when drilling forks for caliper brakes you would want a 6mm hole on the front and an 8mm on the back.

6mm through if your brake has conventional nuts, 8mm on the back with a 10mm spotface or counterbore if it uses Allen key tube nuts

Thanks. I take it spotfacing is to provide a flat surface perpendicular to the thread for the nut or bolt head to rest on.
