Technical expert of Porsche had a surprise reveal about ceramic disc brakes during the launch of model 911 series 992 version 2020.
During the launch of the Porsche 911 series 992 model in Australia in 2020, Wheels magazine had an interview with Mr. Paul Watson – Porsche technical representative in the country. When the exchange turned to carbon-ceramic disc brakes, Mr. Watson surprised the reporter by saying: “If you drive on a racetrack (or an unrestricted road), we always recommend braking. iron plate only “.
This is really a shocking information, given the long time that ceramic disc brakes have been introduced as a weapon on the track.
Mr. Watson explained that “ceramic disc brakes may be worse if you brake continuously at high speeds” and that “heat buildup will reduce the quality of carbon fiber in the brake disc.” what else
The context for Mr. Watson to give the above information is when he said, “When we first released the ceramic disc brake, we told people that basically when the car enters the waste dump, it brakes. new, when people bring their cars to the track and then come back and tell us “Damaged brakes”. “The problem is not just stopping at the operating value of carbon ceramic disc brakes, which is a correlation between cost and performance compared to iron brakes.
Brembo advertised its SGL carbon ceramic disc brakes with a life span of 100,000 miles (160,000 km). The firm later changed its words saying that it had four times longer lifespan and the brake pads were obviously less damaged than the cast iron disc brakes. Fuel consumption of vehicles is certainly different.
A quick tour through any Porsche forum can find evidence for Mr. Watson’s words. Five years ago, there were debates on the forum about Porsche Carbon Ceramic Brakes (PCCB) carbon disc brakes that are good for its price and replacement cost. Porsche sells PCCB brakes for $ 8,520 for the 911 series 992 and $ 9,210 for the 911 GT3. The price replaced a front axle set of 11,500 USD. The price of an OEM ceramic disc brake set for Porsche is 14,949 USD, 21,895 USD or 29,000 USD if Brembo. And they have to go with expensive brake pads, specialized types.
That price is much more expensive than conventional cast iron disc brakes. For example, a Brembo steel brake set costs only one third of Brembo’s ceramic disc brakes; an AP Racing brake set costs only 1/4. That’s why some people recommend buying a Brembo steel disc brakes and putting away the PCCB ceramic disc brakes, when the car is sold, install it, and why on YouTube is full of videos Porsche car owners change the brakes carbon ceramic disc. One point to note is that carbon brakes are famous for being “fragile”. If the repairer makes a batch of robots, the car repair bill will add a significant amount.
The carbon brakes are lighter, look “cooler”, and are much more durable than cast-iron brakes on regular roads. They also did not produce any brake dust. According to a Washington State University document, the amount of copper in the brakes in a minute is enough to kill a salmon in the northwest Pacific. Another study by the American Ecological Association also showed similar results.
Therefore, when Wheels magazine asked Mr. Watson that carbon carbon disk brake was for someone, he replied: “Those are people who do not like washing cars. They don’t let brake dust build up, so that’s an advantage.
