Technician A says hybrids have an electrohydraulic brake assist system . Technician B says hybrids have an engine vacuum assisted power brake system. Who is correct?

Question

Quizplus · Accepted Answer

Hybrids typically use an electrohydraulic brake assist system due to the reduced or absent engine vacuum when the internal combustion engine is not running. Engine vacuum assisted power brake systems are common in conventional vehicles but not in hybrids, which can operate with the engine off, thus not providing the vacuum needed for such a system.
