VACUUM BRAKE BOOSTER SYSTEM A vacuum brake booster provides power assist to the EV Vacuum brake booster system. As anyone who has experience a booster failure knows, the booster greatly reduces the effort required to stop the vehicle.Most brake boosters, have two or more chambers, divided by flexible diaphragms. The chamber is normally steel and the diaphragm is usually some form of rubber. They attach a metal push rod to the diaphragms and it moves with them. Vacuum, usually supplied by the engine and atmospheric pressure combine to provide the assistance during braking.
