A system and procedures for adjusting brake mechanisms for an aircraft having an electric brake system are disclosed. The brake actuator mechanisms are controlled to achieve different parking brake actuation states as a function of the current engine run status (e.g., engine off, engine idle, or engine above idle). Procedures for adjusting an aircraft parking brake as disclosed herein include setting the brake actuator mechanisms to achieve a relatively low clamping force when the aircraft engines are off or idling, and setting the brake mechanisms to achieve a relatively high clamping force when the aircraft engines are running above idle, and to maintain commanded brake force without active or battery power by engaging a mechanical clutch or latch to the brake actuator.
