Bentley Continental GT GTC Ceramic Brake Disc Brake Caliper NEW
Bentley’s Carbon Silicon Carbide (CSiC) brake system remains the world standard for stopping power in the luxury GT segment. For the latest generation (2019–2026), these components are notably larger and more advanced than the previous “3W” series.
1. Key Component Identification (Gen 3 / 2024–2026)
The front discs on the current Continental GT/GTC are the largest ever fitted to a production car at 440mm.
| Component | Side | Part Number (Base) | |
| Front Ceramic Disc | Left | 3SA615301B | |
| Front Ceramic Disc | Right | 3SA615302B | |
| 10-Piston Caliper | Left | 3SA615123H (Black) | |
| 10-Piston Caliper | Right | 3SA615124H (Black) | |
| Brake Pad Set | Axle | 3SA698151D |
2. Caliper Color Options
Bentley offers several factory finishes for the ceramic Brembo calipers. The suffix of the part number changes based on the color:
-
Black: The standard “stealth” look, often paired with the Blackline Specification.
-
Red: The most common choice for Speed models.
-
Yellow/Green/Blue: Custom Mulliner finishes are available (e.g., 3SA615123J for Red variants).
3. Why Buy “NEW” vs. Used?
When sourcing carbon ceramics, the “New” designation is critical for two reasons:
-
Chipping Risk: Ceramic discs are brittle. A used disc may have microscopic chips on the edge from a poor wheel change. These chips can lead to total disc failure under high thermal load.
-
Surface Oxidation: Unlike steel, ceramic discs don’t “rust,” but they can oxidize and lose mass if driven hard on a track. New discs come with a factory-guaranteed weight; once a disc loses a certain percentage of its original mass, it is legally “dead” regardless of how thick it looks.
4. Technical Warning: The “Puck” System
The latest 10-piston calipers use a specialized “puck” system behind the pads to distribute pressure across the massive 440mm surface.
-
Installation: When installing new pads, these ceramic pucks must be inspected for cracks.
-
Bedding-In: New carbon ceramic discs and pads require a specific “burnishing” process (typically 20–30 stops from 60mph to 20mph) to transfer a layer of pad material onto the disc. Failing to do this can cause permanent brake shudder.
