Abstract

A device for ABS-integrated brake pad wear indication in a motor vehicle in which all line paths are constructed to avoid current loops and induction surfaces. All the wheel speed and pad wear signal lines respectively lead to the ABS or ABS/ASR control unit in a single strand or are combined at least via common fixings, grommets, intermediate connecting plugs and a single terminal connecting plug. Owing to coding of different warning signals for, e.g., ABS, ASR and brake pad wear, the signal connection between the ABS or ABS/ASR control unit and the instrument cluster in the dashboard is reduced to a single line.
