Removing old 'V' brake pivots?

[Taka]

I've just upgraded my Specialized Hardrock to hydraulic disc brakes.

Has anyone got any tips for removing the old 'V' brake pivots from the frame and forks? The flats are too small to take a spanner without spinning and I don't want to end up with a mangled mess!

Help!

Never mind!
