Product Information
Informs you of when your brake pads reach their minimum thickness
Your BMW's brake pad wear sensors are simple devices. They are intended to be triggered when the brake pad becomes too thin. When they are triggered a light will illuminate on your dash telling you that your BMW requires a brake service. When replacing brake pads it is required to replace this sensor even if it has not been triggered.
 
WARNING: Proposition 65 information
Disc Brake Pad Wear Sensor
Disc Brake Pad Wear Sensors, or Brake Pad Sensor, as they're commonly called, are used as an instrument to alert the driver when the brake pads of the vehicle are at a low level and are in need of replacement. Operation of the sensor is simple where it is wired to the brake control module with 12v and when the brake pad becomes low enough, the sensor will ultimately surface and make contact with the rotor which in turn grounds the sensor and completes the circuit which triggers the light in your instrument cluster. The Brake Pad Wear Sensor is recommended to be replaced at the time of brake pad replacement.
 
About Bowa
BOWA engineers its brake wear sensors in Germany, which are then 100% manufactured in their modern factory in Poland. This means that every brake wear sensor offered by BOWA is produced by BOWA – nothing is re-boxed from other suppliers. Unlike the competition, who claim they are "the" OE Manufacturer, BOWA is the predominant supplier of brake wear sensors to the German car makers. BMW trusts BOWA almost exclusively for production and aftersales, shouldn't you?
