Operation

OPERATION

The BAS travel sensor (3) reports the position of the brake booster diaphragm plate to the Controller Antilock Brake (CAB). The BAS travel sensor rod is attached to the brake booster diaphragm plate (2). The diaphragm plate is located internal to the brake booster (1), and the sensor rod moves proportionally to the travel of the brake pedal. The travel sensor is used as an input to the CAB to determine the amount of driver braking effort.
