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.
