Re: Torque wrenches and caliper bolts
A thought, was there anti seize on the threads? One must remember, that unless the threads were lubricated from the factory or the torque spec is noted as "oiled" you must reduce the torque by approximately 25% to get the same clamping force as a "dry" fastener. By applying the same torque to a lubricated fastener (such as anti seize), you are creating a much higher clamping force, and thus you are more apt to stretch the bolt to yield.
As far as the torque wrench not clicking, I have a newer craftsman torque wrench that seems fine above 100ft lbs or so, but below that it seems to do what you are speaking of. I don't trust it very much, and tend to use my older wrench instead.
