Zusammenfassung:A brake pad monitoring sensor includes an erodible, electrically non-conductive body, and an electrical circuit disposed within the body. The electrical circuit includes a first wear indicating portion. Electrical continuity of the first wear indicating portion is broken when the body erodes, in response to abrasion against a brake rotor, beyond a first depth relative to a contact surface of the body, to sense a first degree of wear. The electrical circuit includes a first thermocouple that is operable to generate a temperature dependent voltage signal for sensing a temperature of the brake pad. The brake pad monitoring sensor may be used to determine both brake pad wear, and brake pad temperature.
