The invention relates to an actuator for brake shoes inside a drum brake of a motor vehicle, in particular with an electric motor. The invention also relates to a brake provided with such an actuator, for example a "drum-in-hat" composite brake or a dual-mode brake combining a service brake in "simplex" mode and a parking brake in "duo-servo" mode. The actuator includes a linear actuator assembly including a screw-and-nut system and is capable of separating the ends of the brake shoes. Said screw-and-nut system is driven by a transmission sub-assembly which in turn is driven by an electric motor. Said transmission sub-assembly rotates an element for actuating the linear actuation assembly using a guide rail connection. In particular, said actuator element is translatably movable in a single direction and rotatably fixed to a gear of the transmission sub-assembly.
