Rust is not an issue for me and there has been enough feedback on Hawk Performance Ceramic pads that I'm comfortable with their performance.

Good info guys..

I will try some hydes rust stopper. Only an issue for the winter months. Sounds like it's not a big deal and will come off on next drive anyway.

Sarcasm. But is it any sillier than worrying about surface oxidation on a rotor, or spending time spraying them when you can drive to the end of your driveway?

Its normal for the rust to occur with moisture in the air. Just a few revolutions of the wheels with the brakes applied removes all.

Next time, order PCCBs on your Porsche. 103,000 miles and not a spec of rust--and neither on the hats, either, which are aluminum.

+1 on the PCCB brakes. Liked them so much on my 997, I'm retrofitting them to my Cayenne. No dust, no rust after washing, incredible braking performance without any fade, and rotors with proper care and pad replacement at 50% wear will last the life of the car if street driven.

With iron rotors, the rust isn't really a problem, but the first drive that scrapes it off, deposits all the rust dust on the inner barrel of the wheel, which then requires another quick cleaning.

I'd be careful about spraying anything on your rotors. Sounds like that product is designed for it, but I personally don't want anything coming between the pad material and the rotor surface since what makes the brakes stop well is bedding the pad material into the rotor so you have effectively pad material to pad material contact when stopping. Introducing a foreign material to that equation just doesn't seem like the best idea to me.

Sometimes, when my car sits in the garage for a day or two, it gets dusty. Any ideas?

Petza914

I have some stuff you can spray on.

Nobody's panties are in a wad over this but you. Lighten up, Francis.

And sanding the rotors is no less ridiculous than spraying them with some rust inhibitor every time you park the car. Is he supposed to put the car on a lift and spray the backsides of the rotors as well? Because they rust, too.

If the car just sits still and looks pretty, I'd recommend Cosmolene.

You will reduce brake dust and reduce your unsprung weight by converting to PCCB's but you will not increase your breaking performance.

Gonzo...appreciate the input. Sorry if the question isn't up to your standards.

I figured it was a common concern given how many of us park the cars for the winter.

While I don't stress it, what I don't understand is why they rust in the 1st place (dumb question I know) as my and I'm sure pretty much everybody elses daily driver doesn't rust.
What's so different about their discs?

Mumbles

I do believe that the steel is cast so its prone to surface rusting

Gonzo911

I actually have very low standards...
