PowerStop is on a mission to deliver an easy way for any driver to upgrade their brakes - no matter where or how they use their vehicle. Brake maintenance doesn’t stop at replacing brake pads and rotors. When it comes to the wear and tear on your brake pads, we recommend always replacing worn sensors with a new pair of easy-installation Euro-Stop Brake Wear Sensors. Our sensors are designed to meet the same form, fit and function as the original OEM part, and we pride ourselves in meeting or exceeding OEM requirements. In addition, each sensor is built to withstand extreme temperatures in order to ensure the greatest electrode conductivity. The PowerStop Brake Wear Sensors continue to work after thousands of miles, providing the safety and performance drivers count on.
