The rotors on my cars get a coat of rust sitting overnight in the garage or in the drive
. As I backup and apply the brakes you can hear the rust getting cleaned off
. Not good for the pads. My '96 S-10 was worse than my HHRs. (Cheap Asian iron 
with not enough chrome)Boydie
Just one of the reasons why I always paint any of the bare metal, non pad contact areas of new rotors. Nothing worse than a clean car with rusted brakes showing thru the rims.

I don't understand where the rusty water is from coming?

The red painted Brembos do look good but I don't understand. The face of the rotor rusts and you can't paint that.

This wasn't about the caliper. It's just part of the picture I used to show the painted rotor.

Boydie,
I'm pretty sure rotors are made of cast iron not steel at all.
I could be wrong but I think if they used steel it would tend to 'work harden' in spots from normal breaking, then the brake pads could no longer get a good bite rendering the brakes useless.
Drum brake drums are made of cast iron for the same reason.

Cast iron only ? Not if it came from a Chinese factory. 
Remember. They're the country that buys millions of tons of our scrap metal. It gets shipped to China by the "boatload".....literally.
No telling what kind of metal winds up in their rotors and drums.
