Be sure it is sleeved with brass (White Hall does this not sure about the others), not stainless steel. SS will adventually wear away the rubber seals and it will leak

I have a M/C that was sleeved over 20 years ago w/stainless steel and have had no problems. I have to question that statement

Almost all C2/C3 brake calipers have been sleeved with SS over the years. Never heard of this wearing away the seals.
Dick,
Have heard this from several sources over the years. Don't know how many uses it takes for this to be a factor, may a mute point for most of us.
Talk to White Hall ( one of the inivators of sleeving MCs), they only sleeve MCs with brass for this reason. Doesn't seem to be a problem with calipers. Just saying if you are having it done, why not do it in brass.
Don't immediately assume that it needs to be sleeved. If it's only leaking at the seals, it may only need a little cleanup of the bore and a rebuild kit. Sleeving is a last resort. Ask whoever you give it to to only sleeve it if the bore is too eaten up for just a kit.

It may have been a problem with some of the early sleeve installers, but the ones that I have used for years are finished with what looks like a micro polish finish. I have installed quite a few over the last almost 30 years and have never had a problem. I have seen wear in the brass sleeved cylinders where the vehicle had quite a few miles on it.

The difference is that the pistons and seals in the calipers have very little travel. The pistons and seals in the master cylinder have a much greater travel.

Yes, if the bore is perfect sleeving is absolutely not necessary. If any imperfections in the bore can be cleaned up with crocus cloth it's OK for re-use, too. However, if the bore requires honing to clean it up, the best plan is to have it sleeved. I have found that honed master cylinders just won't perform properly.
