Caliper Rebuild
i will soon be replacing the pads, rotors and brakelines on the 911- even though the calipers are not leaking is best to rebuild them at the same time or wait until i see a problem later?
 thanks

Rebuild the calipers by draining remaining fluid, checking pistons and replacing the rubber seals. DO NOT however, repeat..DO NOT split the 2 halves.
regards, Steve

Michael, i'm not sure why Steve is parinoid about splitting the halves, but if you do, no worries. I've rebuilt hundreds of calipers, split them each time to clean everything, and installed new seals. Never had a problem.

The issue is the seals inside. Apparently, the seals are NLA. There was a thread regarding a fellow that recieved his Carrera calipers split, missing the seals, he couldn't locate them. It got pretty involved trying to find the correct size and material.

Also, the bolt looks like a torx, but apparently isn't and some have stripped them. I guess, if they aren't leaking (broke) why pull them apart? You can flush them out with clean fluid etc without dehalving.
regards, Steve

Trust me, do not split the calipers!! I have one new one, it was easier and less stressful than running out of brake...

i rebuilt my front out of need, and once apart there was no need to split the caliper. if you are rebuilding them under the "while you are in there" mantra, thats not a bad idea. but spliting them is a whole can of worms you may/will regret.

Neither seals between the halves nor bolts are available. There is no real reason to split them anyway, seals, bleeds and pistons are the main wear items

I would rebuild them. Not very difficult. I did the same about two months ago and very satisfied with results. My front dust boots were shredded and the pistons I found were not excactly at the 20 degree alignment. Had fun in the process. I just used a bike tire pump to pressure out the pistons. I also put on speed bleeders and they worked great. If you have the pressure or vacuum device, I hear they work great too.
Have fun!!

Seals
Try Cardone Industries for the seals. I bought a rear set of calipers for my 72T about 2 years back from Carquest and the caliper seals were a bit dry. I got the number for the company that rebuilds them from Carquest (Cardone) and spoke to their tech line. They sent me the new seals in a matter of days. I found once I put the caliper halves together they did show a bit of moisture between the halves for a short time frame. I waited about 24 hrs and tightened the halves once again and since all has been dry and problem free. Try looking for original rear calipers for a 72 if you want something a bit rare and expensive!
