Brake Disk Bolts

Postby guitarzan » Fri Jun 17, 2016 5:28 pm



Hi,
I have to put my brake disk back on and does anyone know if I should put lock tight on them or anti-seize on them. 29 ft pounds tight.

Thank you
Frank

My FSM doesn't say anything about anti-seize or loctite. So, if you clean the bolt threads and properly torque them you should be fine.

Those who say it cannot be done should try not to interrupt those who are doing it.

Thank you so much Russell. That's what I'll do, clean them up and tighten them down.

Thanks
Frank

I read something one time regarding torque, that related to the application of grease or other lubricants. They indicated that lubrication of threads on a torqued assembly was not needed, or advisable. The lubricant will cause the torque applied to the threads to be higher than indicated by a wrench, and possibly lead to stripped or damaged threads. Made sense to me.

That does make sense to me too. Thinking about it, it sounds familiar to me. Maybe it was on this site.

Thank you
Frank

The disk rotor bolts come with a treatment on them. It looks to be a vinyl compound, similar to what is applied to Patch Lock bolts. The vinyl is a means to lock threaded fasteners without having to apply a separate locking compound. A typical bolt will have a nylon patch bonded to the threads which adds holding power and withstands temperatures from –58° to 250° F. In the absence of that vinyl patch on used bolts, I would suggest using the medium strength thread locking compound of your choice. I personally use the Blue Loc-Tite thread locking compound.

Hi Mike,
Will I be able to see this on the treads of the bolts? I really didn't look at them that close. I'll take a look at them. I couldn't find anything in the service manual. Gee you would think they would mention that. Thank you

If you have a new bolt, yes, you will be able to see the locking agent on the bolt.
This is a new bolt out of the package and you can see the green material in the threads. I don't think the color of of the material has any bearing on the strength of the compound. I have seen bolts with blue, red, yellow and green on them.


If you are dealing with used bolts that you have removed from the wheel, you probably will only see trace amounts of the locking agent.
As long as the bolts are in good shape, just clean them up and reuse them and apply some medium grade, normally blue, locking compound to them before installation.

The bolts from the factory had a locking agent on them. I agree with the application of blue loctite. FWIW :)

Thank you for that great picture. Talk about a picture being worth a thousand words. Just let me say thank you all again.

What a great group of folks we have here.
