Just changed the pads on my BB7s. 203mm front and 185 rear. It had tons of stopping power with the stock (semi-metallic I believe) pads. Once finger braking was all that was required and I could put myself over the bars with one finger. Now, I can still endo if I really try but it takes a lot of effort. They still aren't fully broken in and they're getting more and more powerful as I use them more. I'm hoping they get back to the original power level. They only have a couple miles on them and I haven't gotten them real hot yet so I'm probably jumping the gun here. Besides the loss in power, the differences I can see so far are better modulation and they don't get more grabby as they get hot. How does the friction coefficient of ceramics compare to semi-metallics? What about break-in procedure?
