[s-cars] brake upgrade w/used calipers?

[Kenneth Keith]

Hi,

I finally have some aftermarket wheels on my 200q20v with some decent
brake clearance, and it's time to get some brakes that work better
than the G60's.  I planned to do the relatively low buck setup with
the A8L rotors, RS2 brackets, and either 993tt or 996 calipers.

I read some of this months S-car list archives about big brakes, and I
know those/you guys are all over G60 brake upgrades, so I'm posting
there too.

I'm wondering how reasonable or not it is to buy some used calipers
and expect to bolt them on and use them without having to rebuild or
recondition them, thereby negating the cost savings of going used in
the first place.  I could ask the seller of the used calipers, but he
wouldn't be impartial. =)

I can apparently get new 993tt calipers for $600/pair from Crescent
Porsche, or used 996 non-turbo calipers for $400 from that well known
Porsche dismantler on the west coast.  I think I prefer black, if that
matters.  I have the RS2 brackets already, and can get the rotors for
$85 each.  I haven't priced the bolts, lines, pads, and other
ancillary stuff yet.

I know people have used used calipers before successfully, but perhaps
someone has a story about buying used calipers and it not going
smoothly?  At this level, would it be foolish to try to save some cash
by going used?  Is there a third option that is cost competitive, like
rebuilding some used calipers myself?

Cheers,

Ken
