Hello, everyone, could somebody tell me how to avoid rust on the brake disc? It seems there is some light rust on it.

It's normal and unavoidable. As soon as you drive it and use the brakes, it will disappear. It is simply a very thin layer of surface rust

What size rim/tires are you running? The rears look like it's rubbing.

18 inch. The tires and rims are new. Just less than 1Kms. I will have to check them.

Oaky, I see. Thanks. I will have to drive it more in winters.

if you`re talking about the part that is not touched by the pads, paint it. Rust resistant primer + 2/3 coats of paint.

Go for carbon ceramic next time!

It's a common issue with bmw brakes on lots of models. You can paint the areas that do not rub. Other than that it comes off when you use them. I still do not understand why they are not made of a different alloy or coating from the factory. Ceramic brakes do have this issue but are far more expensive.

Thanks for your info. I will see what I can do on that.

Thanks for you info. That would be way off my budget. I will see next time.

Thanks for your reply. Next time when I change car, I will think about this issue.

This is what you need and it works well. Or you can get a leaf blower to try getting all the water off the rotors.

My wife's 435 does that every time I wash it.

I usually move it down the driveway & then back up to get rid of it during the drying process.

Zimmerman rotors... no problems
