Monitoring a brake that includes first and second braking surfaces and a magnetizing device that, in response to the electric current supplied to them, are arranged to generate a magnetic field that is arranged to move the braking surfaces from a closed state, in which the braking surfaces are connected to each other, to an open state, in which the braking surfaces are separated from each other. Determining the electric current of the brake as the braking surfaces begin to move, from the closed state to the, open state, determining the maximum electric current of the magnetizing device of the brake in the open state, determining the condition of the brake as a current ratio from the electric current measured as the braking surfaces start to move to the maximum electric current. |
