My point was that the basic layout and lack of COOL down time between braking zones at LRP can push pads near or over the thermal operating range quicker then at track like NJMP where you have more potential to allow the pads time to dissipate that heat!

And it is not an erroneous comparison!

I could be wrong, but I beleave it uses all four wheels. According the manual (http://www.porsche.com/all/media/pdf...ayman_PCNA.pdf page 63) it says it brakes each wheel independently.

You're right on the front brakes normally causing fade as they do the most stopping. Overall I don't think it matters which caliper boils the fluid - it all works off the same master cylinder. If you have dual MCs, then it might be different, but I'm guessing it would still create a soft pedal.

One thing I think you're missing is the high average speed at LRP. That track, while short, gives LOTS of air to the brakes. For most cars, LRP is about 20mph a lap faster than NHMS. I've never been to NJMP, so I don't know average speeds there.

CWhaley

I run both tracks and do not agree with that... LRP you can end up running with a small or large group and in traffic your airflow is not greater becuase of the extra speed (while in comparison it is not much greater then either Lighting or Thunderbolt)

Bifurcate? Fred, another attorney? (to wit, "bifurcate liability (my fault) from damages (hitting the wall)

FYI, nice pic in Pano of you and the mean white machine.

Of me? I haven't see that...

FYI, A bifurcation is also a dental term that refers to a dual-rooted tooth, like a lower molar.

Some folks keep bring up boiled fluid. Sounds like Paolo was getting the pads too hot for the pad materal not boiling the fluid. Fluid boil = long pedal. Pads cooking off = less torque. Paolo what were you getting long pedal or less torque per pound of pedal pressure?

better pads, better cooling, less braking via better method and perhaps PSM intrusion. All braking issues tend to improve with better air flow to the brakes.

heheheheee!!

Frank - is your car white? And if it is, I sure am not going to use you to whiten my teeth

quality!

There is truly a lot to this. Few years ago I had a student that was late braking and hammering them. We tinkered with the methods and got better lap times times with less sharp braking and improved method of strong ramp up in and taper out. A year or so later he mentioned that he was not going through brake parts as fast but was still faster than before.

gums

No, it's more like gray. So, I guess you weren't talking to me!
Anyway, my hygienist does all our whitening, so no need to worry.....

Veloce Raptor

Absolutely. I see this a lot. "Softer" feet and hands = faster smoother laps with the car doing more of the work and the driver just guiding it along.

Adam@Autometrics

Perhaps I missed it, but I didn't see if he mentioned whether the pedal was soft or firm when the car would not stop. Overheated fluid will give a soft pedal (and it gets progressively worse, so it doesn't sneak up on you), but overheated pads or glazed discs will give a firm pedal but little stopping power. On the Koni 997s (before going to motorsport ABS System) occasionally we'd get ultra-firm pedal with almost no stopping power. Overheating fresh SRF (even with PSM) is not easily done, and orange pagids are generally good for street tires, so I wonder if it was the PSM/ABS issue.

Kurt, I was getting no torque at all.......
