Wow, I did not know that there was an issue with ceramic brakes wearing so quickly. This is my fourth Porsche but the first I ever owned with ceramic brakes. I knew one of the biggest advantages of having them was the fact they are so light. I was also under the impression that they lasted quite long as compared to regular steel brakes. I hope that this"Premature" wearing of the ceramic brakes is an anomaly.

I did a quick search on the forums and was unable to find anyone else with similar problems. I could understand why they would not be ideal for track use due to their expense.

Can you replace the ceramic brakes with regular steel ones?

I hope this all works out for you.

Yes, the tech used feeler gauges while I watched. It took less than 5 minutes, and the pads were fine on 2-3 occasions and needed to be replaced on two others.

 

Is this what your rotors looked like?

 

My car has 12500 miles on it. I just got the car so I guess I will see how they hold up. I have owned 4 Porsches and have never had to put breaks on any of them. Even my last car a cayman with 26000 miles had breaks like new.
Although I don't plan on tracking my 991 regularly, I don't like the idea of worrying about it if I want to take it on the track once or twice or drive it briskly on the street a little.
It is hard to believe that the Porsche engineers who typically over engineer everything would over look this issue.

 

Thank you for your thoughtful contribution.

To answer your question, only the rears failed. The fronts were completely unaffected.

You make some other good points which I'll think about and respond when I have more time.

Not at all. It's hard to describe because I have never seen anything like them before. They were like a smoothly polished metal sponge with shallow irregular depressions. I hope that helps.

 

Yes-thanks! the best color on the planet, but I'm biased and a sucker for silver

Doesn't hurt getting a little off topic here, calm things down a little

So where's your car now? Have you replaced the pccbs or what?!

Post pic please!

Yes, I had to cough up the $10K.

 

[QUOTE=jimmy348;4096183]Yes, I told the dealer about the track days. I saw no reason to hide the truth because:

- The dealer was well aware of my limited track day plans and saw no problem with that. In fact, they were as shocked as I that the brakes burned out and disagreed with PCNA’s warranty denial.
- The marketing literature bragged about the heat resistance of PCCB, so I saw no reason to be worried ahead of time.
- The only warnings about brakes and track days in the owner’s manual was to get the brakes inspected before each event. I did this religiously, and no problems were found until the rotors failed.

BTW this issue is water over the dam, and I’m stuck with the repair bill because the car was a lease. So a switch to steel was not an option.

"Going forward, my path is clear. A pair of replacement PCCB rotors cost $8000. The same rotors in steel are around $400. In my mind, PCCB are not 20 times as good as steel. Therefore, I intend to vote with my checkbook. Until Porsche installs brake temperature sensors and an on-off switch for torque vectoring, I intend to take my business "

Sorry to hear...When the PCCB first arrived, mantel others believed the marketing hype that PAG /PCNA pushed out.
Like your self, I voted back in 2004 via my pocket to buy other makes.
The sad thing is, after all these years Porsche is still pushing out this bull shi- of a marketing info.

 

Here you go. Love how it drives. Disappointed in PCNA.

 

Agreed.
