    Abstract: A brake system is disclosed herein. The brake system includes an electromechanical brake actuator, a pressure plate, an end plate, a ball screw positioned between the electromechanical brake actuator and the pressure plate, and a plurality of rotating discs positioned between the pressure plate and the end plate. The electromechanical brake actuator is configured to extend the ball screw to a ball screw position to apply a requested force to the pressure plate towards the end plate thereby forcing the plurality of rotating discs together in an axial direction in order to reduce a rotational speed of the plurality of rotating discs. The ball screw is extended by the electromechanical brake actuator to the ball screw position based on a worn state of the plurality of rotating discs and a stiffness curve for the electromechanical brake actuator that represents force versus ball screw position for the worn state.

    Abstract: A braking system is disclosed. In various embodiments, the braking system includes a brake stack; an actuator configured to apply a compressive load to the brake stack; a servo valve coupled to a power source and to the actuator; and a brake control unit configured to operate the servo valve at a current ramp rate in response to a pedal deflection signal, wherein the current ramp rate is determined via a relationship between the current ramp rate and a brake pressure command signal.

    Abstract: A method for detecting a fault within a brake mechanism on an aircraft is disclosed. In various embodiments, the method includes activating, by a brake control unit, the brake mechanism; receiving, by the brake control unit, a wheel speed data for a wheel associated with the brake mechanism; determining, by the brake control unit, a wheel speed characteristic for the wheel associated with the brake mechanism; and detecting, by the brake control unit, whether the brake mechanism is faulty based on a comparison of the wheel speed characteristic and a wheel speed deceleration database.
