Abstract
A system and method are provided for monitoring brake wear of a brake assembly. A cam shaft may be coupled to a brake assembly and configured such that movement of the cam shaft engages and disengages the brake assembly, a cam shaft movement sensor produces a signal corresponding to a position of the cam shaft, and a control circuit assigns the signal produced by the cam shaft movement sensor at an unadjusted and unengaged position of the brake assembly to a reference cam shaft position, thereafter monitors the signal to determine an engaged cam shaft position when the brake assembly is engaged, and activates at least one indicator if the engaged cam shaft position exceeds a threshold cam shaft position stored in the memory unit. The threshold cam shaft position is based on the reference position and is a cam shaft position beyond which the brake assembly is worn.
