• The hole on the fork is smaller than the diameter of my brake nut. Any ideas? I'm using a 8mm standard nut and can't see any smaller diameter ones. Maybe see if someone can machine a half mm off the diameter?

    Is it painted? If so, using an 8mm hand reamer to scrape off the excess paint probably won't even touch the actual carbon fibre.

    There's more spare material in the fork crown than there is in the nut, so I'd favour making the hole bigger rather than making the nut smaller. If you take the nut down to 7.5mm, you're reducing the cross sectional area by about 28% on a component whose resistance to tensile load is all that's keeping your front brake attached.
