I too had stuck cylinders after 18 years of storage. After trying the soaking
in liquid wrench for about 2 months, 125# air pressure for some period of
time, the grease gun attached to an old brake line, I just drilled a 3/8"
hole in the steel piston cup, used a "large" screw extractor and wrench and it
came right out. You can purchase new steel piston ends without having to buy
the whole cylinder which is very expensive for a TD since you need 2 per
wheel.
I did have a couple of spare cylinders to try my approach on.
