Vacuum Brake Booster: Description and Operation
The brake booster is a vacuum operated pedal assist providing more uniform and efficient braking. The braking force is doubled as compared to vehicles
without this unit.
Should the unit fail to function, its design enables the braking system of the vehicle to operate in a conventional manner. In such a case, fluid pressure is
obtained from the master cylinder.
