Is this normal for a 2 year old car? (I only do about 3-4000 miles a year).

Yes it is normal and you don't drive it enough to keep them shiney. Everytime it sits for a couple days the rotors will rust(unless in the desert) and then under use the rust gets burnished off by the brakepads.
4K a year means they get rusty and clean more than most and will cause accelerated wear of the pads and rotors. Just the draw back of no/low miles.

Brake rotors (discs) are made from steel. Steel when exposed to water and air does rust. It is most apparent when the car has been sitting for awhile or just after you wash it and the rotors get wet. A little bit of surface rust will not harm the rotor. The disc brake pads will wipe this rust off when they are applied. If the car was to sit for a long time it could be a problem as the rust would eat so deeply into the rotor that it would not all be wiped off by the pads and it would continue to pit and eat into the rotor surface but if the car is driven regularly you should not have a problem. If you are concerned stop by a repair shop and ask them to inspect the brakes.

Your brake discs are bare metal so therefore if it rains or you wash the car then rust begins to appear. Its gets removed when you're using the car's brakes. It is also rust in the callipers that causes your brakes to cease, if the car isn't used for a long time.Yes it is normal for this to happen on any age car. Best to try and use it daily. Hope this answers your question

Because your disc rotors are iron, there is absolutely nothing on them to protect the metal from oxidation so they rust. It is completely normal and will not hurt anything, the first couple of times you use the brakes in the morning it will rub the rust off the rotor. If you live in s humid climate your rotors will rust overnight.

The rust is natural with no use. I see it every time I let a car sit for a while. Not to worry, within the first couple of brake applications it will be gone.

Iron content in the discs - some discolouration is normal but if it's heavy rust then the discs may not be up to scratch - there was one car recently (sorry, can't remember what it was) that had this problem and it was found that a batch of discs were faulty - nothing dangerous - just too much iron content

because the brake discs are basically bare metal if you think about it, even brand new cars get rusty faces if not driven for even a couple of days.
If the discs were treated metal, the pads would never bite, so they have to be special bare metal and wear like the pads

It is perfectly normal. You work it off as soon as you drive the car and brake. Check them after a run.
