Front Brake Disc Retaining Nut on 2018 AWD?

Went through and serviced the brakes on my daughters new to her 2018 AWD XLE. I had planned to pull the front discs to abrasively clean them but found what appears to be a retaining nut holding it on. (see image) The 2015 AllData manual (newest I could find) does not show a retaining nut there and of course had no information regarding torque and so forth. My question is - do the early Fourth Gen vehicles have this feature? Does any know what the torque value is for it? I did not take the disc off and just scoured it the best I could on the vehicle, but eventually I will need to take it off.


Thanks,


Rod

If you're referring to the black thing on the axle then it is retainer cup for the axle nut it covers. The disk most likely just rusted in place, the axle nut doesn't hold it. There are 2 threaded holes on the disk- those holes are used to push disk away from the hub by putting metric bolts in and tightening them up. I don't recall the exact thread size, someone might have it handy. Overall, looks pretty standard to me. Spray some penetrating oil into those 2 holes, let it soak for few hrs, put bolts in and it should go off easily.

Watch this video, he eventually removes the rotor. I used this vid when I did a 4 corner brake job on my '15 XLE.


Upon successful completion of the job you'll be entitled to wear one of these...

I haven't had a car that had an axle but holding the rotor on in 20 years LOL. If you're just cleaning the rotors take the 2 caliper bracket bolts out. You can then remove the caliper, brake pads and bracket as one unit. Take a piece of wood and hold it against the rotor. Use a hammer to hit the wood. Then do this on the other side of the rotor. After a few whacks the rotor will come off.

Thanks. It appeared that the disc was solid all the way under that cup. I gave it a yank, but did not whack it to break it loose on the assumption that it was retaining the disc. Thanks for the clarification!
