An electric actuator assembly for a drum brake assembly having a brake drum includes a housing and a gear nut configured for rotation by a motor and provided in the housing. A pin extends longitudinally within the housing and is associated with a first clevis for receiving a first brake shoe. A spindle extends longitudinally within the housing and is aligned with the pin. The spindle has a first threaded connection with a second clevis for receiving a second brake shoe and a second threaded connection with the gear nut. The distance between the first clevis and the second clevis increases in response to rotation of the gear nut to move the brake shoes towards the drake drum. The second clevis is urged towards the first clevis in response to cooling of the brake drum in order to back drive the spindle and gear nut and thereby reduce the distance between the first clevis and second clevis.
