Ah - I usually just remove the axel, and squirt my finish line pro waterproof stuff everywhere - and refit.... or my M535's, remove outer plastic cap, get squirting, and refit cap - that's it.....
My Looks Pro Carbons were remove axel like the M520's- so just re-lubed and refitted.
I have never touched the Record Looks on the Herety..that's how good they are.....and why it's just about the only Campy bit on my bike.....(other than the seat pin bolt).
As for new Ball Bearings's.....erm.......erm...new pedals anyone.............
