Abstract
An electrically driven power brake booster having an electrically driven actuator. A lever is pivotably attached to a first pivot point coincident with a the pivot point of the operator controlled primary brake pedal lever. The lever has a first end and a second end, with the first end being attached to a brake rod of a master cylinder of a brake system and the second end being attached to the actuator. The actuator is activated by a signal indicating that braking is desired. This activation includes providing a first force to the second end sufficient to augment a second force from a brake pedal provided to the first end on the brake rod.
