Sorry for the double posting, but...

I just put on new Brembo blanks yesterday and it rained overnight. Well, this morning the new rotor already had rust on all over it!! Will WD-40 prevent rust on them? Do I have to paint them? I hate the way it looks when the hub part and the tops of the discs are rusted.

The rust is unavoidable. It happens to us all. As soon as you drive and use your brakes once, the rust is scraped off. It's not bad rust, it's just a fact of life. You're not likely to see as much rust in the summer since there isn't as much moisture.

antarius

It's my understanding you can get coated rotors that dont rust. Nickel coated maybe?

E Swift

Once you brake, the rust comes right off.

VTechie

You can get nickel plated rotors, you can get cadmium plated rotors. I'm sure, if you wanted to, you could even find chrome plated rotors somewhere (note: this is a bad idea).

The problem with all of these is that the plating (or coating, if you prefer) gets taken right off the rotor. Unavoidable. The brakes are made of iron, and iron rusts. Period.

Now there is one alternative: carbon-carbon brakes. But really, that's only for racing, since they take a LOT of heat before they start working.

Just spray them down with WD40 or Tri-flow.....LOL

dynamite C1

they are right! you cannot avoid it from rusting! this rust is not the kind of "RUST" you see on domestics...whoops...j/k!

Rainmaker

Am I the only one here who thinks spraying your brakes with OIL is a BAD idea?

Rainmaker

betsuni

i'm with you rainmaker...oil on brake rotors is bad...

i had mine cad plated...although once used the plating on the disc that touches the brake pads came off, other parts that are exposed still have the cad plating and they don't rust. looks good too.

Chris

Only oil them for storage...and de-grease them before you put them on...


hehe....oil your brakes to prevent rust... more like prevent STOP!

Dirty GS-R

I was thinking the same thing.

dynamite C1

maybe yeah cuz I use cooking oil

junglistgsr

on the hub surface thing, not the part that the pad actually touches....the part the lugs mount onto and all that, you can spray paint em with engine paint like silver or a low gloss black or something and they wont rust....it looks a bit better too, mine are silver for now, im going to do them black....it only gets bad if you paint them colors like red-blue-yellow-green and stuff.

Chris

Warning: Do not paint the rotors.

I did once on my 240 and warped all 4 rotors. They will be out of balance and get warped after a few weeks.

Black SVT

Ok,this concerns me now.Is someone so **** that they can't deal with a little bit of rust on their rotors?

samagon

as soon as you stop the brake pads will scrape off any surface rust on the face of the rotor. as far as rust on the inside of the rotor, not much you can do about it.

wd40 would be a bad idea, it could possibly break down the pad material and will most cirtainly increase your stopping distance.

betsuni

LOL!!

does warpage apply to painted only? i had mine cad plated and doesn't seem to be a problem...

MattG

Oil on the rotors is a horrible idea!! With the heat that is generated durring breaking the oil will burn up. High temp grease is a much better idea LOL

Really just live with it. or get some stylish break covers from your local discount auto chain.

Phat Corolla

I was gonna say the same thing. Oil on brakes = break failure

_Shadow_

Just paint them like this. No more rust....no warping....looks good

vtecdc2

i knew someone with stainless steel brakes. they dont rust when wet, and they look differnt from other brakes. i didnt see the scratch marks that i usually see on brake rotors

Big Teggie

Cant you just clean it real good and then put some wax, that may repel water some bit. I dont mean the part that touches the pad.

Chris

Are you kidding!!!!!????? Are you sure they can hold up to the HEAT!??????

owen_the_soyboy

Guys, chill out with all the answers that dont help him out. he is talking about the specific areas on the rotor that the PAD DOES NOT TOUCH! of course you guys are right, oil on a rotor anywhere is asking for brake failure... you would not have friction which is why brakes work, friction!

I bought Powerslots when I had to do my first brake replacement, and they were shiny cad plated but all four began to rust on the rotor hat and in the crevice where the rotor disc meets the hat and also where the outside diameter / circumference of the rotor is. that pissed me off, I mean, they were plated, and I paid for it too, why else are powerslots so much loot!?!?!?! so that is the moment I decided I would stop making "appearance" mods on my car unless they were a side benefit of a performance upgrade.... light yet beautiful cf hood for example after my fender bender.

you CAN paint the rotor hat like in the pic above. not a bad idea, just do NOT use too much paint. in fact the paint will be nice and baked on after a few hard driving trips since the brakes get so hot! sweet! I gotta say this- I do NOT suggest painting the calipers, that retains heat and actually makes your brakes/fluid/pads more likely to fade to high heat during heavy use.

ACIN

Well, I'd like to say thanks to junglistgsr, shadow, and owen the soy boy for their helpful replies!!! To everyone else, of course I'm not talking about greasing or oiling the braking surface of the rotor.
