I've read a lot that say's PCCB's are not good in the winter, especially 1st gen. THoughts? Can I use them w/ snow driving?

 

Assuming carbon ceramics need time to heat up, they might not be as optimal as metal in day to day driving...

 

Had an 05 TTS with gen 2's and never had any issues in cold weather.

 

Carbon ceramic brakes on aircraft have bad problems in the winter. The operating cost on aircraft allow for the replacement of the discs with a little less grief than the PCCB's on your Porsche do. These brakes absorb water causing the discs to become brittle, reducing their durability, and the obvious performance decrease.

 

Don't have that problem with the F-16, there have been a few days when
it would have been nice to have snow tires though.

Recently Gulfstream and Cessna have both issued Customer Bulletins concerning the issue. I know because, the powers that be, sent me ~6 emails about it.

 

Great so let me get this straigh....I am ok with them on my Porsche Turbo but better make sure to swap them out on my Jet?

 

I'd swap them out if you can on the TT. It's worth it with just the damage to one corner.

 

They work fine on the B-777 also.

a lot of people will tell you they work fine in the cold and rain.. and they do. But I wouldnt say they are great in the cold or rain imo.

 

NOOB question....if I walk up to a 996TT, how do I tell if it has the PCCB option? I assume they look totally different. Anyone have a picture?

 

Yellow calipers and no rust on the rotors.

So Red calipers are the standard with typical pads?

 

I'm 100% positive porsche would not sell a car that had brake issues under any real world circumstance.

 

From a few different sources;

"The new composite brake pads also last around twice as long as conventional ones. What's more, the new PCCB pads do not absorb water, making for outstanding performance in the wet."

"Brakes featuring CCM discs offer much more responsive braking as well as consistently excellent performance in intensive use. One of the most obvious advantages to adopting them is their exceptional fade resistance - fade in fact compromises the driver's feeling of control when it comes to the pressure required on the brake pedal and responsiveness.
The CCM discs have a longer life under normal conditions, a fact that has clear financial advantages. Furthermore, even with continual track use, CCM brakes offer greater resistance to wear for better durability on track. The CCM braking system also cuts around 15 kg off the car's total weight which not only improves overall performance but also reduces unsprung mass and thus improves vehicle dynamics and ride comfort."
