The Porsche 928, a grand tourer celebrated for its distinctive design and robust performance, represents a unique blend of luxury and sporting capability. For owners looking to further enhance their vehicle's braking system, upgrading to Carbon Ceramic Brakes (CCB) offers a compelling path. While the original iron brakes provide adequate stopping power for typical road use, CCB technology offers a range of engineering advantages that can contribute to an enhanced driving experience and potentially lower long-term ownership costs.
Unsprung Weight vs Iron Rotors: What Changes With CCB?
Carbon Ceramic Brake rotors are typically up to 40-50% lighter than their iron counterparts. This reduction in unsprung weight can contribute to improved suspension response, allowing the tires to maintain better contact with the road surface, particularly over uneven surfaces. This can result in improved steering feel and overall vehicle dynamics, enhancing the driving experience.
Heat Soak and Fade Resistance: Where C/SiC Rotors Differ
Standard iron brake rotors may experience performance degradation under sustained high temperatures, potentially leading to brake fade. CCB rotors, on the other hand, are engineered to maintain a high and consistent friction coefficient at temperatures exceeding 900°C. This enhanced thermal stability can contribute to improved braking consistency, especially during spirited driving or demanding braking scenarios.
Longevity Considerations: CCB Upgrade vs Conventional Brake Discs
Iron brake rotors typically require replacement within a range that varies based on driving style and conditions. Carbon Ceramic discs are designed to last up to 300,000 km under normal street-driving conditions. While the initial investment is higher, the extended service life of CCBs can potentially lead to lower long-term maintenance costs, particularly for vehicles driven regularly.
Brake Dust, Oxidation, and Daily Appearance: What to Expect
CCB technology can significantly reduce the corrosive brake dust commonly associated with high-performance iron pads, helping to keep your Porsche 928's wheels cleaner for longer. Additionally, the material is highly resistant to oxidation and road salts, which can reduce the surface corrosion often visible on traditional iron rotors, maintaining a cleaner, more refined appearance.
Floating Hat + C/SiC Matrix: Why This Design Is Used
Premium CCBs may utilize Continuous Long Carbon Fiber (T700 Grade) woven into a 3D matrix with Silicon Carbide, offering a more advanced structure compared to chopped-fiber alternatives. A floating aluminum hat system is typically employed to manage thermal expansion, allowing the rotor to expand and contract without inducing stress on the mounting points. This design can contribute to improved durability and performance.
Upgrading to Carbon Ceramic Brakes is a significant consideration for Porsche 928 enthusiasts focused on enhancing their driving experience and potentially reducing long-term maintenance. The improved thermal characteristics, reduced weight, and extended lifespan offer a compelling set of advantages. As with any performance modification, it is recommended to consult with a qualified brake specialist to ensure proper installation and compatibility with your vehicle.
