Fading Brake Support

Fading means: the braking effect diminishes due to high brake disc temperature. As a reaction to detected fading, DSC increases the brake pressure beyond the brake pressure applied by the driver. At very high brake disc temperature, the fading compensation leads to the following being displayed:

• Brake warning lamp in yellow
• Check Control symbol in the LC display in the instrument cluster in yellow

The DSC detects fading as follows: The DSC compares the current vehicle deceleration with a setpoint value related to the current brake pressure. The DSC increases the brake pressure until the target deceleration is reached or until all the wheels are subject to ABS control. The operation is terminated when the brake pedal is no longer pressed or a speed threshold is undershot.
