when i refit the calipar bolts, i normally do them up as tight as possible, using a ring spanner, and then using a hammer, gently tap spanner to tighten them, (which i have seen many a techie do,) with no problems, but if you need torque settings, then you could always get a haynes manual. just remember to put a smear of copper ease on bolts.
