An electromechanical brake system comprises: a screw-nut mechanism comprising a rotatable body and a translatable body configured to be axially translatable relative to the rotatable body to move a brake pad according to rotation of the rotatable body; and an actuator assembly comprising a motor having a motor shaft, and a multiple-stage drive mechanism having belt and gear drive mechanisms and operably connecting between the motor shaft and the rotatable body of the screw-nut mechanism. The belt drive mechanism comprises: a drive belt; a drive pulley provided on the motor shaft; and a driven pulley connected to the drive pulley of the motor shaft via the drive belt, wherein the driven pulley is provided on an intermediate shaft. The gear drive mechanism comprises: a first gear provided on the intermediate shaft; and a second gear rotatably engaged with the first gear to rotate the rotatable body of the screw-nut mechanism.
