I've noticed that whenever I wash my car, when the water gets on the rotors and then dries up, there is a thin film of Orange on the Rotors.
Almost like rust, actually, it probably is rust, but it comes off with wheel cleaner or if I drive around the block and brake for a long time / hard, it will also come off.

Should I be worried about this?

dont b worried, its just a surface rust that is no prob

Yanki01

normal. I think there's some type of wheel cleaner that doesnt produce it tho. not to sure what it is?

ok cool

TheQuietThings

this happens on all cars lol

mike6789k

lol not on my old camry... but maybe that was because i had steelies with hubcaps and couldnt see the rotors!

tikbhoy

only worry if its cracked or warped

matt

yeah that happened on my stock rotors before i got my drilled slotted ones. my new ones have a zinc coating so that doesnt happen on the new ones.

LiquidFX

lucky, i want a new set of rotors

normal on all disc brakes

whats the point of drilled / slotted?

are they larger? the stock ones look so dinky... loool

The holes or slots in rotors that are drilled or slotted allow for more air to flow past the disc and shoes to help cool them.

slots and holes used to have a point (and still do to an extent in racing set-ups), but for street cars they're mostly for look

oh haha

even if there's a wheel cleaner that wont make rust form, rinsing it off with water will

I have drilled and slotted rotors (on an xB mind you) and yes, it was due to this very problem. I hated seeing them with the surface rust. I noticed slightly better braking with the new rotors, but it was all about looks when I replaced them.

surface rust caused by iron in drinking water. If you notice it dosen't do it when it rains.

I don't know, my rotors are in my rotary engine!

My rotors turn orange when my car sits in the rain for a little bit. I usually don't have a problem with them turning orange when I wash my car though. Weird.
