The Aston Martin DBS, with its lineage of performance and grand touring capability, represents a pinnacle of automotive engineering. For discerning owners seeking to refine the driving experience, upgrading to Carbon Ceramic Brakes (CCB) presents a compelling opportunity. While the factory braking system is undoubtedly capable, CCB technology offers distinct engineering advantages, particularly in terms of weight reduction and thermal management, that can further elevate the DBS's performance characteristics. This article explores those advantages.
Could Lighter CCB Rotors Improve Steering Feel in a Performance Sports Car?
Carbon Ceramic Brake rotors are typically designed to be significantly lighter than their cast iron counterparts, often by as much as 40-50%. In the Aston Martin DBS, this reduction in unsprung rotational mass at each wheel can contribute to noticeably improved steering feel and responsiveness. Less weight for the suspension to manage can translate to a more agile and connected driving experience, especially during corner entry and transitions.
Why Does Thermal Stability Matter for Performance Brake Consistency?
During spirited driving or track use, standard iron brake discs can experience significant temperature increases, potentially leading to brake fade and inconsistent performance. CCB rotors, in contrast, 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 and pedal feel, even under demanding conditions, allowing the driver to maintain confidence.
How Long Can Carbon Ceramic Discs Last in Normal Street Use?
While the lifespan of any brake rotor depends on driving habits and environmental factors, Carbon Ceramic discs are designed for exceptional longevity. Under normal street-driving conditions, CCB rotors can potentially last up to 300,000 km. This extended service life, compared to the more frequent replacements typically required for iron rotors, can represent a significant long-term value proposition for DBS owners.
Do Carbon Ceramic Brakes Help Keep Wheels Cleaner Over Time?
One of the less-discussed but appreciated benefits of CCB technology is the virtual elimination of corrosive brake dust. Unlike traditional iron brake pads, which produce a significant amount of metallic dust, CCB pads generate minimal dust. This helps keep the DBS's alloy wheels cleaner for longer, reducing the need for frequent cleaning and preserving their aesthetic appeal. Furthermore, the material is highly resistant to oxidation.
How Does Fiber Architecture Influence CCB Heat and Stress Behavior?
Premium Carbon Ceramic Brake rotors may utilize Continuous Long Carbon Fiber (T700 Grade) woven into a 3D matrix with Silicon Carbide. This advanced construction technique offers superior strength and thermal conductivity compared to chopped-fiber alternatives. Furthermore, a floating aluminum hat system is typically employed to manage thermal expansion, helping to prevent stress cracking and maintain rotor integrity under extreme heat.
For the Aston Martin DBS owner seeking the ultimate in braking performance and driving refinement, upgrading to Carbon Ceramic Brakes is a worthwhile consideration. The reduction in unsprung weight, enhanced thermal stability, and extended service life can contribute to a more engaging and rewarding driving experience. It is highly recommended to consult with a qualified brake specialist to determine the optimal CCB configuration for your specific driving needs and vehicle setup.
