The Aston Martin Vanquish (VH) is celebrated for its blend of performance and elegance. While the factory braking system is capable, enthusiasts often explore options to enhance its performance and longevity. Carbon Ceramic Brakes (CCB) present a compelling upgrade path, offering unique engineering characteristics that can contribute to an enhanced driving experience. This article explores the core engineering differences between standard iron brakes and CCB technology, focusing on the benefits for the Vanquish's performance profile.
Unsprung Weight vs Iron Rotors: What Changes With CCB?
CCB rotors are typically up to 40-50% lighter than comparable cast iron rotors. This significant reduction in unsprung weight can contribute to improved suspension response, allowing the wheels to more closely follow road contours. The reduction in rotational inertia can also improve acceleration and deceleration feel, enhancing the overall responsiveness of the Aston Martin Vanquish.
Heat Soak and Fade Resistance: Where C/SiC Rotors Differ
Standard iron brake rotors can experience performance degradation due to heat soak under demanding conditions, potentially leading to brake fade. CCB rotors, engineered with Composite Silicon Carbide (C/SiC), are designed to maintain a high and consistent friction coefficient at temperatures exceeding 900°C. This characteristic can contribute to improved braking consistency and pedal feel, particularly during spirited driving or track use.
Longevity Considerations: CCB Upgrade vs Conventional Brake Discs
Cast iron rotors on the Aston Martin Vanquish may require replacement depending on driving style and environmental conditions. Carbon Ceramic discs, however, are designed for extended service life. Under normal street-driving conditions, they are designed to last up to 300,000 km. This longevity can translate to reduced long-term maintenance costs, making them a viable option for owners prioritizing long-term value.
Brake Dust, Oxidation, and Daily Appearance: What to Expect
CCB technology can significantly reduce the corrosive brake dust commonly associated with high-performance iron brake pads. This helps keep the Vanquish's wheels cleaner and reduces the need for frequent cleaning. Furthermore, the material is highly resistant to oxidation and road salts, which can reduce the surface corrosion that may be visible on traditional iron rotors, preserving the aesthetic appeal of the braking system.
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. This advanced structure offers enhanced strength and thermal management properties compared to chopped-fiber alternatives. A floating aluminum hat (bell) system is typically employed to manage thermal expansion, allowing the rotor to expand and contract without inducing stress on the mounting points. This design is engineered to enhance durability and performance.
For Aston Martin Vanquish owners seeking to elevate their driving experience, upgrading to Carbon Ceramic Brakes is a worthwhile consideration. The reduced weight, enhanced thermal stability, and potential for extended longevity represent a compelling set of engineering advantages. It is recommended to consult with a qualified brake specialist to determine the optimal brake pad compound and installation procedures for your specific driving needs.
