I am wondering how much material you can safely remove from a wheel or master cylinder to get rid of pits and still have the cups not leak fluid past them? I have adjustable reamers and some fairly well pitted cylinders. For instance, a 1 1/8" cylinder comes in at 1.125. Can you take it out to 1.140 and still be safe?
