Abstract
A brake pad life monitoring system can monitor the wear of a brake pad operatively coupled to a rotor. The brake pad life monitoring system includes an erodible, electrically non-conductive covering layer operatively coupled to the brake pad such that wear of the erodible, electrically non-conductive covering layer corresponds to the wear of the brake pad. Further, the brake pad life monitoring system includes an electrical circuit having a circuit path from a power supply to a ground. The electrical circuit is at least partially disposed on the erodible, electrically non-conductive covering layer and includes a first resistor connected in series with the power supply and a second resistor electrically connected in parallel with the power supply. The brake pad life monitoring system additionally includes a measuring device electrically connected to the electrical circuit.
