Everyone calls them differently – but they all mean the same thing.

Brake pad sensors are also called warning contacts, brake wear indicators or brake wear sensors.

Brake pad sensors are installed in brake pads in different ways. They are either glued in or plugged in. In the aftersales market, only plug-in sensors are used. Brake pad sensors are subject to the same wear as the brake pad in which they are installed. When the brake lining has worn down to the wear limit, this is indicated to the driver by a visual signal.

New types of brake pad sensors have a multi-stage measuring system that can be used to provide the driver with more precise information about the remaining mileage of the brake pads.
