I have to disagree. The key is to be able to distinguish between a
"rebuildable" and one that isn't. If it is OK the service life is as
good as a new one if the repair technique is correct. Clutch slave
cylinders and master cylinders wear a LOT more than brake ones due to
the greater frequency of use and the full length stroke on every
application so they need replacement more frequently - especially the
aluminum slave since it runs in a "dirty" environment.
Cast iron cylinders that are resleeved with brass are actually "better
than new" since they barely wear and don't corrode. They can then be
rebuilt practically indefinitely. They make sleeving a better deal than
replacing with new ones. Jarl
