I took the car in for a basic brake fluid flush. During the work they determined that the rear calipers are knacked. This is not shocking news, I thought I night have a problem with the right rear since one of the pads was gone and the other was less than 1/2 consumed. The other side was even and at 1/2 use.
Since doing the brake job (new pads and rotors too) I've had squeel off the rear.. probably the right side so I'm pretty sure they are simply not trying to upsell me.
So.. all that background provided... should I have them attempt a rebuild or insiste they source some good used calipers? They are working up a quite for repacements (new) but I'm sure that's going to be into the thousands.. and by that point I might just by a full Big Red kit, right?
I do NOT know who to trust for used rear calipers. PM or post.. but I need to decided quickly which way to go. They are hemming and hawing about rebuilding them (hard to get parts blah blah blah). I suspect Sunset could source them for me and have them up here in a day or so.
I did run a search and got a lot of old threads but not the info I need.. in fact not much info at all.
Rebuilding - even worth attempting and what should I expect to pay for parts?
Good Used - what would those typically run?
New - that's GOTTA be expensive - should I just go big red and be done, sell off my new rotors and pads and front calipers?
TIA!

About the only thing I think that could be wrong is that one (or more) of the pistons is stuck, either the internal seal is knackered, or the outer boot is split and gummed up with brake dust. (or maybe the internal path is blocked with waxy stuff?)
Removal of the caliper is easy, and you can EASILY source new pistons and seals. I did this when I rebuilt mine after powdercoating.
Couple of hours labor (or DIY, it's not difficult, just a little messy)

Has all the Brembo parts you could possibly need. The StopTech pistons are a drop in for the Brembo ones...

Another thought is to try your local PEPboys.... yes I did suggest that... They list Porsche 993 calipers as a rebuilt unit on their "system", and I recall it was $200 last time I asked (a few months back)...

Hm.. I'm not sure there is a PepBoys up here in WA but I'll make some calls.. I'm sure they have another 'brand' name up here if not PepBoys themselves. And at under $200 each.. that's worth the saved hassle.
I've removed the calipers before on my 964 and the fronts on the 993 so I know it's not a big deal.
Thanks for the feedback guys!!! I was shocked that the calipers were under $500 each.. honest!

I would absolutely avoid replacing with new, but if you do get a new caliper, insist that YOU provide it yourself. Otherwise they'll ream you. IMHO they'd be unreasonable to insist you buy a new caliper from them when it can certainly be rebuilded.

As said rebuilding is easy and might be something simple but wont know until you get the pistons out.
I picked up a pair of mint 993 rear calipers on Ebay about 2 months ago. I paid $250 for them shipped with nearly new pads, sensors complete.

The big unknown for me is how much they will charge me to do the rebuild labor and weight that against my time and figure out if I want to hassle with it, then hav to rebleed (I guess I need to buy a proper power bleeder.... ).

I've had good luck with Mobile Brake Service in Seattle. They've rebuilt the calipers on my '87, and they've been excellent since then. I know of several other people who have dealt with them also, along with my mechanic. Might be worth a call.

Awesome Steve, thanks for that bit of info. I'll give them a ring and find out.
The shop wanted $600 to rebuild, $1000 to replace. I told them to hold off and I'll take the car home and think it out. Sounds like just doing the rebuild is the way to go. For the $200 or so in parts it's worth trying it myself or maybe having a shop do them. Bummer.. I was going to do a lapping day with my local club on Friday but not if the brakes are an issue..

:0 :0 :0 that sounds like fun. Maybe I'll order the parts (saving about 50% over what they want to charge me) and have them do the R&R.. will save me a couple hundred dollars and I can enjoy a day at work while they get covered with the brake fluid and other nonsense. Hm.. much to ponder.

Sometimes they can reasonable be rebuilt other times not.
a common issue is frozen pistons, if the bores aren't too deeply scared then new stock seals work fine, but if the bores are too badly damaged they must be bored to the next size or resleeved w/ s/s inserts.
another is that the area between the s/s pad holders and aluminum body corrodes and collects mung w/ makes it difficult to seat pads.
No matter, it won't hurt to take them apart and see what the damage is.
