Brakes are a pretty important part of my bikes... Anyway it's not the noise that bugs me so much as the vibration. I guess it's really not a problem since it doesn't do that under hard braking - i.e. it wouldn't interfere with handling in an emergency. I'll give it another couple of rides and see if it works itself out, if not I'll either file the pads down or replace them.

The shoes are oriented properly and I can't believe I wouldn't have noticed if they weren't before. Don't the pads come out of the shoes? (that would s**k if I have to throw away perfectly good shoes every time the pads need replaced...)
