Dry Braking
- Additional function requirements dry braking:
- No brake intervention by a driver assistance system
- Speed: 50 km/h (31 MPH) or more
- Windshield wiper system switched on
- The status of the windshield wiper system is sent by the BCM over the CAN communication with the interface for the electronic ignition switch control unit to the electronic stability program control unit.
- The dry braking function enhances the performance of the brakes in wet driving conditions. The brake pads are applied cyclically for 1 second with a brake pressure of approx. 150 kPa (1.5 bar, 1.5 kg/cm2 , 22 psi) to remove the film of water from the brake disk rotor. This improves the response time of the brake.
