How can I remove rotor rust?

wrx2 · 10-29-2003, 01:49 PM

Hey, guys and girls
I don't know if its right forum but I need little help. I just replaced DBA4000 front rotors last week and I already got bad rust spots all over the place after few days rainning. I used brake cleaner and WD40 but it didn't come off. It looks so bad.
Anyone know how to clean up rust spots on rotors?
Thanks,

If it's just on the contact area, the rust will come off when you hti the breaks. If you're tlaking about the whole rotor, then I don't know how to protect it..

...I know how to protect from the rust would be to, sand, primer, and paint. Make sure you tape the brake surface area befor though!

Thanks for your inputs. The rusted area is non contact area including edge where the pads doesn't contact and center hub area.

I think you can get them cadmium (or something like that) plated to protect against rust but I don't know if you can do it when they are already used and rusting.

Best thing to do is pull the rotors off, clean them, paint them, then bake them. I'd say get some good high-temp exhaust header paint, good to over 1000 degrees. Paint the whole rotor, even the contact area. The paint won't stand a chance against your pads and the brakes hydraulics. New rotors come with a anti-rust coating that the pads take off quickly, so don't worry about your brakes not working.

It's safe to clean off the rotor and spray those areas with high temp paint. Make sure you use something that's rated to at least 1200F. Stove paint, manifold paint and BBQ grill paint should do the trick.

Don't paint the contact area.

Hmmm you mean like this:

As above, no probs with painting the contact surfaces IMO. The pads clean it off nicely. That is VHT manifold paint BTW baked on at 600 degrees.

it doesn't hurt to paint the contact area. just go for a quick drive after the paint sets and the pads will scrub it right off.
