BENTLEY CONTINENTAL GT 18-24 3S 3SD Front Brake Caliper Set

Genuine Bentley Continental GT Front Brake Caliper Set

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

The third-generation Bentley Continental GT (chassis code 3S) features some of the most powerful braking systems ever fitted to a production car. The calipers for this generation are significantly different from the previous 3W series, moving to a massive 10-piston setup for both the standard Iron and optional Carbon Ceramic systems.

1. Standard Iron Brake System (420mm)

Standard on the V8 and W12 models, these use a high-performance 10-piston fixed caliper designed by Brembo.

• Left Front Caliper: 3S0615107

• Right Front Caliper: 3S0615108

• Common Colors: Gloss Black (Standard), Red (Optional/S-models).

• Brake Disc Size: 420mm x 40mm.

2. Carbon Ceramic Brake System (440mm)

Often found on the GT Speed or as a high-cost option on standard models. This system features the largest front brake discs currently in production for a passenger car.

• Left Front Caliper: 3S0615107C (or suffix revision)

• Right Front Caliper: 3S0615108C

• Common Colors: Yellow (Classic CCB), Black (Stealth).

• Brake Disc Size: 440mm x 40mm.

3. Key Technical Features

• 10-Piston Architecture: Unlike the older 6-piston or 8-piston setups, the 3S calipers use 10 pistons of varying diameters to provide perfectly even pressure across the massive brake pads.

• Shared Architecture: While these are Bentley-specific, the internal piston kits and seals often share lineage with other high-end VW Group products like the Lamborghini Urus and Audi RS6/RS7 (4M/4G platforms).

• Weight: Despite their size, these calipers are “monobloc” (cast from a single piece of aluminum), making them exceptionally rigid and relatively lightweight for their scale.

4. Replacement & Service Notes

Software Requirement: When replacing these calipers, the braking system must be bled using a diagnostic tool (like ODIS) to cycle the ABS/ESP pump. Standard manual bleeding is often insufficient to remove air from the complex internal galleries of a 10-piston caliper.

• Hardware: Caliper mounting bolts are “stretch bolts” and should be replaced every time the caliper is removed.

  • Bolt Part Number: N91147601 (typical).

• Identification: Check the back of your existing caliper for a stamped code starting with 971 (Porsche-derived platform) or 3S.
