Not trying to say other ppl in here are wrong BUT....there is NOTHING wrong with separating the calipers. Have rebuilt quite a few z32 calipers and my brembo calipers on my old 350z. Worked great!!! Lots of ppl will say don't separate em but for those that have, I'm sure they can confirm also there isn't anything wrong with them, work perfectly fine after you put em back together. Just sayin...
