I can't go any larger than 180mm on the front rotor because the larger diameter rotor will sit against the fork blade. The new thicker 180mm rotor with the ceramic pads hasn't squalled and it is quieter then the sintered pads that I have on the rear. I had the wife drop me of up the hill a ways. This gives me over five miles with no stopes and one light that is easy to catch green. I did this several times. I coasted up to around 20mph and slowed down. I alternated between the front and sear brake. The front brake works better because I can actually use it now that it is not squalling.

I have seen some videos of the pros having locked up brakes. Mums is the word as to why this happened. There are some disk rotors that have an aluminum core with a thin outer metal braking surface. I have heard that the aluminum sometimes starts to melt. I believe some of these problems occurred because of under engineering. This isn't the industries first try at disk brakes for bicycles. I believe they can do better with the right motivation.
