Abstract
An electro-hydrostatic brake system includes a motor controller configured to receive a brake command, a motor in electronic control communication with the motor controller, and a pump mechanically coupled to the motor. In various embodiments, the electro-hydrostatic brake system further includes a hydraulic tank fluidly coupled in fluid providing communication with the pump, a hydraulic pressure rail fluidly coupled in fluid receiving communication with the pump, and a brake actuator in fluid communication with the hydraulic pressure rail and configured to exert a braking force on a wheel, wherein the braking force is directly modulated by the motor and/or the pump.
