Abstract:
In a method for detecting air in the brake circuit of a motor vehicle having a hydraulic brake system that has a vacuum brake booster, the pressure prevailing in the vacuum chamber of the vacuum brake booster in the operated and the non-operated states of the brake is measured, and a parameter characteristic of the brake performance is determined as a function of the measured pressure, and the characteristic parameter is compared to a reference value.
