Bentley GT Pedal Accelerator Pedal Brake Pedal 3W1723139 3W1721503A

For the Bentley Continental GT, GTC, and Flying Spur (2004–2018), these part numbers identify the core pedal assembly components. In Bentley’s catalog, there is a distinct difference between the “Standard” rubber-faced pedals and the highly desirable “Alloy Sport Pedals” found in the Mulliner Specification.

1. Accelerator Pedal: 3W1721503A

This is the Electronic Accelerator Pedal Assembly. Since these vehicles use a “Drive-by-Wire” system, this unit is more than just a pedal; it is a high-precision sensor module.

• Compatibility: Fits all Gen 1 and Gen 2 Continental models (2004–2018).

• Supersession: This part is often interchangeable or superseded by 3W2721503C.

   

• Mechanism: It contains a dual-redundant potentiometer that sends your throttle position to the Engine Control Unit (ECU).

• Note: If your car has a “dead” throttle or a “Limp Mode” warning with pedal sensor fault codes, this entire assembly is usually replaced.

2. Brake Pedal: 3W1723139

This part number refers to the Brake Pedal Lever/Arm or the Brake Pedal Assembly.

• Construction: A heavy-duty steel forging designed to handle the high leverage required for the Bentley’s braking system.

• Integrated Parts: This assembly usually includes the mounting point for the Brake Light Switch (which is a common failure point if your brake lights stay on or your cruise control won’t engage).

   

• Standard vs. Sport: This part number represents the structural arm. The visual look (Rubber vs. Drilled Alloy) depends on which Pad/Cover is clipped onto the face of this arm.

3. The “Mulliner” Upgrade (Drilled Alloy)

If you are looking to upgrade your interior to the Mulliner look, you aren’t just looking for the arms, but the Alloy Pedal Pads.
