A self-checking device and method for an elevator braking device and an elevator system. The self-checking device includes an inductance testing module configured to measure an electromagnetic brake coil inductance L of the braking device; and a processing module electrically connected to the inductance testing module, and storing a mathematical model of an air gap a between the movable plate and the static plate with respect to the brake coil inductance L in a brake state; the processing module is configured to execute a checking mode in the brake state of the braking device, and in the checking mode, the processing module receives a current inductance L0 measured by the inductance testing module, calculates a current air gap a0 based on the mathematical model stored, and determines a wear degree of the friction lining based on the current air gap a0 calculated.
