CCB vs CCM: Understanding the Difference
While both CCB and CCM rotors use carbon-silicon carbide composites, the key difference lies in the surface treatment. Our CCB rotors feature a proprietary Silicon Carbide coating that provides significant advantages over traditional CCM (Carbon Ceramic Matrix) designs.

CCB (Carbon Ceramic Brake)
CCB rotors feature a dense Silicon Carbide (SiC) coating applied to the friction surface. This coating creates a protective barrier that shields the underlying C/SiC matrix, dramatically improving wear resistance and extending rotor life.

CCM (Carbon Ceramic Matrix)
Traditional CCM rotors (such as OEM PCCB) expose the raw C/SiC matrix directly to the friction surface. While still high-performance, this design is more susceptible to surface oxidation and requires more specific pad compounds.
| Feature | CCM (Traditional) | CCB (SiC Coated) |
|---|---|---|
| Surface Treatment | None (Exposed Matrix) | Silicon Carbide Coating |
| Oxidation Resistance | Moderate | Excellent (Coating Protection) |
| Wear Rate | 0.02-0.04 mm/1000km | 0.008-0.015 mm/1000km |
| Pad Compatibility | CCM-Specific Only | Wider Range (CCB-Optimized) |
| Expected Lifespan | 150,000 - 200,000 km | 250,000 - 300,000 km |
| Cold Bite Performance | Good | Excellent |
| Surface Consistency | Variable Over Time | Stable Throughout Life |
Manufacturing Process
A 6-stage precision manufacturing process spanning over 20 days
Fiber Preforming
Room TempHigh-purity carbon fibers (continuous or chopped, depending on series) are combined with phenolic resin binder and compressed into the initial disc shape under high pressure. This creates the foundational structure for the rotor.
Carbonization
900°CThe preform undergoes pyrolysis in an inert atmosphere at 900°C. This process converts the phenolic resin into pure carbon, creating a porous Carbon-Carbon (C/C) skeleton with controlled porosity for the next infiltration step.
Silicon Infiltration (LSI)
1600°CLiquid Silicon Infiltration (LSI) is performed at 1600°C in a high-vacuum environment. Molten silicon is drawn into the porous structure through capillary action, where it reacts with the carbon to form Silicon Carbide (SiC), creating the C/SiC composite matrix.
Precision Machining
Room TempDiamond-tipped tools machine the rotor to exact tolerances (±0.05mm). Ventilation channels are drilled with precision CNC equipment to optimize cooling airflow. Surface flatness is verified to within 0.02mm across the friction face.
SiC Surface Coating
1200°CThis is the key CCB differentiator. A dense Silicon Carbide coating is applied to the friction surfaces using Chemical Vapor Deposition (CVD) or reactive bonding. This 50-100µm thick layer provides exceptional wear resistance and protects the underlying matrix from oxidation.
Quality Inspection
Room TempEvery rotor undergoes comprehensive testing: X-ray inspection for internal voids, dynamic balancing to G6.3 standard, dimensional verification, surface hardness testing, and friction coefficient validation on our in-house dynamometer.
The SiC Coating Advantage
Our proprietary Silicon Carbide surface coating is what sets CCB rotors apart from traditional CCM designs. Applied at 1200°C, this 50-100 micrometer thick ceramic layer fundamentally transforms the rotor's performance characteristics.
- Creates a uniform, ultra-hard friction surface (Hardness: 2500+ HV)
- Prevents oxidation of the underlying carbon matrix at high temperatures
- Reduces wear rate by up to 60% compared to uncoated CCM rotors
- Provides consistent friction coefficient throughout the rotor's entire lifespan
- Improves cold bite performance for better everyday drivability
- Enables compatibility with a wider range of brake pad compounds
