What is the purpose of a brake pad wear sensor?

A brake pad wear sensor is an electronic component that alerts you when your brake pads have worn down to a critical level. It typically triggers a warning light on your dashboard, indicating it's time to replace the pads to prevent further damage to the rotors and ensure safe braking.

How are these sensors tested for reliability?

PowerStop tests these brake wear sensors at temperatures up to 500F. This rigorous testing ensures they can withstand extreme conditions and maintain reliable electrode conductivity, providing consistent performance over time.
