and other (especially Wienmann) sidepull brakes will get sloppy if they are
run with the spindle nuts set too loose, however I would be REAL hesitant to

terms of longevity. Seems to me that you'd compromise the integrity of the

The overall brake boss on a Campy caliper is 17.5mm, the hole 5.8mm plus
clearance. The bushing needn't be very thick (.5 to 1.0mm) and if done
properly would not compromise the strength of the forged arm. Of course, you
would void the factory warranty. I would think a sloppy arm would be more
prone to failure because everytime you use the brakes, you're slamming them
in the bolt hole.
