BOOSTER TRAVEL SENSORThe travel sensor is a three-wire potentiometer that varies the voltage output as the position of the booster
diaphragm changes. The RBS module uses the position information to determine the amount of booster movement and hydraulic brake application.
-
BOOSTER VACUUM SENSORThe vacuum sensor consists of two signal circuits (redundant for safety) for calculation of brake system
operation requirements by the RBS.

PRIMARY PUSH RODThe primary push rod is redesigned so the ABS module and active booster will control the hydraulic brakes while the
