The ultimate upgrade for your Porsche is the ceramic composite brake with yellow-coated aluminum fixed calipers. These larger cross-drilled brake discs offer significantly more power, extraordinarily short braking distances, the highest level of braking security, and greater control in challenging driving circumstances. Additionally, because ceramic brakes are 50% lighter than gray cast iron discs, they provide superior grip, more comfort during driving and riding, and increased agility.

Ceramic Composite Brake from Porsche (PCCB)
The term “Porsche Ceramic Composite Brakes” (PCCB) has come to represent something that Porsche has always given the highest emphasis. because Zuffenhausen sports cars have always had incredibly strong and long-lasting brakes. In practically every segment they compete in, Porsche’s brakes are the standard. Therefore, it is not unexpected that Porsche was the first automaker to adopt ceramic composite brake discs with involute cooling channels. In the interim, all Porsche super sports vehicles come standard with the Porsche Ceramic Composite Brake.
PCCB or not to PCCB?
In a recent industry piece, it was discussed whether Porsche’s PCCB (Porsche Ceramic Composite Brake; denoted by their yellow calipers) were the ideal brakes to utilize for track days (including high performance driver education, autocross, etc.) or those who are heavy-footed on the “slow” pedal. According to Paul Watson, a technical representative for Porsche Australia, iron brake discs are advised above carbon discs for drivers who apply severe pressure to the brakes or who track their vehicle. Why? Heat is a problem since it can quickly deteriorate the carbon fibers in PCCB discs. The more friction (heat) builds up as you press harder on the brake pedal, stressing the carbon rotors more quickly than iron or steel rotors would in the identical braking condition.
You might recall that Porsche once claimed PCCBs could last the entire life of the car. This may be the case if the owner rarely uses the car, keeps it in a collection, or brakes lightly when necessary. However, spirited drivers and those who press down firmly on the brake pedal, even during any “track” activities, run the risk of PCCBs wearing out sooner than you expected. With front and rear replacement costs in the $20k+ area, you might want to reconsider putting gorgeous PCCB’s on your next Porsche.
-Full-throttle race cars, where the driver seeks the lightest unsprung weight for the best acceleration and deceleration (measured in milliseconds) and has the financial means to often replace worn brake components.
-Those who use their brakes seldom and want the distinctive appearance of yellow calipers and carbon-ceramic rotors.
-Those who have an obsession with keeping their car as spotless as possible, as carbon brakes greatly reduce the amount of brake dust that collects on the wheels and vehicle (although it is important to note that there are ceramic brake pads available for vehicles with iron discs who want to reduce brake dust, but keep in mind ceramic pads typically require a bit more pedal effort to be applied than semi-metallic brake pads do).
Porsche Carbon Ceramic Brakes: An Explanation of Technology
Porsche Carbon Ceramic Brakes, a joint venture between Porsche and SGL Carbon, were introduced in 2001 on the 911 GT2 following the technology’s introduction to the world at the 1999 IAA in Frankfurt.
The ceramic core of PCCB discs is reinforced with carbon fiber, and an extra ceramic friction layer is placed on top. Carbon ceramic discs are 50% lighter than cast iron discs of the same size after 20 days of production. More responsive handling and better acceleration are the results of the reduction in unsprung and rotational mass at each corner of the car.
PCCB enhances braking efficacy in addition to improving handling. The ceramic coating increases the friction coefficient, which enhances the initial “bite” when using the brakes. When trying to brake late for a corner, this boosts confidence.
When coupled with carbon fiber, a material made of metallic silicon and silicon carbide also provides better wear than conventional discs. As a result, brake fade is lessened during extended durations of use. Additionally, because the material is more acclimated to operating at greater temperatures, the likelihood that brake discs may distort and ‘knock back’ the brake pads is decreased.
All of this results in a consistent brake pedal feel, which boosts a driver’s comfort level when using the brakes. Any 911 that is going to see a lot of track action needs a PCCB.
Describe PCCBs.
Small grains of carbon fiber are shot through silicon resin to make PCCBs, which are then molded into brake discs with holes added radially to create cooling vents. The mold is put under intense pressure while it is heated to 1,700 degrees Celsius and then cooled. The entire process takes the substance around twenty days to complete before it takes on its ultimate form, silicon carbide. After that, a second ceramic layer is applied to the raw disc, and it is coated to prevent corrosion.
Since silicon carbide has an extraordinarily rigid, crystalline structure, it was first utilized in brakes in the 1970s. The Porsche 911 GT2 was the first production car to use these powerful brakes in 2001.
The ceramic coating and diamond-like core together increase the friction coefficient and nearly eliminate corrosion. PCCBs can last the whole lifetime of the vehicle, even in cold locations where salted roads can pose significant dangers to iron components.
Heavy brakers and trackday champions purchase the incorrect brakes.
Brake discs made of carbon ceramic are quite pricey. That is common knowledge. Although a technical specialist for Porsche suggests (contrary to a response from a Porsche spokeswoman) that it may be wiser to give them a swerve if you’re enthusiastic about trackdays or are just particularly forceful on the brakes, optioning them onto a new 911 Carrera S would cost you $18,770.
If you play in club days, we always advise using iron discs since heat buildup will weaken the carbon fibers in the disc.
This goes against what most people believe to be the USP of carbon discs, which is their ability to take a beating while being repeatedly heated without experiencing brake fade. Additionally, they have a very lengthy lifespan.
Watson laughed when questioned about the PCCB (Porsche Ceramic Composite Brake) discs’ lifespan and declined to be dragged into making predictions about how long they would last.
At the 992 launch event at Tailem Bend, he said, “We learnt that lesson a long time ago. “When we first introduced the discs, we told people they’d practically last for the life of the car, but people were participating in several trackdays and reporting to us that they had worn them out,” he said.
Therefore, even if reducing unsprung weight at each corner and other dynamic benefits are evident, we questioned who the target market for carbon ceramic brakes was.
Because of the reduced unsprung weight, they added, “Porsche Ceramic Composite Brakes (PCCB) offer greater benefits in terms of braking performance and handling and are thus the preferred braking option for many Porsche drivers.”
“Drivers who frequently drive their Porsche on a circuit, such as amateur racers, may choose to use our steel brakes because they still provide incredibly great stopping power and are less expensive to maintain.”

On my 911 Turbo S, I had Porsche Ceramic Composite Brakes (PCCBs). In terms of stopping power, they were practically EYE-WATERING, and from an aesthetic perspective, they were CLEAN, leaving almost NO brake dust on the rims.
Originally, Porsche PCCBs were designed to “last the life of the vehicle.” Porsche has since stated that PCCBs are no longer recommended for “club day” track use due to the PCCBs’ higher wear patterns and their prohibitive repair costs. or similar language.
The cost of PCCBs for the 718 Spyder is $8,000. If you want them painted in the softer HI-GLOSS black, add $900.
In light of the aforementioned, what is the general consensus with regard to ordering PCCBs as a possible option for the Spyder? Do they justify their price?

In-country technical representative for Porsche Australia. When the topic of carbon ceramic came up
When asked about brakes, Watson shocked his interrogators by saying, “If you’re doing club days we’d always advocate iron discs.” Given how carbon ceramic rotors have been marketed as a top-secret weapon for track days, this perspective is unexpected.
Watson noted that “heat build-up will deteriorate the brakes and ceramic discs can degrade if you’re harsh on the brakes.”
When Watson adds, “When we first released the discs, we told customers they’d last essentially for the life of the car, and people were doing a lot of trackdays and coming back to us saying “I’ve worn them out,” that is when the context of his statement comes into play. The problem is not with carbon brakes’ pure performance worth, but rather with their cost-to-performance ratio when compared to iron rotors.
Brembo once touted the 100,000-mile lifespan of their SGL carbon ceramics. The business
has revised the language on the page to state that they outlast cast iron discs by a factor of four and experience significantly less brake pad wear. Obviously, results will vary.
The Porsche forum supports Watson’s story. If the Porsche Carbon Ceramic Brakes (PCCB) are worth their new and replacement costs, there is disagreement in forum postings that date back at least five years. Porsche charges $9,210 to add PCCB to the 911 GT3 and $8,520 to add PCCB to the 992-series 911. an additional set of rotors
The cost of the front axle is $11,500. Porsche-specific aftermarket carbon brake kits that can be repaired,

YouTube is flooded with footage showing Porsche owners replacing the carbon ceramic brake rotors with a pair of Brembo steel discs and keeping the PCCBs until the owner sells the vehicle. In that regard, carbon brakes are infamous for being weak. Another extra money is available if the local mechanic cracks the rotors.
Cast iron road discs should not last as long as carbon brake systems, which are lighter, more stylish, and should last much longer. Additionally, they don’t produce brake dust, which is helpful for the fish and survey participants from J.D. Power.

are for people who don’t like washing their wheels, he retorted. An advantage is that they don’t cause brake dust to accumulate.
How long is Pccb good for?
We have followed my dad’s 991 GT3 together. I don’t think PCCB would function any substantially better than the amazing steel brakes, which are simply amazing. On the street, PCCB rotors are expected to last 100k miles, but when utilized on the racetrack, they wear similarly to steel brakes, albeit a little more slowly. The cost of replacement is the main difference. You will have to pay $17,000 for PCCB rotors and pads on all four corners. To me, it seems obvious. Get the steel brakes if you race a GT3 or GT4. I must admit that I haven’t used a Porsche PCCB personally, but given how well the steel brakes work, I’m not sure how the extra cost for track use could be justified.
Brembo produces Porsche brakes, right?
Brembo brakes, which are included on every Porsche, Audi, and Mercedes models in the rankings, are utilized by 92% of the German vehicles in the Top 50.
Why do Porsche brakes perform so well?
Porsche Original Brakes are able to maintain a consistent braking action even under heavy loads because of technology transfer from our race vehicles. The cross-drilled and internally vented brake discs offer enhanced wet braking and ideal cooling. The enclosed monobloc design of the brake calipers, whether they are available in anodized black 4-piston or red 6-piston aluminum versions, provides great stiffness and pressure point responsiveness, low weight, and tight pedal travel.
