helping a buddy with a leaking rear caliper on a 914-4.

hard to tell exactly where its leaking from, but its definately the caliper (not the brake lines, etc).

i understand they commonly leak at some kind of seal on the adjustment mechanism.
is this true?

if so, is the seal available? if so, as detailed as possible a description of how to replace the seal would be hugely appreciated (assuming the caliper is off the car, we can get to that point!).

also, would it make sense to rebuild the entire caliper while we are there? if so, what does that exactly mean??? again, as much detail as possible would be hugely appreciated!!
