The brake discs and pads can attain an advantageous wear and contact pattern after traveling around 1,000 km (621 miles).
The M Carbon Ceramic Brake pads’ silicon carbide friction layer ensures that under typical (ideal) driving conditions, the brake pads will wear down relatively gradually. Since the silicon carbide friction layer is virtually wear-free, the M Carbon Ceramic Brake disc should endure for the whole life of the vehicle.
However, the brake discs may deteriorate more quickly on a racetrack. As previously noted, the M Carbon Ceramic Brake discs can burn up more quickly and experience oxidative wear if they are often heated to temperatures of 600 degrees or higher.

B. Sturdiness
Compared to standard iron rotors, ceramic composite brake discs are strong and extremely resistant to wear.
Unlike carbon ceramic rotors, which can last over 100,000 miles or even outlive your car, typical cast iron discs or iron rotors may only last up to 60,000 miles.
How long a carbon ceramic disc will survive, however, is not something that can be determined with absolute certainty. For instance, if you have a history of aggressive driving, your carbon ceramic brake disc may not last as long.
Does Your BMW Need Carbon Ceramic Brakes?
With the release of the current-generation M6 in 2012, BMW debuted carbon-ceramic brakes. The brakes were provided by Brembo, a company that works with many different automobile brands, including Pagani and Ferrari as well as the Mercedes F1 team.
Following the M6, BMW added carbon ceramic brakes to the M5, M3, and M4, and owners of these vehicles frequently question whether the added cost was worthwhile.
Carbon ceramic brakes, which were first used in the limited-edition Mercedes CL55 AMG F1 in 2001, may not stop your automobile as quickly as regular brakes, but they also don’t overheat. Ceramics are perfect for track enthusiasts since overheating increases braking distance, which is a major issue for them.
That is not to argue that the M vehicles’ basic brakes are in any way subpar. The X6 M and M2 didn’t have carbon ceramic brakes when we drove them at Circuit of The Americas and Laguna Seca, respectively, but we had no issues with brake fade. However, ceramics are still superior at keeping the braking fluid, pads, and discs from igniting, which is why BMW equips all of its vehicles with them at the US Performance Centers.
Additionally, carbon ceramic brakes reduce weight by 12.5 kg on the M3 and M4 and 19.4 kg on the M6. Additionally, lighter brakes result in less unsprung mass, which enhances acceleration and handling. Not to mention, you won’t have to worry about brake dust or disc degradation if you choose carbon ceramics.
All these advantages, though, come at a hefty cost. And we really do mean that. Because they can only be ordered with the larger, 19-inch wheels, carbon ceramic brakes for the M4 cost $8,150, plus an extra $1,200 for the rims. That brings the overall cost up to $9,350, which is more than the price of a brand-new E36 M3. Similar to the M5, the M5’s carbon ceramic setup costs $10,550.
Additionally, going to the workshop to replace the ceramic brakes will cost more money than traveling to Bangkok. You could counter that ceramics only last as long as cars do under typical driving conditions. Regular track users will inform you that ceramic brakes are not indestructible, despite not wearing out as quickly as conventional brakes.
The lack of pedal feel at low speeds and when the brakes are running cold can also be a problem, as can squeaking.
Should you then purchase them? only if you don’t care about the price. They do, after all, run better, last longer, and look awesome, especially with the larger rims and BMW’s distinctive golden calipers. Additionally, you might boast that you employ brakes identical to those used by racecars.
How frequently should carbon ceramic brakes be replaced?
A automobile with carbon ceramic brakes only needs ordinary (and affordable) brake pad replacements up until it has driven roughly 100,000 miles before needing new rotors. Most steel-brake cars require new rotors every few years.
Are carbon-ceramic brakes more rapid to stop?
Because carbon-ceramic discs have a larger friction coefficient than cast iron discs, they can be stopped more quickly. The car slows down before one with a conventional braking system because the increased friction coefficient produced by the carbon reduces the braking activation time.
Do ceramic brakes wear out?
Because ceramic brake pads are more pricey, they are regarded as premium and are typically found in luxury vehicles.
They are pricey, but their longevity more than makes up for the high cost. Additionally, if maintained properly, they can last you up to 75,000 kilometers. Of course, how you drive has a big impact on how long they last. Nevertheless, compared to the alternatives, these brakes last the longest overall.
Carbon-ceramic brake pads are excellent for low-performance vehicles, but they can easily last up to 80,000 miles before they need to be replaced. This is their main drawback. Because of their extended lifespan and high initial cost, they are more than worth the investment even if they are expensive.
BMW use ceramic brake pads, right?
M Performance Brakes for BMW If you operate one of these potent thrill vehicles, you can fit it with either the base set of M brakes, the BMW M Compound Brakes, or the optional Carbon Ceramic Brakes.
Brakes made of carbon-ceramic overheat?
DOWNTOWN, Mich.
In 2012, BMW debuted carbon-ceramic brakes with the M6. A small number of high-end and luxurious vehicles, including Mercedes, Porsche, Alfa-Romeo, Ferrari, and Pagani, have the Brembo brakes as an option. There is a meager take rate.
According to various reports and my own experience driving some of these automobiles, ceramic brakes have the same braking power as iron brakes, despite the fact that experts claim that ceramic brakes have one benefit over iron brakes in that they do not overheat. As a result, the stopping distance on the track is reduced. But those who drive their fast cars on tracks are a very particular market segment.
Ceramics also reduce weight, but at a significant cost. On the BMW M6, ceramic brakes weigh 19.4 kg less than iron brakes, and the M3 and M4 both weigh 12.4 kg less. With the ceramics, there is also no brake dust. However, the M4’s ceramics cost $8,150 in addition to an extra $1,200 for custom rims. On the M5, ceramics cost $10,550.
Alfa-Romeo has also joined the fray, but the take rate seems minimal. Recent Giulia QF testing by Car and Driver revealed that the iron brakes had “stunning” stopping power and that there was no need to choose the more expensive ceramic brakes.
A recent revelation by a Porsche technical advisor, who claimed that the company’s ceramic brakes were not necessarily suitable for track use as has been promised, further complicated the situation.
When the 992-generation Porsche 911 was recently launched, I spoke with Which Car about it.
“Yes, if you use your brakes harshly, ceramic discs can deteriorate. The carbon fibers in the disc will deteriorate with increased heat, hence iron discs are always advised on club days “said Watson.
The debate goes on as a result. Only one thing is certain. People who purchase luxury race vehicles frequently have sufficient funds, so an additional $10,000–12,000 won’t make much of a difference to them. And for many people, ceramics are just another cosmetic addition that will improve their mood even if they don’t improve performance.
Is purchasing ceramic brakes worthwhile?
Ceramic plates and ceramics are formed of a type of ceramic that is quite similar to the substance used to make ceramic brake pads. However, ceramic brake pad material is far more dense and robust. Fine copper fibers are also included into ceramic brake pads to aid improve their heat conductivity and friction.
Ceramic brake pads have gained popularity steadily since its creation in the middle of the 1980s for a number of reasons:
- Noise-Level: When the brakes are used, ceramic brake pads make very little additional noise.
- Ceramic brake pads tend to produce less dust and other debris as they deteriorate than organic brake pads do.
- Temperature & Driving Circumstances: Ceramic brake pads can be more dependable in a wider variety of temperatures and driving conditions when compared to organic brake pads.
However, there are significant drawbacks to ceramic brake pads. First and foremost, their price: Compared to other types of brake pads, ceramic brake pads are often the most expensive due to greater manufacturing costs. Additionally, more of the heat produced by braking will pass through the brake pads and into the remainder of the braking system because copper and ceramic cannot absorb as much heat as other types of materials. Other braking parts may see increased wear and tear as a result. Last but not least, ceramic brake pads are widely regarded as the best option for arduous driving conditions. If you have to choose between semi-metallic and ceramic brake pads because of the impending race or really cold conditions, you should choose metallic.
Can carbon-ceramic brakes be warped?
No Warping Carbon Ceramic Rotors These brakes are significantly less likely to distort than brakes made of steel because of how much heat they can withstand.
What causes squeaking in carbon ceramic brakes?
When driving a sports car or taking a city bus, squealing brakes are both inconvenient. Even though it is annoying, Porsche’s engineers want you to know that you shouldn’t be concerned.
The German corporation has created a brief but pretty in-depth film on the topic, most likely so that dealerships can give it to customers or show it to them to help reduce complaints about the problem. In essence, the narrator presents two options: either accept it because Porsche brakes are the best in the world, or constantly accelerate.
Cold brakes can squeal at low speeds in any car, it’s a fact. Without frequent stops from normal cruising speeds—or, if they are carbon-ceramic brakes, without forceful pedal applications at considerably higher speeds—the pads and the rotors won’t reach operational temperature.
The video’s argument is supported by graphs, charts, 3D representations, and other nerdy materials. It’s true that a new 911 makes more noise when moving around town than your neighbor’s 2006 Toyota Corolla. The truth about performance brakes installed in high-end cars is that they typically forego acoustic refinement and long life in favor of more powerful and responsive stopping. We are willing to make this trade-off.
