Abstract: A method relates to the manufacture of a drum for a spring brake for an electromechanical actuator, the drum including a housing configured to house at least one helical spring, an input member and an output member. The housing has an internal friction surface configured to cooperate with at least one coil of the helical spring. The method includes at least one step of mechanical surface treatment of the inner surface of the housing of the drum, the mechanical surface treatment of the inner surface of the housing of the drum being a step of creating grooves on the inner surface of the housing.

Abstract: An electromechanical actuator (11) includes a sealing element (21) provided with a housing (22), an electronic control unit (15) electrically connected to a first electrical connector (23), and a power supply cable (18) including, at one of the ends of same, a second electrical connector (24). The second connector (24) includes an elastic tab (26) provided with a stop element (27) cooperating with a recess (28) provided in the housing (22), and a first bending area (32) provided at the junction between a first end (26a) of the elastic tab (26) and a body (25) of the second connector (24). The stop element (27) is provided at a second free end (26b) of the elastic tab (26). The elastic tab (26) includes a second bending area (33) provided at the junction between an arm (37) and the stop element (27) of the elastic tab (26).
