The CENTERING is set by holding the outer Cap nut with a wrench, then holding the brake clamped on the rim, then loosen/tighten the nut on the other end of the brake mount/spindle.... or at least that's how it's supposed to work... usually, the back nut is a nylok nut and wants to turn the entire caliper spindle... trial and error will get the caliper centered quicker, IMO
i've watched someone use wooden door/window carpenter wedges to center the caliper, then loosened/snugged the back nut down... it took a few tries that way too...
and then.. there's the Third Hand Tool... not economical for home repairs, usually.. the cheap spring ones don't work well, and the Park Version likes to slip off at the worst times, do a half spin with a twist,, and land on my big toe... ouch!
I mostly use it on Center pull brakes when setting centering and cable length..... the BMX "under the chainstays" versions most recently.
here's the toe killer.. Park doesn't have them on their web catalog now.. they have a spring type tho...
