Abstract
A brake system includes a master cylinder, an electric servo brake, and an electric motor. The electric motor drives a screw that engages a pair of helical gears which are each mounted on a respective shaft. Each shaft further mounts a gear that meshes with a respective gear rack. The electric servo brake includes a body that defines rails which guide the gear racks. A lever is supported on each end by one of the gear racks, and is connected to a support via a pivot point. The support lies flat against a side of a reaction disk that lies against a push rod that actuates the master cylinder.
