Looks like the caliper to knuckle bolts are 98 foot/lbs., or about what you would tighten a wheel lug to.
I doubt most professional mechanics would use a torque wrench on these bolts, experience gives us the right feel for these things.
BTW, using the size of the hex head to describe a bolt isn’t meaningful. What’s important is the diameter of the threaded portion. For example an 8mm bolt may have a head that takes an 8, 10, 12, or 13 mm wrench.
