Claim:
1. An air-guiding device for cooling brakes in a motor vehicle, comprising: adjustable air-guiding flaps configurable to direct air to the brakes in the motor vehicle; an electronic control unit operatively coupled with the adjustable air-guiding flaps, the electronic control unit controlling the adjustable air-guiding flaps as a function of vehicle speed and as a function of pilot control pressure generated in a brake system upon activation of a brake pedal, wherein the electronic control unit is programmable configured to control the adjustable air-guiding flaps according to a first mode and a second mode, wherein the first mode operates to open the adjustable air-guiding flaps if the vehicle speed exceeds a defined upper speed threshold value while the pilot control pressure is above a defined upper pressure threshold value, for a predefined first period of time, and wherein the second mode operates to open the adjustable air-guiding flaps if the vehicle speed is between the upper speed threshold and a defined lower speed threshold value while the pilot control pressure is between the upper pressure threshold value and a defined lower pressure threshold value for a predefined second period of time.
