Brake Callipers

[harpmeister]

Just putting the callipers back together after changing the seals and was wondering if there was a specific torque setting for the bolts that hold the two halves together or is just the generic 22 - 30 ft lbs for a 10mm bolt.

Don't think Brembo ever offered a figure...but BMW did!  29 + 3.6 ft lb or 40 + 5Nm 
Ties in with similarly sized steering yoke cap head bolts that also mate with alloy threads.

I've never done them up with a torque wrench. I put anti-seize grease on them and do them by hand until they feel about right. I've never had a caliper fail because the bolts were too loose.

The beauty of Allen keys is that they're self-limiting in a crude sort of way - the long end isn't long enough to put too much torque on the bolt by hand (unless you're built like Arnold Schwarzenegger).

If you use a torque wrench, I'd suggest a torque somewhere towards the lower end of the generic figures to avoid overloading the aluminium thread in the caliper. I've seen 18 ft.lb quoted on a couple of bike forums.


Edit:
Well, there you go. Two totally different answers! 
Just shows the value of info you find on the internet forums.
Hopefully someone who knows more than me or Rob will come along.
