Abstract

The invention discloses a method for determining the air content of the brake fluid in a hydraulic braking system. This method also permits determining the quality of the bleeding of the braking system.The principle of the method is a comparison of the volume intake with the respectively achieved pressure. The correlation is compared to nominal values. As the volume intake is determined by the clearance, the system is set by means of a pre-actuation to an initial condition before each actual measurement.
