I could only find reference to the front caliper bolt, which is a 18mm. I went with 85ft/lbs up front (seems like a lot).

The rears were a 16mm bolt I believe, and I went with 65ft/lbs.

I have ~600 miles on everything, and the car needs an oil change, so I will check torque values in a few weeks to make sure nothing has loosened.
Front brake torques: https://www.newtis.info/tisv2/a/en/f...rakes/GfqyNpyB
Front caliper to stub axle is 110Nm (which is 81ft-lb, so 85ft-lb is within a reasonable tolerance).

Rear brake torques: https://www.newtis.info/tisv2/a/en/f...rakes/GfyH0Hrd
Rear caliper to stub axle is 50Nm +60 degrees rotation, with replacement of the bolts required, as they are stretch-to-yield bolts.
