Centering old brakes

Just wondering if anyone has any tricks for centering the old side-pull brakes. Everything just kind of sits on a bolt, which is hard to tighten down and keep aligned. Any thoughts?

Tighten it, but not so tight that it does not operate. Then to center it you need a hammer and a flat blade screwdriver. Align the blade of the screwdriver so it crosses the top of the side loop if the return spring. Give it a gentle tap or two until it is centered.

Wait a minute before using a hammer. Check to see if the bolt holding the brake to the frame has a flat-spot on it's sides - in between where the bolt comes through the frame and before it gets to the calipers. Most have this feature so you can rotate the brake body with a thin wrench like this:

Cone-wrenches also can be used in place of an offset brake-wrench. Most commonly these flats need a 13mm or 14mm. This is much better than the old 'hammer-on-the spring' school of centering your sidepulls.
