Brake Pad Wear Sensors from StopTech for 1999-2006 BMW 3-Series & M3 [E46]


Quick Overview

You'll need these new sensors to replace your destroyed sensors after your brake pads are worn!

Application / Vehicle

Now available are StopTech Brake Pad Wear replacement Sensors for your BMW E46 3 Series or M3. Replace your old, unusable sensors with these brand new, high quality StopTech sensors when getting your brakes done.

Why Would I Need New Sensors?
Your BMW has eight brake pads, but only two of them are actually monitored for wear (the inner driver's side front pad and inner passenger rear pad). When a pad has worn down to below 2mm or remaining frictional material, the rotor will chew through a small plastic bump on the sensor which slices the wire in half and causes your car to show a warning sign on your dash. This is usually warning you that you will need new pads soon. However, once a sensor has been used and a warning has shown, the sensor is destroyed and must be replaced with a new one.
