The Aston Martin DBS Superleggera is a testament to British engineering, blending raw power with elegant design. Owners seeking to elevate their driving experience often explore avenues for enhanced performance and responsiveness. Carbon Ceramic Brakes (CCB), a technology derived from motorsport and aerospace, present a compelling upgrade path for discerning enthusiasts. While the DBS Superleggera may be equipped with CCBs from the factory, understanding the engineering benefits and maintenance profile of these advanced braking systems is crucial for maximizing long-term ownership value. This article delves into the key characteristics of CCB technology and its potential impact on the DBS Superleggera's braking performance.
Unsprung Weight vs Iron Rotors: What Changes With CCB?
Carbon Ceramic Brake rotors are typically up to 40-50% lighter than comparable cast iron rotors. This significant reduction in unsprung weight can contribute to improved handling dynamics and a more responsive feel. By decreasing the rotational inertia of the wheel assembly, the suspension system may react more quickly to road imperfections, potentially enhancing ride quality and cornering grip. It's weight your suspension no longer has to fight.
Heat Soak and Fade Resistance: Where C/SiC Rotors Differ
Standard iron brake rotors can experience performance degradation at elevated temperatures. Carbon Ceramic rotors, engineered from a composite silicon carbide (C/SiC) matrix, are designed to withstand substantially higher temperatures while maintaining a consistent friction coefficient. CCB rotors are designed to maintain a high friction coefficient at temperatures exceeding 900°C. This can contribute to improved braking consistency and reduced brake fade during demanding driving conditions.
Longevity Considerations: CCB Upgrade vs Conventional Brake Discs
While iron rotors typically require replacement depending on driving style and usage, carbon ceramic brake discs are engineered for extended service life. Under normal street-driving conditions, CCB rotors are designed to last up to 300,000 km, though actual lifespan depends heavily on driving habits, pad compounds, and environmental factors. This longevity can translate to lower long-term running costs for DBS Superleggera owners.
Brake Dust, Oxidation, and Daily Appearance: What to Expect
CCB technology can significantly reduce the corrosive metallic brake dust commonly associated with high-performance iron brake pads, which keeps the DBS Superleggera's wheels cleaner for longer. Furthermore, the C/SiC material is highly resistant to oxidation and road salts, which means reduced surface corrosion compared to traditional iron rotors. This helps maintain the pristine appearance of the braking system over time.
Floating Hat + C/SiC Matrix: Why This Design Is Used
Premium Carbon Ceramic Brakes often utilize a floating aluminum hat (or bell) system in conjunction with the C/SiC rotor. This design is engineered to manage thermal expansion effectively. The floating design allows the rotor to expand and contract independently of the hub, reducing thermal stresses and minimizing the risk of distortion or cracking. Advanced CCBs may utilize Continuous Long Carbon Fiber woven into a 3D matrix.
For Aston Martin DBS Superleggera owners seeking the pinnacle of braking technology, Carbon Ceramic Brakes offer a compelling set of engineering advantages. From reduced unsprung weight to exceptional thermal stability and extended service life, CCBs represent a significant upgrade. It is recommended that you consult with a qualified brake specialist to determine the optimal braking solution for your driving needs and ensure proper installation.
