Braking Readiness

If the DSC system notices that the accelerator pedal is released quickly, the brakes are immediately pretensioned, to shorten the brake apply response time. To accomplish this task the DSC system generates a low braking pressure by applying a PWM signal to the solenoid valves, without creating any measurable deceleration of the vehicle. By applying a small amount of brake pressure the working clearance between the brake pads and brake disc is reduced. If the brakes are not applied within a certain time, the brake pressure that was applied is reduced.

The pre-tensioning of the brakes depends on the vehicle's speed (above 70 km/h).

The Brake Readiness function is activated under the following conditions:

• Vehicle speed > 70 km/h
• Minimum time between rapid accelerator pedal release and brake application < 8 sec. (DME provides the signal regarding rapid release of accelerator pedal to DSC via PT-CAN)
