Mercedes AMG S63 223 / GT63 X290 Ceramic / Ceramic Brake System

Mercedes-AMG S63 (W223) & GT 63 (X290) | Gold Calipers

The AMG Carbon Ceramic (CCB) system represents the peak of braking performance for heavy, high-output Mercedes-AMG vehicles. Identified by their signature Bronze/Gold calipers, these systems offer a 40% reduction in unsprung weight compared to steel, virtually zero brake fade, and an extreme service life (up to 300,000 km under normal use).  Mercedes AMG S63 223 / GT63 X290 Ceramic / Ceramic Brake System

Technical Comparison: W223 vs. X290 Systems

While both use the same material technology, the hardware is tailored to the specific weight and aero requirements of the S-Class (luxury/high-speed) versus the GT 4-Door (motorsport/track-focused).

Common Maintenance & Retrofit Data

 Essential Component Part Numbers (Sample):

• W223 S63 Front CCB Discs: A2234211100 (Left) / A2234211200 (Right)

• X290 GT63 Front CCB Discs: A2904214100 (Left) / A2904214200 (Right)

• Universal Wear Sensor: A1715400617 (Common for many AMG CCB applications)

• CCB Brake Fluid: DOT 4 Plus (A0009890807)

Retrofitting CCB to a Non-CCB AMG

Converting from standard red/silver steel brakes to gold carbon ceramics is possible but involves more than just rotors and calipers:

1. The Suspension Factor: On the W223 S63, the steering knuckles (spindles) are often different for CCB cars to accommodate the larger caliper offset.

2. Master Cylinder: CCB systems move a different volume of fluid; some retrofits require the high-output master cylinder and booster to avoid a “mushy” pedal.

3. Software Coding: The ESP and ABS modules must be reprogrammed. CCB rotors generate different friction levels at different temperatures; the car needs to know it is using ceramic discs to manage emergency braking and pad-drying cycles correctly.

4. The “Chip” Warning: Carbon ceramic rotors are incredibly hard but brittle. A single rock chip or a mechanic hitting the rotor with a wheel during a tire change can ruin a $5,000 disc instantly.
