lite rust on rotors
Hello Guys/gals
I've gota question about Rust appearing on rotors. I started noticing rust forming on my rotors if I odn't drive the car for a few days. I wasn't sure if that was normal or not. They are Suby Rotors that I had Cryo Treated. I figured about after the first stop, most of the rust is knocked off. just wasn't sure if it should form so quickly.... or maybe I'm just being dumb...... someone let me know if this is normal or not..... I've noticed it on other cars but they had been sitting for serveral months. thanks SVX1999 |

Normal, normal, normal.
It's normal. I have two cars with 4 wheel disc. Both do that as well as my previous two cars with disc brakes. I know how you feel though. I can't think of anything good that comes from something rusting. (I own a Fiat so I am an authority on rust) Randy (I just HATE rust) ii |

That is perfectly normal. The easly solution is to drive it every day

agree with the above. the factory rotors appear to be unplated, machined, cast iron, so quick rusting is to be expected if there is humidity.

Lee (previous Fiat owner) P.S. one thing about the Fiat. I have never before, or since, had as many people ask if they could drive my car as when I had the 124 spyder - no idea why, just one of those bizarre facts of life. |

heh. Yep. Normal. If you wanna see something really crazy wash your car. Within one hour your rotors will have a tiny orange coating.
I bought rotors from 'raceconcepts.net' and the were zinc plated, so they've stayed silvery so far. The only part that rusts would be hte part where the pad touches the rotor because thats completely exposed bare metal. - Ca$h |

thanks guys
Hey everyone and thanks for the reply.
Yes your exactly right.. I figured not much good can come from anything rusting up very quickly. I live in the south so humidity is just a fact of life...... Cash, as a matter of fact I have noticed that.... Wash the car it's all lovely and shiney..... Except for the rotors. Lite orange spots appear on the bare metal surface..... Thanks again to all those that replied. svx1999 |

You know, you could prevent that by spraying WD40 on your rotors. Course, then you wouldn't be able to STOP. Heh. DO NOT DO THAT!!!

On my 1975 Norton Commando the factory hard chromed the rotors. I have heard from people, who had it ground off, that it decreases braking power by about 10 to 15%. I have no idea how it would work on vented rotors (the bike's rotors are solid), but they've never rusted in 27 years now.
Just an idea. i think a car's braking power would scrub the chrome off on the actual breaking surface, but the rest would stay relatively clean. I remember Beav put on some aftermarket slotted rotors that were cad plated, have to ask him how they have held up to Tenn weather. That would seem to be a cheaper solution. |

Thats what mine do. They're zinc coated so they're silvery and shiney. The only part that rusts is where the pad is. It's GREAT!
- Ca$h PS: Ceramic rotors...mmmmm |

Black is beautiful
CARBON-CARBON!!!
Of course most of the Rotors on sportbikes are steel. The hot ticket here is cast iron (stock on Ducati's). Somewhere on the net is the coeffecient of friction for most braking materials. IIRC Cast iron is way up there. |
