Carbon Ceramic Rotors: Many Strengths but High Price

Carbon Ceramic Rotors Boast Many Advantages – and a High Price Tag

Would you spend $8,000 to $12,000 for an optional brake package on your next vehicle?

What if I told you they would never fade, would improve gas mileage and maybe need a change every 180,000 miles? Ceramic composite or carbon ceramic brake rotors and pads offer these advantages – and more.

While it may seem like these systems are untouchable like some supermodels, this expensive option on some high performance vehicles could be the brake of the future – if the cost comes down.

Ceramic composite rotors are extremely durable. In fact, manufacturers claim that they’ll never need replacement – at least with “normal” driving. They’re also resistant to the kind of distortions and wear that lead to pedal pulsation – merely an annoyance in the “real world,” but a noticeable performance issue on the track.

The brake discs are formed from a specially treated carbon-fiber compound that is silicated in a high-vacuum process at higher temperatures than any stop could produce. Not only are the resulting discs much harder than standard discs, they are more resistant to heat. The process used to produce the discs for CCB is complex, time-consuming and costly when compared to cast iron.

The carbon fibers are blended with a resin of carbon and silicon. The mixture is pressed into a mold to create the basic disc shape, including its internal cooling vents. Using heat up to 3,000º F, the resin is converted to silicon carbide, a material nearly as hard as diamond. This is the “ceramic” in “carbon ceramic.” If you tried to machine these rotors, you would need diamond tipped bits in your brake lathe.

The low thermal expansion of the brake discs prevents deformation under heavy braking. Furthermore, the ceramic brake discs are totally resistant to corrosion and offer more favorable noise-damping properties.

Advantages
Because of their exceptional perfor­mance in extreme conditions, ceramic composite brakes were developed for use in high-level motorsports competition. Porsche was the first automaker to apply them for road use, with Porsche Ceramic Composite Brakes included as standard equipment in the Porsche GT2 and Carrera GT and as an option in most other models.

Ceramic composite brake discs provide a 50% weight savings compared to conventional metal discs. This reduces unsprung weight, enhances shock absorber response and vehicle handling, and also improves fuel efficiency and contributes to reduced emissions.

Ceramic composite brake discs have an extremely hard surface that provides consistent frictional values throughout the deceleration process, even in braking from extremely high speeds and at high operating temperatures, such as those generated from repeated braking.

But the system also provides benefits in low-speed situations. In the event of an emergency stop, the technology does not require heavy pedal forces or outside technological boosting assistance to achieve maximum and immediate stopping force.

With cross-drilled discs and pads that are resistant to water absorption, the ceramic composite brakes provide superior response in wet conditions, as well as dry. Because of their hard surface and immunity to salt corrosion, Porsche Ceramic Composite Brakes have an extre­mely long operating life.

Service Life
Porsche Ceramic Composite Brakes have been on the market for almost 10 years. There have been no recalls or lawsuits. With some complaints on low speed noise, Porsche’s advice is to warm them up.

The only real complaints with the ceramic disc have come from weekend racers who experienced cracked discs due to extreme abuse. Porsche’s advice  is to check for cracks before they head out to the track. With the replacement costs of four discs and pads reaching more than $20,000, many are switching to cast iron rotors and semi-metallic pads.
