PCCB to Big Red Brakes standard on S
Hello all,
Can you go from PCCB to Red Caliber Brakes on a 991.1 C2S? Found a a 991.1 but it’s fitted with PCCBs. I will not be tracking, only normal driving. When these wear out can normal brakes be fitted without modification when the time is needed? Any and all advice please on PCCB to Red calipers and brake system is welcomed. If anyone has done this please add in an est. cost please.
Thanks

There are companies that sell iron rotors that are direct replacement for the Carbon rotor and pads that fit. Girodisc is one company.
Mist folks want want to convert to irons for track driving, not the other way around.

My two cents - there's no way that you'll save money over the life of the car by doing anything to the brakes. Easiest approach is to run w/ what you've got and enjoy the numerous benefits of PCCB.
FWIW - I have PCCB on my GT3 and I intend to track it w/ them. If somehow (and it seems really unlikely) I need to replace them, I will.

^^^^ This! They're great brakes and provide a lot of benefits. You'll gain an appreciation for them and their differences, just like you will for other aspects of the car as you use it. Good luck with everything!

It's hard to imagine wearing out PCCB, street driving. Unless you do >50k miles /year for 5-6 years or so. Especially if you use engine braking, like many of us. Its much more likely you will chip a rotor. Be very fussy when removing or installing wheels on a car with PCCB. Get the special studs or Centerlok tool for low risk, and carefully inspect rotors anytime a shop does any wheel removal. They won't want to own up to chipping a rotor. Otherwise, PCCB are super brakes.

Street Driving - it will probably take you over 100k mile with a mix of highway and city driving before you need to replace the carbon rotors.

Most folks want want to convert to irons for track driving, not the other way around.

Depends on the driving, but I don't think PCCB rotors will ever wear out in normal street driving. If they do, you can replace the rotors with iron or aftermarket carbon ceramics...certainly would be crazy to get OEM rotors at 3-4k EACH. I don't think getting new rotors etc from S model would be worth it...you can find the correct sized iron rotors that fit PCCB calipers so worst case you can do that. Replace pads at 50% is all you should ever have to do.
I know that in my last cars with iron brakes, I've never had to replace the rotors up to 160k miles. My Boxster was over 50% at 50k miles. Mostly highway miles.
The brake pedal feel/bite is really satisfactory. Its hard to go back to more mushy iron setup.
Traditional big brakes kits are a horrible idea because they're really heavy and its rotational weight... worst kind for stopping and accelerating. Manufacturers intentionally install the smallest rotors they can to match the performance of the car to reduce weight/enhance performance, including smaller rotors on rear etc. What's great about carbon ceramic rotors is they're actually lighter weight AND bigger than traditional iron setup.
The only downside is the cost of the option on new cars. Used cars aren't going to be more expensive because they have PCCB. The option would be mostly ignored as far as value, meaning they make even more sense on used cars, but I'd definitely have them inspected for wear. Even on a new car the additional up front cost could make up for replacing iron rotors 1-2 times in during the life of the car.

As an aside, my Panamera has 420mm PCCB up front with 10 piston calipers. I still can’t get over how big they are, as big as the wheels that were on my first car.

Does the 991.1 have 410mm rotors for the PCCB? This is a good conversion if you must have iron brakes, get the larger rotors and you can re-use the calipers.

Very much so, front and rear.
991.2 PCCBs 410mm front and 390mm rear, compared to 350mm front and rear for PCCBs on the 991.1.
I had a 991.1S with PCCBs and my 2018 991.2GTS also has PCCBs. They are just massive on the 991.2.
The S rotors on the 991.1 are 340 mm front and 330 mm rear, in comparison. (S rotors on the 991.2 are slightly larger on the front, 350 mm front and 330 mm rear.)
