Just a quick note. I had the same problem with my brake cylinders and the
careful use of heat did not move them, nor did compressed air. I read once
that hydraulic pressure from a grease gun could move them but just try and
get a fitting!!!! I finally took a bolt that fit the thread size and
carefully drilled it down the center and then drilled the head end to accept
a tap the size of a grease fitting. This method moved every cylinder, no
matter how badly stuck, within seconds. It takes a little time to make this
"tool" but it was well worth the time.
