Don't over-tighten the front caliper bolts. I broke one off on our GXP when we had it, and there was only a handful left on dealer's shelves. My dealer had to get one from NJ. And that was 6 or 7 years ago...

I used the specs that were listed here which were like 100+ ft/lbs and that's what busted that bolt. I've always gotten them good and tight with a standard ratchet, and never had a problem with them coming loose again. YMMV.

Also, with caliper pins it's essential to lube the part of them that the caliper slides on with a good high temp silicone lubricant, such as Sil-Glyde.
This will help ensure that the calipers slide freely, as they're designed to do.
Napa has it, as does Amazon and other parts stores http://www.napaonline.com/p/BK_7651351

That applies to any "floating" caliper. Not just here.
