Aston Martin Vanquish Ceramic Brake Disc Front CD332C026AA

part number CD33-2C026-AA (or the updated CD33-2C026-CA) identifies a Carbon Ceramic Matrix (CCM) brake disc for the second-generation Aston Martin Vanquish (2012–2018).

Correction: While your query asks for a “Front” disc, this specific part number (CD33-2C026-AA) actually refers to the Rear Brake Disc ($360 \times 32$ mm). The corresponding Front Disc part number is typically CD33-1125-CA ($398 \times 36$ mm).

1. Technical Specifications

• Material: Carbon Ceramic Matrix (CCM) manufactured by Brembo.

   

• Dimensions: * Front (CD33-1125-CA): $398$ mm diameter, $36$ mm thickness.

  • Rear (CD33-2C026-AA): $360$ mm diameter, $32$ mm thickness.

• Benefit: Reduces unsprung weight by nearly 50% (approx. 12kg/26lbs per axle) compared to cast iron, virtually eliminating brake fade.

   

2. Pricing & Market Value (2026)

Carbon ceramic discs are among the most expensive consumable parts on the vehicle.

3. Critical Maintenance: The “Weight” Rule

Unlike steel discs, you cannot measure CCM wear by thickness alone.

• The Weight Test: Every CCM disc has a minimum weight (in grams) laser-etched onto the aluminum center bell. As the carbon fibers oxidize over time (due to track use or high heat), the disc loses density. If the disc falls below this weight, it must be replaced, even if it looks perfect.

• Surface Chips: Ceramic discs are extremely brittle. If a technician accidentally bangs a wheel rim against the edge of the disc during a tire change, the resulting chip can cause a structural failure, requiring immediate replacement.

4. Replacement Parts & Kits

• Front Pads: CD33-2D007-AA (Designed specifically for the CCM surface).

• Disc & Pad Set (Front): CD33-28-10138 (The full factory-ordered axle kit).

   

• Caliper Mounting Bolts: These are one-time-use stretch bolts. Do not reuse the old ones when swapping discs.
