Just replaced both front calipers and i need the torque on the two large bolts.My c.d is no help.

I don't seem to be able to find that information either, but I would guess 50 ft/lbs or so. I just pull them up firmly with a breaker bar, never had one come loose.

Blue (temporary) LockTite is good, too.

Does anyone know the correct answer ?

My manual shows 115 nm for a 1986 420SEL.

After cleaning the threads, I use blue loctite and torque all models to 85 lbs. Torque wrenches are onlt to be used to torque things. Also if you have the style where you dial the torque at the handle, you have to undial it to zero after the job.

Pardon me (I'm not Fred), but if you used your torque wrench to loosten a bolt/nut, it shouldn't make any difference which direction the torque is being applied to the internals of the wrench.
If you are saying that you reached the torque setting (it 'clicked') and kept on applying pressure, then that may be a different story, but I've never heard of a wrench being 'decalibrated' by doing this. I'd think that the internals would 'stretch' as if you were simply applying more torque, and that the only damage might be if you exceeded the rated limit of the wrench itself.
And I do agree with Autozen in that the wrench should always be 'unloaded' when not in use to prevent damage.

Yes, you can damage a "click" type torque wrench if you exceed the torque rating while loosening fasteners -- it can take quite a bit of extra "oomph" to get some out (like the Volvo balancer bolt -- 300 ft/lbs AND red LockTite...).

So long as you don't use more than 200 or so ft/lbs you won't hurt it, but why take the chance? A 24" breaker bar is a whole lot cheaper....

If you are using the "flex with a scale " type, you can bend them, 'nough said?
