Claim:
1. A system for indicating wear of a brake pad attached to a vehicle, comprising: a brake housing; a brake pad mechanically coupled to the brake housing, the brake pad having electrically conductive material dispersed within an internal portion of the brake pad, wherein the internal portion is at least partially conductive to electrical current and has a measurable electrical resistivity; at least two electrodes at least partially contacting the internal portion of the brake pad, wherein the at least two electrodes measure the electrical resistivity of the internal portion, wherein the electrical resistivity indicates a thickness of the internal portion of the brake pad after the internal portion has been eroded by a rotating portion of a wheel, and wherein the electrical resistivity is proportional to the thickness; and an on-board electronic module electrically coupled to the at least two electrodes and mechanically coupled to the vehicle, wherein the on-board electronic module is configured to receive data associated with the thickness.
