The pictures below are roto-tech rotors with less than 500 miles on them. The rust happened all in one night of rain. Notice how the rust don't come off near the cooling fins and just cover everything where the pads don't come in contact. These are fairly new rotors and aren't cheap on frozenrotors.com. Is all this rust normal because there are no other cars on the road with rust in the areas where I have it at.
Here's what happened to the rotors after another night of rain.
I had these pictures posted on another forum and people thought they look like they came from the junkyard. I do drive the car everyday and its not like the rust developed from a weeks period. I e-mailed someone from roto-tech and this is what they said.
Edward,
As you might not be aware, but all brake rotors are made out of cast Iron, which is very quick to rust once they been exposed to the weather. The only way rotors will not rust if they are platted with Zinc Chromium.
In regards to your pictures, you are correct there is rust all over your rotor, but just by looking at it I can see that you have not driven your car for a very long time or have let it sit outside for extended period of time. If any car is parked outside for over one week rust will build up on all parts of the rotor including the braking surface. If you were to visit a new car dealer ship you would see the something on all the new cars that are parked out side.
Regarding your second picture, that rotor looks like there is rust on it also, but as you can see there is no rust on the braking surface. I can assume that that rotor is always being used, or is stored indoors in a garage?
We at Roto-Tech want you to be happy with your rotors, and need to inform you that the rust will in no-way diminish the function of the braking. But I am sorry to say that this is the nature of cast iron, it will rust, unless they are treated with Zinc Chromium platting.
