Dry braking of the brake discs on wet roads
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
Dry braking removes the moisture deposited on the brake disc when driving on wet roads or in the rain. Here, the brake pads are applied slightly. This function also shortens the brakes' response time. The DSC uses periodic, cyclical control to dial in lower brake pressures based on the speed of the windscreen wipers. The brake pads are cyclically applied. The brake discs are wiped regularly in the process. This creates no measurable deceleration on the vehicle. How often and for how long the brake pads are applied depends on:
- Intensity of rain, based on windscreen wiper speed, etc.
- Driving speed greater than 70 kph
