The move to make brake boosters electric began with the growing demand for electric and hybrid vehicles (EVs and HEVs). Since these vehicles feature smaller gas engines or no engines at all, there is insufficient or no suction pressure that can be used for braking. This led to growing demand for electric boosters. In recent years, the heightened need for greater vehicle safety has also increased demand for electric boosters.
