This part of the thread has been very enlightening for me. I had a situation a while ago where I had recently tightened up my pad adjustment and I was getting a tiny bit of scraping but it went away when I pulled the lever slightly. I thought I must have been imagining it. Now I know. FWIW, that was with BB7's.
My opinion on BB5's is that when it come time to replace the pads, use it as an excuse to upgrade to BB7's. The BB5's are a complete pain to get working well.
