An electric brake assembly (200) for a rail vehicle includes: a rotating member mechanically coupled to an axle of the rail vehicle; at least one friction member (221; 221) movable between an engaged position in which the at least one friction member (221; 222) contacts the rotating member, and a disengaged position in which the rotating member is free to rotate without contacting the at least one friction member (221; 222); a gear assembly (220) arranged to mechanically operate on the at least one friction member (221; 222); an electric motor (230) controllable via a control signal (CS) and configured to cause the gear assembly (220) to act on the at least one friction member (221; 222) to move between the engaged position and the disengaged position; a force sensor (225) configured to generate a force signal indicative of the at least one friction member (221; a pressure signal (F) of the magnitude of the force when the rotating member is in contact with the rotating member; an angular position sensor (237) configured to generate a pulse count signal (PC), where each pulse count reflects a specific angular motion of an output shaft of the electric motor (230); and a controller (120) configured to obtain the pressure signal (F) and the pulse count signal (PC) and to define an origin position of the motor (230) based thereon.
