FOTU brand silicone paste

You won't need any pastes. You'll notice where the rotor hat drops onto the hub assembly over the wheel studs there's really no place to put paste or any lubrication for that matter The hub hat or the rotor hat the top of the hat rests on the face of the hub and that's it once the wheel nuts are tighten down that's it and sandwiched and can't go anywhere do anything but turn forward backward

 

I put Permatex anti-seize on the hub face. Definitely keeps rims from sticking. Very thin application, spread around with an old toothbrush, all that’s needed.

Also use it on points of contact between brake pads, shims and caliper.

For caliper slide pin I use Sil-Glyde Brake Lubricant.

 

The concern might be about having the rotor be hard to remove later. Sometimes, in rust-prone areas, the rotor can be pretty stubbornly stuck to the hub by the next time you want to work on it. A thin smidge of anti-seize around the center hole where it sits on the hub can make that less likely, if it's something you worry about.

A couple things:

• The original rotors do come with a couple of threaded holes that you can use, if need be, to help pop them off, by evenly tightening a couple machine screws (M8-1.25 if I remember right). Not all aftermarket rotors necessarily have those holes; if you're putting a new rotor on, you might check for that before it's too late, if you are worried about headaches later.
• The headaches mostly come if you leave the rotors untouched a long time. I do a quick brake inspection every time I rotate tires, and at that rate my rotors generally just flop right off when I lift the calipers. No anti-seize or special tactics needed.

One more thing: for the parts of the brakes where rubber boots or seals are involved, Toyota specifies a grease they call "rubber grease", which is not a silicone (it's a glycol, thickened with lithium soap). Toyota has reiterated that they will not use a silicone there. I don't know what Toyota's reasons are, and others here report using silicone instead anyway, but it's worth knowing Toyota's position on that.



If you buy the caliper-rebuild rubber kits from Toyota, they include little packets of the right grease, so you might never end up buying a tube like the above.

 

Yes.

 

Well that stuff will outlive me; what do I know.

 

Not sure. Anti-seize is more traditional, and likely more stable. Just get both?
