A brake pad wear sensing system for measuring brake pad wear for a vehicle disc brake system includes a brake pad wear sensor including a near field communication ("NFC") circuit for transmitting an NFC signal and a tank circuit including a resonating component and a charge storage component. The tank circuit powers the brake pad wear sensor including the NFC circuit. The tank circuit is configured to be inductively charged in response to interrogation by a NFC device positioned within a predetermined proximity of the brake pad wear sensor. The NFC circuit is configured to respond to the interrogation by the NFC device to transmit the NFC signal. The resonating component or the charge storage component has a physical condition or effective component value that is configured to be degradedin response to brake pad wear. The degradation of the resonating component or the charge storage component reducing the signal strength with which the NFC signal is transmitted. When a NFC or equivalent device has capability of determining the peak frequency response, then more accurate frequency determination method can be used.
