Gotta say something about the suggestions for centering center pull calipers. The punch method does work but is barbaric and unnecessary. 10 or 15 minutes with a file will result in flats (ala Campagnolo calipers) on the brake center bolt allowing the use of a cone wrench for centering the caliper. Or, a milling machine works if you have one. Jay Sexton Sebastopol, Ca

As Fred has pointed out, the socket will do the trick to center a set of sidepull calipers.

However, there is nothing like the following for fine tuning once the fixing nut has been cinched down:

For those who wish to use this advanced technique, locate the punch on the caliper spring right next to the centerbolt fitting and give it a tap. This can be very useful when a rondella dentata (aka Campagnolo toothed washer) is "indexed" into grooves in the crown or brake bridge boss that aren't ideally aligned for centering the caliper. Sometimes percussive maintenance is the right approach.
