What does a brake pad wear sensor do?

This electronic sensor 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 them.

Do I need to modify anything to install this sensor?

No, this sensor is designed as a direct replacement. It includes all necessary grommets and clips and requires no modifications for installation, ensuring a proper fit.

How do I know if I need to replace my brake pad wear sensors?

You should replace your brake pad wear sensors whenever you replace your brake pads, especially if the old sensors were worn or triggered the warning light. This ensures continued accurate monitoring of your new pads.
