What does a brake wear sensor wire do?

This sensor wire monitors the thickness of your brake pads. When the pads wear down to a certain point, the sensor triggers a warning light on your dashboard, letting you know it's time to replace the brake pads before they damage the rotors.

Does this sensor wire come with new brake pads?

No, this part is just the brake wear sensor wire. It is designed to be installed with new brake pads. You will need to purchase brake pads separately.

How do I know if I need to replace my brake wear sensor wire?

You typically need to replace the brake wear sensor wire when the brake warning light illuminates on your dashboard, or if the wire itself is damaged during brake pad replacement. This part is a direct replacement for the original sensor.
