The invention relates to an electromechanical brake actuator for an aircraft wheel, comprising an electric motor (2) with a stator (3) and a rotor (4), a screw/nut assembly, of which one of the elements is rotationally driven by the motor and the other of the elements is compelled to slide without rotation to selectively exert a force on a stack of discs, the actuator comprising a park blocking member (10) suitable for selectively blocking the rotor of the motor at least when the sliding element exerts a force on the stack of discs. The park blocking member comprises a shuttle (17) that can move between a stable position of blocking of the rotor of the motor and a stable position of freeing the latter under the action of a pulse actuator (22, 24, 25) switching the shuttle from one position to the other, the brake actuator comprising means (9, 18) for forcing the shuttle to the freeing position when the motor of the brake actuator is powered.
