Rotor Rust

I have new rotors on my Caddy and after driving for two hours in the rain, they have already began to turn orange. Are there any tricks to prevent this? My car looks great, as do my wheels but this is driving me nuts.
 
Rust on the rotors is like bad breath after having good food with garlic in it........there is no way to prevent it. As soon as you drive a few miles the rotors will look like new metal. Don't let this be a concern at all. Wish it would work the same for garlic!
 
The area that the pad touches will clean up next time you use your brakes.



For the rest of the rotor (hub, outer edge) you can use brake paint or buy zinc washed rotors.
 
Think of it as a good thing?



I've only seen noticable rotor rust on lots of high end cars. BMWs and Mercedes especially.



Or maybe I don't know what I'm talking about...

Ah, I've got it on the minivan too...always get it unless I get 'em zinc washed and they don't always do a perfect job of *that* either.



Oh, regarding the swept areas, I wouldn't let the vehicle sit for *too* long without clearing the rust off (by at least moving it around while riding the brakes). I've had issues from where water got trapped behind the pads and pitted the rotor surface, sure didn't expect *that* to happen!
 
I once saw a discussion on another forum about powder-coating the rotors. One guy thought it would be possible to powder coat the entire rotor and just let the pads wear off the contact surface without causing any problems, leaving the rest of the rotor protected. I wonder about the consequences of having the pads grip onto powder coat, but I have no idea what would actually happen. Does anyone have any idea whether this would work?

I'd be worried that the powdercoating would "gum" up the pads, leaving you with iffy brakes when they got hot. I suppose *if* you powdercoated the whole thing, you could have them turned to remove the excess... I dunno, I'll probably stick to painting the more noticeable surfaces and living with a little rotor rust.

I too wonder if the powdercoating would cause any issues :nixweiss It'd probably be a bit thicker than (normal) paint.



Somebody here (MBZ500E might be his username if you want to search for it, hard to remember as it was a long time ago) had his rotors plated in electroless nickel. Last I heard it worked out great and I've condidered doing it on the S8's rotors the next time I get new ones.
