I have also been having issues with my front brake pad wear monitor sensor. overall it's not a big deal but it would just be nice to check the system once every month while you're driving instead of having to lift my truck and take off the wheel to look at my brake pad wear through the calipers.
I had been fiddling around with leveling my truck for the last couple of years and testing different size spacers on the Front Struts and my Brake Sensors were working fine and read the brake pad life fine, When I put on the 6 inch Rough Country Lift with the N3 Struts up front and shocks in rear, my front brake sensor now is not registering brake pad wear, I think this time around I must have either stretched the sensor cable too much and/or it has disconnected somewhere, I looked at the Spindles last weekend, where the sensor cable goes into it and it looks fine, I just haven't had the time to follow the cable and see where it goes into the Engine Bay, but will begin troubleshooting now that the weather is getting nicer.
