ABSTRACT:
A material wear indication system is provided that includes a friction plate capable of engaging a moving surface and a wear indicator. The friction plate includes a wearable portion and a non-wearable portion. In one embodiment the wear indicator is embedded in the non-wearable portion and is prevented from contacting the moving surface until the wearable surface has been sufficiently eroded. When the wear indicator contacts the moving surface it emits a particulate matter that can be detected by a sensor. The sensor is operable to generate an electrical signal that is transmitted to a control unit when the wearable surface has eroded thereby exposing the wear indicator to the moving surface.
