If we could get past the acrimony, I'm very interested that different owners have had different experiences with their brakes. I believe that I push my brakes pretty hard on the track. The east course at Pocono is almost an AutoX course. It has a lot of turns and a lot of braking. Peak speed on the straight, for me, is a little over 100 mph, and there is a really tight hairpin. I also know my sessions are long compared with autoX. Yet, the only problems I have had are the following. Occasional smoking rear pads, One instance of boiling brake fluid (with year old fluid). One instance of being low on fluid (that day involved six 30 minute track sessions at Pocono) One cracked rotor and strange non-contact areas (showed rust ring in middle of rotor circumference) on both front and rear rotors (from that same 3 hour track day) . Both the above were solved by replacing pads, brake fluid and replacing front rotors with slotted only FrozenRotors.
I cannot say I have been aware of any real brake fading, except for a spongey pedal at the end of the 3 hour track day. I also know that I often brake much harder than others in my group (HPDE 2), because I close with those in front of me at the start of turns.
I have never been to the track with stock rotors. Had Race Concepts d&s until one front cracked. Rears are still Race Concepts, Fronts are slotted Frozen Rotors. I had Metal Masters all around for my first 2 track days, and Axxis Ultimates front with Metal Masters rear ever since. Have had Race Concepts SS lines from the beginning. Used ATE SuperBlue first (old boiling brake fluid), now Wilwood 570 (just as good and cheaper - $5.75 for 12ozs)
Braking performance is also related to suspension (not about fade, about maximum tire grip) Both Ben and I are running pretty stiff springs for our car weight. Maybe that helps us with overall braking performance. That might well explain Cazzer's observations about needing better brakes. An OEM sprung SVX is a real floater. Also, I'm running 245-40/17 BFG KDW-2's, good grip, but not slicks or R-compound. Maybe if I was running slicks, I would have a lot more problem with fade.
So, why is my perceived braking experience so much different from some others? Are you running OEM or other plain rotors? Fluid, pads, lines??? What tires are the faders running, R-compound, slicks??? Also, exactly what kind of sessions result in fade? AutoX? HPDE? Time Trials? Wheel to wheel 30 minute sprints?
