Bud,
I have taken an old threaded brake line fitting and removed the brake line,
tapped the hole in the fitting for a grease nipple and harmlessly blooped
the frozen piston out of the corroded wheel cylinder using my grease gun.
The grease gun is probably good for several hundred or more psi and nothing
is recocheting off the rafters when it all comes loose - and it will come
loose!

Blue wrench time. I got some pretty badly frozen ones out with a propane
torch. They'll need resleeving, of course.
