How does a BMW brake pad sensor work?
Electronic brake pad wear sensors replace the traditional metal squealer tabs found more commonly in braking systems. These tabs work by rubbing against the rotor once the pads have reached the end of their service life. A warning light will usually light up on the dash, indicating it’s time for a brake pad change.

How does the brake pad sensor work?
Electronic Pad Wear Sensors The wire connects near the brake pad very close to the rotor. Once the brake pad wears down past a certain point, the rotor will start rubbing up against the wire. Eventually, the wire will break and the change in resistance will cause the brake wear indicator to light up on the dashboard.
Do brake pads have sensors?
Electronic brake pad wear sensors eliminate the tab by using a small sensor – a loop of wire with a low current passing through it. As the pad wears out, the loop is exposed and make contacts with the rotor or disc , creating an open circuit.
How do you test brake wear sensors?
The brake pad warning light (red arrow) will be on when the sensor is seen to be open, or worn out. As soon as the circuit is closed, or a new sensor is installed, the light will go out. Set your DVOM to Ohms. To check resistance of the sensor , measure across the sensor terminals (red arrows).
