Wom 0 Report post Posted September 13, 2009 Yep should only be 2 sensors, left front and right rear. Idealy you should replace the sensor every pad change, but I'm not sure if it's absolutely necessary to do so. My car didn't have any sensors at all when I last changed my pads Quote Share this post Link to post Share on other sites
