An automatic slack adjuster (1, 101, 201) for braking systems of automotive vehicles, in particular for drum brakes of commercial vehicles, includes a lever (3, 103, 203) configured to be operatively coupled to a push rod (117, 217) of a brake actuator, and to pivot about a rotational axis (R) when actuated by the push rod (117, 217), the rotational axis (R) having a predetermined fixed location relative to the vehicle. The stroke level of the slack adjuster (1, 101, 201) is moveable between a predetermined zero stroke position (7a, 107a, 207a) and a working stroke range (7b). The invention furthermore relates to a braking system (100) for an automotive vehicle and a wheelset (200) can include the slack adjuster. An electronic detection unit (98, 109, 209) determines the current stroke level of the automatic slack adjuster (1, 101, 201).
