B. am Bremssattel angeordnete Elektromotoren (Motor an Caliper), entsprechend dem Fahrerwunsch ansteuert. Aus Sicherheitsgründen ist es vorgeschrieben, die Sensorik redundant auszuführen. Aber selbst bei redundanter Sensorik kann die Bremsanlage ausfallen, da das Steuergerät nur eingeschränkt zwischen falschen und richtigen Messwerten unterscheiden kann. Darüber hinaus kann im schlimmsten Fall auch das Steuergerät selbst fehlerhaft sein und ausfallen. Bekannte Bremsanlagen sind derzeit nicht in der Lage, solche Störungen ohne Probleme zu meistern.in Vehicles with a conventional hydraulic or pneumatic brake system consists of a mechanical Pass-through between the brake pedal and the individual wheel brakes.
