i personally think Chris is being overly cautious about this but it's your rig, you make the call. i would at least pull it apart and evaluate it first.
if it's just a leaking seal, re-seal it.
it the pistons are pitted, it might be worth the cost for a caliper.
i for one, don't think the rebuild it much of an issue, but i do this crap for a living too.
there really isnt much to it
just put it back the way it comes apart, and make sure the seals face the right direction.
and use plenty of brake fluid to prelube the seals. makes assembly easier.
