Stuck rear calipers

I did my e-brakes this spring. I think I opened the bleed valve to make it
easier to turn the pistons. But if 15" channel locks won't budge the pistons
then they sound pretty bad.
PS - if you find the miracle solution for keeping the shaft from binding up,
let me know. Otherwise I see doing this every spring and I have better
things to do.

Searching the archives, I found little on this subject. Did a Google search
on the mother list as well.
I'm replacing rear rotors/pads since they are down to minimum. I'm changing
fluid and fixing stuck e-brake cable/rusted shaft
as well. (Just got done with suspension bushings).
Pistons will not retract at all, I don't have a special tool to fit into the
piston grooves. 15" Channel Lock is doing nothing.
Caliper rebuild time? I can take the calipers off and stick in the vise if
that will help. Do I need to crack bleeder valve to
relieve pressure, never had to do that so I suspect calipers are really
frozen. Need to pass inspection so I can get 20V
back on the road and tuck the 28 year old daily-driver 911 into garage for
If I have to rebuild calipers, do I need special tool to get them out?
