I too have rebuilt many a slave and master cylinder in my youth.  I quit
years ago because they never lasted more that a few months or few
thousand miles.  The bore is very precise, and usually by the time the
seals leak the piston has distorted the bore enough to make rebuilds
short-lived, and if you hone the scoring/pitting out it usually gets too
big.  I don't bother with this any more.  These components are usually
not that expensive, and in the case where they are I send them out to be
re-sleeved by White Post Restorations.  That is the only way to get a
rebuild to last.

Start saving your pennies now for the new one, and the master too!
