2006 F-53. Doing brake overhaul found rear rotors did NOT have ABS rings in them. Both hubs have ABS sensors, this is a 4 channel system. I had no ABS light on. Stupid me went and replaced the rot...
I had new rotors, calipers and pads put on my car, got an ABS light after, would come on and then go out. It took about a week of driving it and it finally stayed out
