A braking system for a vehicle, comprising: a plurality of wheel cylinders; an active booster master cylinder connected with said wheel cylinders; a controller for operating said active booster master cylinder; a primary master cylinder mounted remotely from said active booster master cylinder, with said primary master cylinder being operated by a brake pedal; a servo system, connected between said primary master cylinder and said active booster master cylinder, for providing a control input from said primary master cylinder to said active booster master cylinder; and a brake pedal travel sensor operatively connected with the brake pedal and with said controller, wherein said controller utilizes output from said brake pedal travel sensor to operate said active booster master cylinder without using said servo system during normal operation of said braking system, with said controller activating said servo system, so as to allow operation of said active booster master cylinder by means of said primary master cylinder in the event that control of said active booster master cylinder becomes impaired.
