I know the shop manuals will have the torque specs. They are messy to dig through but hopefully this gets you going on the right path. Take a look and if you're still stuck i'll try to help you find them when I am less busy.
Cool. I found what looks like the Caliper Mounting Bracket Bolt Torque spec under Brakes04 > Convention Brake Systems > 04-11-17. To me it looks like its saying to torque the bolt to between 58-75FtLbs, if you could confirm thats correct, thanks.
