I am tempted to replace the cylinders and really want to.
The only problem is I am not sure if I can undo the 2 bolts that
hold the cylinder to the backing plate, and also undo
the hydraulic line nut that attaches to the cylinder.
If I knew these were not rusted on, I would change the
cylinders in a flash. Bleeding the system is no problem.
