What is the purpose of a brake pad wear sensor?

A brake pad wear sensor is a small electronic component that alerts you when your brake pads have worn down to a critical level. It typically makes a squealing noise or triggers a dashboard warning light, letting you know it's time to replace your pads before they damage other brake components like the rotors.

Does this sensor come with everything needed for installation?

Yes, this PowerStop wear sensor is designed for a direct fit and includes the necessary grommets, mounting clips, and cable protection sleeves to ensure a secure and watertight connection, just like the original part.

How is this sensor tested for reliability?

Each PowerStop brake wear sensor is tested at temperatures up to 500°F. This ensures that the sensor will continue to function accurately and reliably even under the high heat generated during normal braking.
