Design and Function in the Braking System

The brake pedal assembly in the Mercedes W447 is responsible for the mechanical connection between the driver's foot and the main component of the braking system. The correctly selected lever, pivot point, and pedal travel range influence:

• precise dosing of braking force across the entire stroke range,
• repeatable pedal operation characteristics,
• ergonomic foot positioning relative to other control elements,
• proper cooperation with assistance and stability control systems.

An original brake pedal assembly is particularly important in vehicles with automatic transmissions, where the brake control system is closely linked to the transmission's operating logic and safety systems.
