Carbon ceramic disk brakes are brake rotors made from a carbon-fiber-reinforced silicon carbide ceramic matrix composite. TEI’s TCCB and TCCB-R rotors are designed for consistent braking during sustained heavy use, with application-specific construction, sizing, and pad requirements.
What are carbon ceramic disk brakes?
Carbon ceramic disk brakes use a carbon-fiber-reinforced silicon carbide ceramic matrix composite, commonly abbreviated as C/SiC. TEI offers two carbon-ceramic rotor architectures: TCCB, a one-piece molded short-fiber rotor, and TCCB-R, a continuous carbon-fiber long-fiber rotor.
The braking surface is protected by a silicon carbide friction coating. TEI’s carbon-ceramic collection describes these discs as suited to lower unsprung weight and consistent stopping power under sustained heavy braking, with no fade. As with any brake upgrade, the tyre and pad-rotor friction pair determine stopping distance. Brake hardware primarily contributes to pedal feel, consistency, and heat capacity rather than independently shortening stopping distance.
TEI TCCB and TCCB-R carbon ceramic rotor options
The two TEI carbon ceramic disk brake options share the C/SiC material family but use different manufacturing approaches. The right choice depends on whether you want a practical molded rotor or custom sizing with continuous-fiber construction.
| Feature | TCCB Carbon Fiber Ceramic Rotor | TCCB-R Long-Fiber Carbon Fiber Ceramic Rotor |
|---|---|---|
| Fiber construction | One-piece molded short carbon fibers | Continuous carbon-fiber layup |
| Material | Carbon-fiber-reinforced silicon carbide ceramic matrix composite | Carbon-fiber-reinforced silicon carbide ceramic matrix composite |
| Silicon carbide coating | 1.1 mm friction coating | 0.8 mm friction coating |
| Diameter range | 355 mm to 440 mm | 355 mm to 440 mm |
| Manufacturing role | Volume-production process for stable, consistent production | More complex, higher-cost process for custom sizing and continuous-fiber strength |
TCCB is the practical choice that balances performance and practicality. Its molded short-fiber construction is identified as the architecture used for OEM high-performance braking on supercars and high-end passenger vehicles. TCCB-R is adapted from a long-fiber process originally developed for aerospace, ultra-high-speed rail, and extreme-performance applications.
Carbon ceramic disk brake coating and normal surface crackle
Fine hairline cracks in the SiC-coated face are a normal characteristic of every carbon-ceramic disc. During manufacturing, the coating and the disc body contract at different rates. The resulting crackle pattern releases internal stress; it is not, by itself, evidence that the rotor is defective.
The outer edge and inner bore are intentionally left uncoated. This design helps prevent edge chipping during assembly and transport. The coated friction face and the uncoated areas therefore have different visible appearances, which is expected for these rotors.
For more practical information about carbon-ceramic ownership topics, read TEI’s guide to carbon ceramic rotor brake dust and maintenance. Product selection should also account for the vehicle, wheel package, rotor diameter, and the rest of the brake system.
Pad compatibility is essential
TEI carbon-ceramic discs must run TEI CS1 or CS2 compound pads only. These compounds are engineered specifically for the SiC-coated CCB surface. M1, M2, R1, and R2 compounds must not be used on carbon-ceramic discs.
This requirement makes pad selection part of the rotor specification, not an optional preference. Before ordering replacement pads, confirm that the compound is CS1 or CS2 and that the pad shape matches the installed caliper. TEI’s carbon ceramic disc collection is the relevant starting point for reviewing the available rotor products.
Carbon-ceramic rotors do not automatically mean that every component in a brake kit is included. The TCCB and TCCB-R product listings are for the carbon-ceramic rotor only. Rotor hats, brackets, pads, and brake lines are not included. Pads are sold separately. If you are assessing a complete system, the guide to what brake kits include can help clarify component scope.
Carbon ceramic rotors versus high-carbon alloy discs
Carbon-ceramic rotors and high-carbon alloy discs are different product categories. TEI’s G3500 high-carbon alloy brake discs use an alloy containing 3.85% carbon and have a heat-resistance rating of up to 600°C. They use blade-fang slots cut through to the disc edge for dust evacuation and dual-layer construction that forms continuous cooling channels between the friction faces.
G3500 discs are available in diameters from 285 mm to 405 mm and are sold in pairs. Their diameter is matched to the vehicle and wheel package. By contrast, TCCB and TCCB-R are C/SiC carbon-ceramic rotors available in diameters from 355 mm to 440 mm. The two types should therefore be selected according to the intended material system, fitment, and compatible brake components rather than treated as interchangeable versions of the same rotor.
For broader rotor-selection context, see TEI’s article on carbon ceramic versus steel rotors. The comparison should remain specific to the vehicle and use case because rotor material, dimensions, pad compound, and system compatibility all matter.
Fitment and ordering considerations
Rotor diameter is only one part of a correct carbon ceramic disk brake installation. Confirm the vehicle application, wheel package, rotor dimensions, caliper relationship, and the required pad compound before ordering. TEI TCCB and TCCB-R rotors are offered from 355 mm to 440 mm, while TCCB-R can be custom-made to OEM specifications within that diameter range.
The TCCB product listing states that an existing TEI brake kit’s hat and brackets are the matching pair for these rotors. This does not mean that hats and brackets are included with a rotor-only listing. If your current system is not a matching TEI application, use the brake kit fitment technical checklist and confirm the configuration before purchase.
A complete brake-system decision should also account for pedal feel, heat capacity, and consistency. These are the areas where brake hardware matters. Stopping distance still depends on the tyres and the pad-rotor friction pair, so a carbon-ceramic rotor should be specified as part of a compatible braking system rather than viewed as an isolated stopping-distance solution.
Frequently asked questions
What are carbon ceramic disk brakes?
Carbon ceramic disk brakes use carbon-fiber-reinforced silicon carbide ceramic matrix composite rotors. TEI’s TCCB uses molded short carbon fibers, while TCCB-R uses continuous carbon-fiber layup. Both use a silicon carbide friction coating and are available in diameters from 355 mm to 440 mm.
Are hairline cracks on a carbon ceramic rotor normal?
Yes. Fine hairline cracks in the SiC-coated surface are a normal characteristic of every carbon-ceramic disc. The coating and disc body contract at different rates during manufacturing, creating a crackle pattern that releases internal stress. The outer edge and inner bore are intentionally left uncoated to help prevent edge chipping.
Which brake pads can be used with TEI carbon ceramic rotors?
TEI carbon-ceramic discs must use TEI CS1 or CS2 compound pads. These compounds are engineered for the SiC-coated CCB surface. M1, M2, R1, and R2 compounds must not be used on carbon-ceramic discs. Pads are sold separately from the rotor-only product listings.
Do TEI carbon ceramic rotor listings include hats and brake pads?
No. The TCCB and TCCB-R listings are for the carbon-ceramic rotor only. Rotor hats, brackets, pads, and brake lines are not included. For TCCB, the hat and brackets from an existing TEI brake kit are the matching pair. Pads must be purchased separately and must use CS1 or CS2 compounds.
