Detecting overadjustment of drum brake

Abstract

A computer system comprising processing circuitry configured to: receive a set of indications, including an indication of a torque provided to an S-cam of a drum brake, and an indication of an angular displacement of the S-cam resulting from the provided torque; determine, based on the set of indications, that the torque is higher than a predefined threshold torque indicating contact between a brake lining of a brake shoe actuated by the S-cam and an inner surface of a brake drum, and the angular displacement resulting from the provided torque is less than a predefined threshold angular displacement expected to result in contact between the brake lining and the inner surface of the brake drum; and provide a signal indicating that the drum brake may have been overadjusted.
