2 Pairs Front + Rear Brake Pad Wear Sensor 7L0907637 7L0907637B 7L0907637C | Fit for Audi Q7, Porsche Cayenne, VW Touareg

Replace your worn brake pad wear sensors with this complete set of 2 front and 2 rear sensors. Designed for Audi Q7, Porsche Cayenne, and VW Touareg models from 2002 to 2010, these sensors help you maintain a critical safety system.

Your vehicle's brake pad wear sensor is a simple but important component. When your brake pads wear down to a certain level, the sensor completes a circuit that triggers a warning light on your dashboard. This set includes the correct length sensors for both the front and rear axles, ensuring accurate and timely warnings.

Each sensor is built to match the original equipment specifications for a direct fit. The front sensors measure 420 mm, and the rear sensors measure 225 mm, matching the factory requirements for your Audi, Porsche, or Volkswagen SUV. Installing new sensors when you replace your brake pads ensures your warning system remains fully functional.

This package gives you everything you need for a complete front and rear sensor replacement. Each sensor has been tested before delivery to help ensure reliable performance. Change the warning contacts together with the pads for the best results.

Mark noticed his brake warning light had been on for a few days. He had already ordered new brake pads for his 2008 Audi Q7, but realized the old wear sensors might not work correctly after the pad swap. He ordered this 4-piece sensor set. When the parts arrived, he replaced all four sensors during his brake job. After installation, the warning light turned off, and he drove with confidence knowing his brake monitoring system was working again.
