An electric park brake (EPB) actuator unit 10 comprises an actuator housing 12 and a motor housing 14 integrally formed as one-piece with an actuator wall 18 of the actuator housing 12. The motor housing may include a stator 26 abutting the actuator wall and a rotor 24 received therein with a drive shaft 20 extending through the actuator wall into the interior of the actuator housing, wherein the shaft may be supported by a bearing 28 formed on the actuator wall. The EPB actuator may be used on a vehicle disc brake calliper and the actuator wall may support the drive shaft to inhibit any misalignment caused by relative movement between the motor and actuator.
