Electro-Servo Brakes

Inspired by the Acura NSX Type S supercar, the Electro-Servo Brake system is hydraulic from the master cylinder to the 4-wheel disc brakes, just like a traditional braking system. The key difference is that the braking function is electronically controlled rather than a purely mechanical activation. The system offers excellent feel and feedback for the driver through the brake pedal.

When the driver applies the brake pedal, a signal is sent to the vehicle's Electronic Servo Brake ECU, which determines the appropriate amount of braking force to be applied by the hydraulic braking system. As in a traditional braking system, a hydraulic master cylinder then pumps brake fluid through the system; however, midway between the master cylinder and the calipers is a separate motorized electronic actuator, the same actuator used in the NSX Type S. This actuator receives an electronic signal, generated in the master cylinder module, that measures how the driver has applied the brakes – soft or hard, slow or fast – and precisely defines how much hydraulic pressure is apportioned to the brake calipers at each wheel. The system provides a consistent, linear and predictable brake pedal feel, regardless of driving conditions.

An additional benefit of the Electro-Servo Brakes is the ability for engineers to finely tune the brake pedal force and electronically control the brake pressure to optimize pedal feel and braking performance for a premium sport sedan driving experience.
