| 主权项 | 1. A method for monitoring a brake which is operated by a spring force, comprising the steps of: taking into account a value which is required to load or bias at least one spring to a biased state, the biased state corresponding to a limit position; indicating when the at least one spring reaches the limit position; and comparing the value required to reach the limit position with a predetermined value. | ||
