, and put in freezer. Either piston comes out or caliper bursts.
Has it been soaked constantly with PBBlaster or Kroil for a few days, and maybe a week, before attempting removal with line fluid pressure or air pressure, or even the grease gun method?
Good Luck!

Patton - now that's just the sort of borderline-reckless, threadin'-the-needle type of advice a feller like me relishes.
I'm down to the house over the breadth of my admittedly brief wrenching/fixing career, with many a probably fixable electrical & mechanical component forced the way of the dodo by my hand...but I sure have learned a metric ton.
Dealer - hit me.
