My years of experience, (and I am pretty stupid) is to heat the outside of
the cylinder with a torch (lightly) and bang the sucker until the piston
comes out. I soft wire brush on a wheel the piston and external parts, and
use an emory cloth to polish the inside. Change the rubbers from a rebuild
kit, apply the red grease made by Girling to the area of travel of the
piston, and I have never had a problem. (If the cylinder is pitted so bad
that you can't remove it with the emery cloth, get a new cylinder .
