Ok I have an 2005 GT3 996 with PCCB brake system. it has 34k miles. Don't have a clear past history as to track or not. But Ceramic Brakes are squeaking at low speed. I completed one DE event & looking to do more so:


1 - When do you replace these?
2 - I was told by some that remove the Ceramics & install regular top quality brake system to be more cost effective??


thoughts
Thanks

 

I would say remove them if you had less than 10k miles on them, but with 34k miles you should just enjoy them until they are toasted. replace them with steel when that time comes.

 

I have them on my 2009 Turbo and when at colder temperatures or car/brakes haven't been washed they do squeak a little at lower speeds. Do you have the original brake pads?

 

If your pads started squealing after the track day, then you should be fine. They typically glaze a bit, as you're running them super hot. After a few days of street driving, the glazing wears thru and they quiet down again. If they don't, you might as well replace them, as you may be down low enough to where the rivets are scoring the rotors. That's expensive!

 

Personal opinion: Put the ceramic rotors and pads on the shelf for when/if you sell it and get yourself some steels for the track.

 

this is what i've bring hearing. Is this what you have done?

 

Forgive a potentially dumb question, but I thought the whole purpose for the Carbon Ceramic Brakes was for heavy track use. Seem to be overkill for daily driving or even spirited road driving. Is your comment based on the cost of replacement with heavy track use? I've seen similar comments before, makes me wonder what the purpose of CCB is. If cost were no object, does your comment still apply? Or is it based on performance concerns?

 

Cost, and not a trivial amount (~20k), for replacement.

 

Curious myself. What kind of life are the CCBs seeing when the car is tracked and street driven? The original thought before real-world experience was widely shared, was that these were 100k brakes.

Do the pads need replacing when going to steel brakes too?

 

If you drive on street you will not need to replace them (~100k miles). If you track, they wear at a similar rate as cast iron rotors - at least that's what I've been told. I'm going to try them on my 991 GT3. I will track the car a bit (I have a dedicated racecar for primary track use) and see how they hold up.

MovIt makes CCBs that can be refinished and supposedly last forever, but they are north of $20k for a set.

 

Thanks for the input!

 

I have steels on my car. It did have pccb. It's cost for track use and pad selection. If cost were no object I don't know which I'd prefer. Pccb is lighter. I like feel of steel brakes. My steel don't fade that I can tell either.

 

It's definitely uncertain drop of 10k in a bucket. I probably should just skip them, but I drove BMWs latest generation of CCB on track in 2013 and they were staggeringly good. I really want to see if Porsche has moved the capabilities forward with their 3rd gen - which are only now available on 918, 991 GT3, 991 Turbo/S

 

PCCB are perfect for road use.

Very much useless on track. Brand new pads lasted 2 days at SPA Francorchamps on my old 997 Turbo. They were down to less than 50% - so time to replace.
