A brush warning indicator for an electric motor is described. The brush warning indicator includes a contact spring having a non-conductive bushing connected to a conductive member. The contact spring is connected to a brush yoke by a terminal. The non-conductive bushing contacts a brush in a brush holder and biases the contact spring in relation to the brush holder. Once the brush moves beyond a predetermined point, the conductive member contacts a contact rivet and relays a voltage to a remote location where an indicator signals that the brush has worn beyond the predetermined point.
