I believe the torque spec for the caliper bolts is 115nm, or about 85 lb ft.
The caliper bolts come with a Loctite type of dressing on them. Many people do not replace the bolts. I would suggest you at least use some sort of Loctite on them. Safety item-
I use 80 lb ft for the wheels. Torque them evenly using a criss-cross pattern.
