From a 3 year old article on Mercedes vs. Porsche's introduction of Ceramic-Composite Brakes:
In addition, the PCCB discs are coupled with all-new metallic pads that develop extremely high and very constant friction during deceleration; brake temperature becomes a minor factor because the PCCB provides fade-free braking almost regardless of how hot the rotors become. Wet-braking capability also is improved because the new brake linings do not absorb water as conventional linings do.
Originally posted by krazik IMO A properly designed system shouldn't fade, especially in a 30 minute session.
I'll assume you are referring to a properly ducted system, too. I think everyone here has forgotten that the mass/heat capacity of the rotor is offset by the need to keep unsprung weight as light as possible. A properly designed system fades on the last lap in the last corner
And yes, Schuey and other experience brake fade, especially when running on full tanks.
you do have a point, but most of us don't have the budget of schuey to redesign my brakes for each track day, I'd error on the side of more mass to than less. Gives you the largest possiblities for all tracks.
Sorry for the long delay in updates. Its been slow going the last couple months.
Well I got the fronts complete and in working order and got a chance to try them out at the new fernly/Reno track.
They seemed to work quite well. Very good pedal feel and absolutely no fade. But then that was to be expected as the fernly track is very easy on the brakes. Only one really hard braking zone in the current configuration. When I got the car back home I tore the front brakes down for inspection. Turns out the the lower ball joint protudes further out than I thought when the suspension is compressed. Doh! This resulted the casting rubbing up againt the rotor until the cast was shaved enough to no longer rub. I have since taken a die grinder to the casting to generate a little more clearance. See the pics below. If this continues to be an issue I'll have to increase clearance by redesing the brackets etc. I might also have to install longer lug nuts as well. For now I'll continue to test it as is.
I'm currently making brackets for my new rear brakes. I'll be using the rotor and hats from my Pinnacle setup (12.2" dia 0.81" thick rotors) along with an Outlaw 2000 caliper. I currently have no plan to keep the ebrake, hopefully that doesn't become a problem.
I should be receiving parts early this week that will let me complete Phase two, dual side by side master cylinders. I hope to have all of this put together by the end of this week but who knows. Either way I'm planning on bringing it to SOW early Aug with SV to do some testing of the new setup.
