Is This Normal??!!

I got my new F15 in January and I noticed this today on my brake pads all of four wheels!!!

Yes, completely normal. I can see that you just washed your car. I found a great thread about it and this is what many members had agreed upon: "Rust on brake rotors is totally normal. It will form every time you wash your car and let it sit after. This happens with any car that has steel rotors which is 99.9999% of all cars with disc brakes." So, the best solution is to usually drive it a bit right after to let the brakes heat up and dry off for it to go away.

Here's the thread if you want to verify yourself . http://www.bimmerfest.com/forums/sho...d.php?t=248010

PS: Awesome wheel choice

There may be a little rust on the rotors but the wheels look fantastic!

Have the same problem. Asked the dealer and they recommended to wash it with CRL. Not sure if I should try or not.

Those are called rotors, and it's completely normal after a wash or even if your truck has been sitting still after a rainstorm. Once you start driving (and then braking), the rust will be scraped off by your brake pads.
