Is this normal on a brake disc? I know rust is normal on the surface and will be gone when the car is driven but is it also normal for rust to be on the rusty part in the photo? Car is 5 years old if that matters.

    Has to get pretty bad for it to actually cause problems. I usually will recommend rotors when it flakes off and that’s pretty uncommon where I’m at. Usually get replaced for being overheated/badly warped before that becomes a problem.
