ABS Mystery
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...

My guess is the prior owner rigged the system somehow and you have the wrong rotors for the chassis model. I'm guessing your chassis is a 20.5K lbs which was a four channel system and 10 bolt hubs. My lighter chassis, 18.5K lbs is three channel and 10 bolt. Since both have 10 bolt wheel hubs and disks that are interchangeable.
How the system could be rigged not to fault without the ring I'm not sure since the system is looking for a train of pulses as the wheel rotates? I have no idea. Anything passive such as an open, short, a diode or resistor wouldn't do it.
