Abstract

A computer system (11) comprising processing circuitry (13) configured to: receive a set of indications, including an indication (15) of a torque (T) provided to an S-cam (29) of a drum brake (7), and an indication (17) of an angular displacement (β) of the S-cam (29) resulting from the provided torque (T); determine, based on the set of indications, that the torque (T) is higher than a predefined threshold torque (T_TH) indicating contact between a brake lining (33a-b) of a brake shoe (31a-b) actuated by the S-cam (29) and an inner surface (37) of a brake drum (35), and the angular displacement (β) resulting from the provided torque (T) is less than a predefined threshold angular displacement ((β_TH) expected to result in contact between the brake lining (33a-b) and the inner surface (37) of the brake drum (35); and provide a signal (19) indicating that the drum brake (7) may have been overadjusted.
