A drum brake assembly includes a brake drum, a brake shoe and lining assembly operably displaceable to contact the brake drum, and an electric actuator assembly. The electric actuator assembly has an electric motor with an output shaft, a gear reduction driven by the output shaft, a linear translation assembly having a gear nut driven by the gear reduction, and a connection portion of the linear translation assembly. The output shaft drives the gear reduction through a suitable gear type that can convert a rotation torque of the output shaft to the gear reduction at a right angle. The linear translation assembly linearly translates when the gear nut is driven. As a result of the linear translation, the connection portion actuates the brake shoe and lining assembly to contact the brake drum.
