Gee Chuck, of course heat is how brakes work. How about if the pads are 300 deg cooler, how much cooler is the fluid, how much more consistant is the pad temperature, how much more consistant is the Mu? Maybe, just maybe there is just a bit more to good brakes than just being able to lock the brakes.
Blah blah blah. Thanks ...

It will increase if you are able to stop sooner. or stay the about same if you stop in the same distance. Turning speed into heat is how brakes work, Jay. BTW, the KBS's have uprights that allow mounting dual calipers just like your car, but few people run them on KBS's these days for some reason. I personally like that dual caliper setup very much. But I like the large outboard rotors of a Sidewinder even better. The KBS is about about as light as one can make a F500. The addition of Rotaxes to them required some frame strengthening vs. running a Kaw.
