Carbon Ceramic Brake Discs

St s next generation carbon ceramic brake discs are designed for performance driving and the track day enthusiast.

Carbon ceramic brake discs.

After two months we can now reassure that the cycle time of appx. Rather than cast iron or steel carbon ceramic brake discs are made from a composite material. Porsche s composite ceramic brakes pccb are siliconized carbon fiber with high temperature capability a 50 weight reduction over iron discs hence reducing the vehicle s unsprung weight a significant reduction in dust generation substantially extended maintenance. C sic utilises silicon carbide with carbon fibre and this compound is thought to be more durable than pure carbon carbon.

While conventional carbon ceramic brake discs use discontinuous chopped carbon fibre st interweaves continuous carbon fibre to form a 3d matrix producing a stronger and more durable. The 390 mm carbon ceramic discs at the front are coupled to 6 piston calipers with a 143 cm2 pad while the 360 mm carbon ceramic discs on the rear are coupled to 4 piston calipers with a 77 cm2 pad. The brake system is completed with brembo ccm discs that ensure a weight reduction of 50 compared to cast iron discs. Composite brakes can withstand temperatures that would damage steel discs.

These brake pads are made from ceramic very similar to the type of ceramic used to make pottery and plates but is denser and a lot more durable. Carbon fibre reinforced silicon carbide c sic is a development of pure carbon carbon and can be used in automotive applications such as components of brake systems on high performance road cars namely the brake disc and brake pads. In june 2019 rebrake bought the technology as well as worldwide marketing rights and took over the production. Another option for brake pads are ceramic brake pads.

This led to the development of carbon ceramic brakes combining most of the benefits of all carbon brakes with the added durability provided by ceramics. The introduction of silica carbide increased the oxidisation and thermal shock resistance making the brake discs last longer and better handle a wider range of temperatures. The company that owned the patent for carbon ceramic brake discs refurbishment and produced for us has turned out to be an unreliable partner many times. Many drivers have been disappointed to be told their carbon ceramic discs need replacing after only a few track sessions and a replacement set of discs can cost over 10 000.
