A manual release mechanism for a thrust reverser actuation system electromechanical brake includes a first release plate, a second release plate, at least two balls, and a handle. The first and second release plates each have grooves formed therein that have a cam surface located at a predetermined angle. The release plates face one another such that the grooves in each plate are substantially aligned, and the balls are each positioned in the aligned grooves. The first release plate is configured to rotate, and the second release plate is configured to translate. The handle is coupled to the first release plate to allow manual rotation thereof. In response to rotation of the first release plate, the second release plate will translate and disengage the electromechanical brake.
