Abstract
The disclosure includes a system for indicating wear of a brake pad attached to a vehicle. The system can include a pad holder, a brake pad mechanically coupled to the pad holder, and a sensing device coupled to the brake pad and located at least partially within the cavity. The sensing device can include a first electrode and a second electrode embedded within the sensing device. The first electrode and the second electrode can measure electrical resistivity of an electrically conductive material located within the sensing device. The electrical resistivity can indicate a thickness of the internal portion of the brake pad after the internal portion has been eroded by the rotating portion of the wheel.
