Brake Standby
Quick release of the accelerator pedal causes the brake pads to be applied against the
brake disc thus reducing the stopping distance (by approx.. 30 cm/100 km/h) during
emergency braking. The DSC module builds up slight brake pressure (approx. 2.5 bar)
temporarily (approx. 0.5 seconds) in order to eliminate the clearance between the brake
pad and brake disc by applying the brake pads.
The brake standby function is activated under following conditions:
• Driving speed > 70 km/h
• Minimum time between brake application 8 s
• The brake standby function is not activated in connection with sudden acceleration
(sports driving style).
The DME/DDE control unit makes available the signal indicating quick release of the
accelerator pedal via the PT-CAN.
The sensitive driver may perceive a slightly harder brake pedal. No delay or noise is dis-
cernible for the driver.
