Abstract

For the detection of undissolved gas in the brake system; hydraulic pressure is built up and at least one characteristic value for the pressure buildup such as the master cylinder pressure, the brake pedal distance, the drop in storage chamber pressure, etc., is checked to see if it exceeds a predetermined limit value. If this limit value is exceeded, it is assumed that there is an unacceptable amount of undissolved gas in the hydraulic component of the brake system.
