Late model F150 brake job..

[JTK]

Just a FYI, but a 2005 F150 4x2 takes a 36mm socket to remove the axle nut. I had to come to my brother's rescue on this today (he didn't have the socket). Two trips to the local parts store to get the right size $15 !@##$ socket. I didn't know Ford still used fixed rotors on the light trucks. Rotors like I've never seen. The bearings are snap ringed and 'sealed' into the rotors. The whole assy slides over a large machined turn on the steering knuckle spindle. The dealer wanted something like $120/ea for front rotors. AA had them for $78. Rotor, lug studs, bearing(obviously) and exciter ring are one assy. If it had been a floating rotor Chebby, he would have been done in an hour w/out needing me!

Sounds a lot like my old '83 F100. I hated changing the rotors on that beast. It was such a mess with all of the grease. I guess Ford chose to stick with what worked for them for 22 years (and likely more).
I wonder if the brake caliper is still held on with that strip of metal called a "key?" It wouldn't surprise me.

i hope you got new retaining nuts. they are nylock and cannot be reused. we keep bot Ford OEM and Motorcraft in stock at my dealer as well as an equal number of retaining nuts.

also these rotors must be machined with an on the car brake lathe, until a manufacturer makes an adapter for these particular rotors.

uhhmn, despite the universal warning not to re-use nylock nuts. I have done so without any issues to date. If you hand thread the nut on and it starts to bind when the lock engages the threads and then starts spinning the bolt, it is fine.

No he didn't replace the giant lock nuts. Regardless of being a hefty made pc, they are stamped right on them "DO NOT RE-USE" Dealer price was something like $17/ea for those IIRC. The Ford service counter guy claimed they rarely replace them. Honestly those looked like brand-new, including the nylon lock portion. On top of that, they are protected from spinning off by that castle nut/cover (not sure what it's called) Rippyman, yep they are similar to the old Fords, but there is no exposed tapered roller bearing. Basically just a machined bore in the center of the rotor that slides over a machined turn on the knuckle spindle.

just be aware, if i was the truck owner, and you did the brake work, and didnt replace those nuts and there were any issues, i would be a very rich man after the lawsuit. purposefully ignoring a step in thats not only in the service manual, but also where the fastener states "DO NOT REUSE" in very large letters is negligent.
