oh 801 isn't the wrong number, 801 is with sensor and Bendix MKD648 is without sensor.
Edit:
wait do I need a sensor with the pads??? Now i'm getting myself confused
Why do some have and other have not sensors? Forgive me lord i'm stupid!
Edit again:
Some times I think we're all just a bunch of ants on god's ant farm. haha Stazi is right(of course hahaha) Cougars have brake wear sensors, Contours do not. Well not its on the forums because I searched and couldn't find anything on it.
