If I recall correctly, when drilling forks for caliper brakes you would want a 6mm hole on the front and an 8mm on the back.
I had a fork drilled a few years ago by my LBS for a fiver. Worth asking as its a small price to pay to avoid errors.

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.
