All I have to do is wash the car, and by the time I'm done there is a surface layer of rust on the rotors. I know it only requires a short little drive to clean off, but it looks disgusting

Yuck!

Btw, it's a 2006 C230SS.

Get a Porsche with the optional ceramic rotors, no more rust.

Porsche also "fine tunes" the braking systems, resulting from extensive testing. For example, they found that a turbo charged vehicle requires red calipers to brake properly.

On that same line, they found that ceramic brakes require yellow calipers.

lol...good one...

And the AMG badge adds 15 rwhp right?

Roadmaster 1994 LT1 went thru a local auction for $700 last week.

Yeah the ones in bad shape hold no value. Hell the clean ones don't keep much value either. The exceptionally mint condition ones sell through Buick clubs and the sort for just under $10K.

It's a very fun car, but when it comes down to it, it's just a 10 year old American car.

The only reason for any interest is it shares the same engine/drivetrain as the 94-96 Chevy Impalas, so mods are cheap and plentiful.

And yes, we bought the car new.

Btw Cdiken, what does that have to do with my post about the rusty rotors on our C230? :p

cdiken

was responding to the wingless post about Ceramic rotors, and saw a giant picture of a Roadmaster.

I'd like to get a cheap Roadmaster and use it for a Roast Master. Disconnect and plug the right-rear brake line, and just stand and burn the rear wheels with the moster torque of the LT1 through an open differential.

i dont think its rust. its the combination of water and brake dust that puts a coat on the rotor. don't worry about it.

Untouchable08

yea my dealer just told me to paint them..its not rust.

wingless

Right. That dull, golden-brown patina that appears when water dries on unprotected steel in an oxygen-rich environment is not rust, it’s … something totally different.
Please post pictures of your painted rotors. Please also post pictures after these have been used to show how well they last.

mine were done, i will post pics later

It is rust by definition. Can't stop it on steel rotors.

ClayJ

EXACTLY.

I have yet to see it. I'm assuming you just paint the part that is not swept by the brake pads.

Roupin

My Roadmaster has an LSD...I roast both tires.

Btw, linelock only goes for about $100.

As for the rotors on the C230, the "petina" is definitely rust and CANNOT be painted. The paint will interfere with the heat transfer of the rotors to begin with.

Secondly, I was merely surprised that MB uses rotors that haven't been treated (zinc wash?) to prevent this rusting. The rotors on my Jeep or Buick don't rust at all and the MB kind of ticked me off in that aspect.

Oh well...

You can paint the area near the center, where the pads don't make contact.

You'll always have rust after you get water on the rotors though - nothing you can do about that.

Roupin

Any sort of paint or powdercoat on ANY part of the rotor will interfere with the heat transfer. I just got to see proof of that a couple months ago on another board I'm on, after someone powdercoated the center portion.

I would "upgrade" the rotors to a different brand if I could to get rid of the rust issue, but I'm also concerned about aftermarket cross drilled rotors.

The OEM rotors have their holes cast into the rotor, while the aftermarket idiots drill them with a freakin drill after they are made.

Oh well, I guess I'll just have to live with this gripe. Can't really complain since everything else on the car is 100%.

Where did you get the information about the colored calipers?

ClayJ

Hearsay has it that CGT's come standard with the yellow calipers (and with ceramic rotors) and that another color (like red) is an option in ordering.... Maybe the other models with turbos come standard with red calipers?

You think that's where he got it from?

mick1

the reason you hate them is because your car is still new. When it gets a little bit older, you will not care about those rusty rotors anymore

vraa

I was referring more so to the part where he mentioned that the brake types 'required' those color calipers.

I was under the impression that painted calipers are strictly a cosmetic modification.

ClayJ

And I wasn't being facetious?!!! LOL. I do think that the CGT's come standard painted in yellow, and the turbo'd models in red.... I almost always paint my calipersif they don't come that way just for the cleanliness factor....
Believe me, the color of the paint has nothing to do with their performance, Icky Ricky! LOL Now don't you worry your pretty little head or lose any sleep over this, OK? hahahahahaha.

LowCaliTi

cam fone pics, real quick, but u can see where is painted, had them preped and painted at my buddies body shop, looks 110% better, i hate rusty rotors too

SeaCoupe

I'm honestly a bit perplexed that you have enough energy to "hate" rusted rotors. Too much time on your hands. All respect to you for buying a Mercedes, but this goes way beyond concern.

LowCaliTi

sorry for tryn to "keep it clean" i like all my stuff fresh, new, clean, detailed, or whatever. but deff not too mutch time. but enjoy YOUR rusty rotors pal

SeaCoupe

You are TRULY missing the point here. Let me be simple:
You wash, you dry. Rotors are rusted. How long does it take before you drive your car? If it is THAT important. Put it in forward, drive, then park. Feel better?

Emoticans simply not needed here.
