Rust on the rotor/hub

[doctor J]

This is common problem on most new cars due to "cuts in production cost".
I used antisieze to protect rotor mounting screws and threaded holes, so it will be possible to remove rotor in the future.
My old 79 Supra never had so much rust in this area

that's pretty normal. id get a wire brush (on your dremel tool or drill) and clean the rust off, mask off and paint it using duplicolor engine enamel paint.

That's all normal... Nothing to worry about... Try using a wire brush and it will be much better...

[doctordoom]

+1 for that being completely normal.

It's almost pointless to clean it though. It will just come back well within a few weeks.

Older cars used iron rotors just like new ones do. I can't think of very many that came with coated or painted hubs.

cleaning it is more for it to become a flat surface again, so that you can securely mount the wheel to the hub.

yah, you can paint it too after cleaning..and it will all look nice and prevent future rust. (not that the rust would hurt anything). good point about removing dust especially off the center bore area. that area sometimes binds the wheel real hard and wont let you get it off unless you do figure8's with your lugs loose. lol

try to give it some lubricant or grease, ive already do it on my car..

it will be prevent the rust for a few weeks..

Its always nice to clean up the hubs before you put your wheels back on. Did you clean them before? Did the rust come back like that?

Ya, it's a problem on most cars and really ugly on cars with nice/expensive wheel fitments and rusty rotors clearly visible behind the wheels. I have a process I've used for years on my rotors. Take a look at my Honda Fit web site for details.

Thanks for the info!

Ahhhhhhhhhhhh,I just think so

Metals that have the desired wear resistance and heat capacity all do this as they should rust. Part of the metallurgy. And my 79 looked every bit as 'bad' as thr ones you pictured, perhaps moreso.
If they didn't do that I'd worry.
Using nickel high temp lube is a great diea; just make sure there's none exposed to get on your rotors. And using the high temp grease on the studs is also advisable to make removal and torquing better.
