Abstract

A brake system for hydraulically actuating a pair of front wheel brakes and a pair of rear wheel brakes includes master cylinder fluidly connected to a reservoir and operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable in a manual push-through mode. First and second power transmission units are in fluid communication with the reservoir and selected front and rear wheel brakes. An electronic control unit selectively controls at least one of the first and second power transmission units. First and second two-position three-way valves are each hydraulically connected with a respective power transmission unit, the master cylinder, and a respective front wheel brake. The first and second two-position three-way valves are configured to place the master cylinder in push-through fluid-supplying connection with at least a corresponding one of the pair of front wheel brakes.
