caliper bolt torque

Thanks Cody for the diagram. I'm really surprised though. They're 14mm (thread) 10.9 class bolts. The recommended torque in my engineering tables show 133 ft/lbs. I tightened to 110 ft/lbs. with some threadlocker. I doubt the extra torque will make it move much if at all. It should hold for now, but I will probably re-torque to 148 once I get the right pads. I only replaced the rotors since Tirerack sent me the wrong pads (single-piston only).

Thanks to all.
