Thanks for all the great responses!<img src=icon_smile_wink.gif border=0 align=middle> Actually, I had, already, ran across the Vintage Brake page. Until then, I really hadn't thought about the CB450/CB72/CB77 brake. From reading that page, the Honda brake has longer shoes and actually more area than the Yamaha. Of course, what specs suggest, and the way things actually work in practice, are not always the same, hence my question. <img src=icon_smile_big.gif border=0 align=middle> However, it seems like the general consensus is that it's very comparable in performance and is certainly more plentiful. I was aware of the difference in axle sizes, but as suggested here, it probably exists, even if I have to do a little research to find it. Of course the easist way to have good brakes would be to stick with dual disks and be done with it. Oh....if I were only that smart. Which, of course, I'm not. What I want to end up with is something that would have looked totally at home sitting in front of The Ace Cafe in, say, the early 60's. Probably no disk brakes to be seen there. I know.....no Yamaha's either, but you get the idea. Once again, thanks for the replys.
