A moderate amount of surface rust has grown over the winter on the rotors. Should I just take it out and let normal braking remove this or should I attempt to clean up the rotors first? If I do the former it will be with my street pads on the car so it won't contaminate the track pads. Any concerns of "stuff" blocking up the cross drilled rotors? If a cleanup is desirable first, what method is used?

Not sure about the cross drilled issue as I run solid rotors, but I just do a few hard braking applications to clean the rust off in the spring. But admittedly I'm a terrible person, so this advice may be terrible as well.

I don't know, but according to what I've read, if you're not towing with a gooseneck and a one-ton dually truck, you're crazy.

Drive it.

Chris, are you signed up for the May UCR event (11-12)?

don't worry about it.

I use to actually 'age' my rotors, buying 6 at a time, greasing up the hubs and leaving them out in the sun to 'heat cycle' for months...

the longest lasting rotors I ever had were junk yard salvage rotors that were rusty, but fresh. the old rusty ones lasted longer than the cryro/frozen rotors.

*but the bearing surfaces need to be good/clean.

Yup - how about you?

pontifex4

Yes, indeed! I'll look for you. I'll be dressed like a fish.

Awesome - I will either be in my Mardi Gras Indian costume or in my Angus Young schoolboy outfit. Will see how I feel that morning.

Its normal.. Its just like a little tarnish.. Use them and they will look and be fine..

Good way to stop squeaking glazed brakes too. A buddy pointed out a good trick that I found works well. Wet the rotors (when they are cool) and let them flash rust overnight or so then drive them to cut the glaze from overheating stock type on track.

But seriously, you don't want the tail wagging the dog. When are we going shopping for toterhomes?

My 997 drilled rotors can literally rust even when there is humid weather. It makes a horrible noise when you first use the brakes and then they are shiny new again. Drive it.
