Thanks a lot, I have read some of the X-to-win series, but I haven't read all of them yet.
Horse, your post (which was very helpful thank you), only seems to explain where the rotors crack, not why, but I may guess it is differing rates of cooling.
I have never hit puddles after heavy braking, period. Also my rotors have never warped either.
So my current thinking is that rotors are intented to be a homogenous mixture of carbon silica, and iron. However as everone knowes truly homogenous mixtures are impossible. So the cracks are forming on the phase boundaries, and the different phase have different cooling rates, therefore causing the cracking.
Back to practicality, what to do about the rotors.
1. Upgrade my brake system, larger rotors can handle more heat
2. Upgrade my rotors, are there better quality rotors out there?
