An electrically actuated brake assembly includes a brake disc, a brake pad, and an electric motor having a rotatable output shaft. A service brake transmission in operative rotational communication with the output shaft causes service braking of the vehicle in response to rotation of the output shaft, and an adjuster mechanism is operable to adjust a distance between the brake pad and the brake disc. An adjuster transmission operatively connected between the output shaft and the adjuster mechanism causes operative rotational communication between the output shaft and the adjuster mechanism when the adjuster transmission is engaged so as to transmit rotational movement of the output shaft to the adjuster mechanism, and causes there to be no operative rotational communication between the output shaft and the adjuster mechanism when the adjuster transmission is disengaged so as to not transmit rotational movement of the output shaft to the adjuster mechanism.
