Power brake system

* If the power assist is lost because of a stalled engine or other reasons, the
brakes can normally still be applied with the power assist at least one time
by using reserve vacuum.
* The system is designed to bring the vehicle to a full stop on reserve
vacuum if the brake pedal is applied once and held down. However, the
reserve vacuum is partly used up each time the brake pedal is applied and
released.
