I recommend sleeving the cylinders if they're pitted. There is some
debate as to what is best (stainless or brass) because of a galvanic
electrical reaction between ss and aluminum. I have been told that the
danger is minimal. My master is sleeved with ss and I'm quite happy
with it, so far. My wheel cylinders were slightly pitted and I scuffed
them up with a brake hone using a hand drill. Apparently one of thm
was pitted badly and has now failed so I'll probably end up sleeving
them. If you're interested I can refer you to someone who does
sleeving at a very reasonable price.
