The rotors on my Z28 are rusty from sitting so long without use. Would it be stupid to clean the surface rust off with sand paper? I'd have them turned but they're still pretty thick.

Try driving it and using the brakes will remove the surface rust on rotors. Forget the sandpaper routine.

Sanding won't hurt them. Don't be afraid to use realy course paper to get the rust off. If you have any adverse effects once you start driving it, you may have to have them turned, but it's not very likely.
I am a firm believer in not turning a rotor. For the price of rotors on outr cars especially, just toss it and get a new ones. I think they are about $40 ea?
Another thing as well..always use a torque wrench on wheel nuts, overtorqueing wheel nuts can warp the rotors. Imports are really bad for this with their fancy 'engineered' brakes! (not overweight, undersized parts) ha

WD 40 and steel wool. Then wipe em off and brake hard a couple times. Mine rust up on me every year after sitting the winter. Not as rusty as yours, but yours aren't bad at all considering how long it's been sitting.

aint no better sandpaper then yer brake pads.
Would WD 40 soak into the pads or anything at all?? Would you want to spray them with brake cleaner or something after to get rid of the oil?

Anytime you get anything on the rotors you should clean them with brake cleaner, even fingerprints.

WD 40 has worked every spring for me, you wipe it off after of course, but I never cleaned it with brake cleaner after.
Brake cleaner, contact and electric motor cleaner are pretty much the same. It says so on some cans. Wd 40 is also a contact and motor cleaner. I've never had a problem.

WD40 is also a lubricant, not something I'd want on my brakes.

Ditto. WD40 is like tranny fluid in the sense it's detergent like but is still a lubricant. Only use brake cleaner. That stuff is a must for any car guy anyway Originally posted by Apeiron

I scuff the pads with sandpaper too if I see it starting to glaze

Yea you guys are thinking way too much, the brakes wear it off in about 1.3 seconds.Originally posted by RegaPlanet

I'm surprised someone didn't break WD-40 down into it's molecular state for everyone to see.
We carry it in gallon drums at work, with little pictures on the back, one of which is a picture of a disc brake setup with (brake cleaner) in captions.
But whatever.
