BENTLEY GT GTC 3SD 2020 6.0 V12 Brake Kit

Bentley Continental GT / GTC W12 Brake Kit

Series: 3S / 3SD (Third Generation: 2018–2024+)

Engine: 6.0L W12 Twin-Turbo

The third-generation Bentley Continental utilizes two primary braking systems. For a 2020 W12 model, the car is likely equipped with the massive Iron Brake System as standard, or the optional Carbon Ceramic (CCB) system.

1. Standard Iron Brake System (420mm)

This is the most common fitment. It uses the largest iron discs ever fitted to a production car at the time of launch.

• Calipers: 10-piston monobloc front calipers (usually in Gloss Black or Red).

• Weight Note: A single front iron rotor weighs approximately 18–21 kg, which is why many owners eventually look into ceramic upgrades.

2. Carbon Ceramic Brake (CCB) System (440mm)

Recognizable by the massive Yellow (or sometimes Black) calipers with “Bentley Carbon Ceramic” branding.

• Performance: These virtually eliminate brake fade and reduce unsprung weight by nearly 30 kg across the vehicle, significantly improving ride quality over sharp bumps.

• Durability: Under normal road use, these discs are designed to last the lifetime of the vehicle, though the pads still require periodic replacement.

3. Key Service Requirements

• Stretch Bolts: The caliper mounting bolts are “one-time use” (torque-to-yield). If you are buying a “kit,” ensure it includes:

  • Front Bolts: N91147601 (x4)

• Brake Wear Sensors: The 3S uses electronic wear indicators on both the front and rear axles. These must be replaced if the “Brake Wear” light has appeared on the dashboard.

• EPB (Electronic Parking Brake): To replace the rear pads, the car must be put into “Service Mode” using a diagnostic tool (ODIS or VCDS) to retract the electronic calipers. Forcing them back manually will damage the internal motors.
