Carbon Ceramic Brake Demystified
Share with you is a research I have done for our CCM brake development.
I have been reading hundreds of threads in this and other forums about "pccb" or not "pccb" or something to that nature and for sure many more to come but I have yet seen a fact sheet comparing these two type of rotor materials:
Carbon Ceramic - Known as pccb (Porsche Carbon Ceramic Brake)
Cast Iron - Known as "Steel"
So here is.
Data source: http://www.sglgroup.com/cms/internat...ml?__locale=en
This chart with my comment and note should satisfy most of your query for a clear and true understanding between two type of rotor material, and their respective advantage and disadvantage which hopefully can help you make a better decision.
Analysis is based on the data published by SGL (Now owned by Brembo) and my reference from various material data book. My comment was duly verified by Geoff Whitfield - Engineering Manager of Surface Transforms.
This presentation is deemed to be accurate at the time of publishing.
If you still have question please feel free to address, in the meantime please keep the discussion focused on the material fundamental and their respective characteristics.
For those who are interested in learning more, we have a more comprehensive collection on CCM including mfg process and experiment data etc. here:

Thank you.

Thanks. I'm ignorant on this topic. I hope my questions aren't too basic. But of the 11 measures you have listed, which are most important? For example, how important is flexural bond strength compared to, say, density (and by extension unsprung mass), or maximum operating temperature? I would imagine these are not all of equal importance.
Are there some which are more important in terms of helping fade vs durability, and for applications related to racing vs street use, etc?
Obviously the choice of which rotors to get, also depends on other factors like cost, even brake dust I suppose!
I would really appreciate if you could perhaps help me summarize and condense this data into a rational approach to understanding rotors. Thanks in advance!

I'm looking for the executive summary?
No dust on wheels = priceless.

It's typical gray cast iron....cough cough....does it really matter?

No brake dust as well for me "camp". The other thing that would always bother the sh$t out of me was when I washed steel brakes (iron), before you get a chance to dry them they would turn to rust.

The car, wheels and suspension were designed for PCCB's. All the early review and press cars had them. It would be great to see the effect on acceleration between two otherwise identical cars. If it's anything like the huge difference in performance on the new Mustang GT350 because of reduced unsprung mass, it would not surprise me at all...
