Foot lbs for which bolt?
SOURCE: 93 plymouth voyager
Easy peasy, 12 inch-lbs is 1 ft-lb, sooo! 72 inch lbs is 6 ft-lbs and 41 inch-lbs is about 3.5 ft-lbs.
Basically 72 is just hand tight and 41 is snug ;-)
SOURCE: for tightening head bolts on my car it says to
Because, by the time you twist that bolt to let's say, 65ft.lbs, it could snap.
The manufacturer of that bolt knows that if the bolt is torqued, (Stretched) to a certain torque value, and is turned a certain amount of degrees, the proper torque value will be reached, and still stay within the guidelines of the tensile strength of the bolt.
Torque is set to Bolt Stretch. How far the bolt will stretch in a given torque value, and not exceed it's tensile strength. The threads are stretched over to one side a little also, and this causes the bolt to be locked into position. They can only be 'tweaked' over to one side so many times, then they will fail.
Also the bolts have a certain tensile strength, and can only be stretched so far, and So may times.
MANY, manufacturers plainly state to not reuse a head bolt of this nature. Reasoning, is that the bolt has been stretched, and stretching it again may cause failure of the bolt.
Plus, every time the engine reaches the operating temperature, it stretches the bolts, then the bolts contract once the engine has cooled off.
[Everything you always didn't want to know, huh?]
Two sources I have both say 217 ft-lb.

This is what I used on mine and it has been trouble free.

Hi Neil:
Have a close look at the assembly once installed.
It's quite possible that the pads or the caliper assembly "float" on the pins.
