after i washed my car today, i noticed that my new disc brakes have a ton of rust on them, and they are only 3 months old! is this normal? i want to know if there are any products out there that could possibly remove the rust or prevent it.

 

it's normal, get used to it. once you stop a few times, tey will be shiney again where the pads make contact with the surface.

 

The rotor is made of high-carbon steel and will tend to rust when it is exposed to water or even a very humid day. The rust should be rubbed off by the brake pads after driving and stopping a few times after a few miles. Nothing to worry about.
I know there are some rotors made out of a different material that dont rust...but I cannt remember what it is.
