BENTLEY GT BRAKE SYSTEM BRAKE CERAMIC CERAMIC BREMBO

Bentley’s Carbon Silicon Carbide (CSiC) brake system is one of the most powerful ever fitted to a production car. Primarily manufactured by Brembo (calipers) and SGL Carbon (discs), this system is designed to provide fade-free stopping power for a vehicle that can exceed \text{ mph}$.

1. Technical Specifications (3S / New Model)

The current generation Bentley Continental GT (2019–Present) features the world’s largest front brake discs.

• Front Discs: $440 \text{ mm} \times 40 \text{ mm}$ (Carbon Ceramic).

• Front Calipers: 10-Piston Brembo Monobloc (Massive aluminum units).

• Rear Discs: $410 \text{ mm} \times 32 \text{ mm}$ (Carbon Ceramic).

• Rear Calipers: 4-Piston Brembo (with integrated electronic parking brake).

• Weight Saving: Total unsprung weight reduction of approximately $33 \text{ kg}$ ($73 \text{ lbs}$) compared to the standard iron system.

3. Why Ceramic? (CSiC vs. Steel)

• Fade Resistance: Steel brakes lose efficiency as they heat up (brake fade). Ceramics can operate at temperatures exceeding $1000^\circ\text{C}$ without losing “bite.”

• Durability: Under normal road use, ceramic discs can last the entire lifetime of the vehicle ($100,000\text{+ miles}$), whereas steel discs require replacement every $30,000$ miles.

• Dust: Ceramic brakes produce almost zero visible brake dust, keeping your Mulliner wheels clean.

4. Maintenance & Risks

• Chipping: The most common way these discs “fail” is physical damage. If a mechanic accidentally bangs a wheel against the disc during a tire change, the ceramic can chip. Once chipped, the disc is structurally compromised and cannot be resurfaced; it must be replaced.

• Brake Squeal: Carbon ceramics are notorious for squealing when cold. This is a characteristic of the material, not a defect.

• Replacement Cost: In 2026, a single front ceramic disc typically costs between $5,000 and $7,500 USD.
