Brake wear and cement dust

I work out of state and park my 2004 Hyundai Elantra at the airport for 12 days at a time. The airport parking garage is being expanded and every time I come home my car is coated with cement dust. All the brakes on the car are rusting and need to be replaced. Question is - with the cement dust continuing, will the new brakes be affected by the dust accelerating the rust/wear?

AFAIK, cement is alkaline. In the presence of moisture, it will likely accelerate any rusting. However, I’d be far more worried about my paint finish than the brakes. This construction can’t last forever. In the meantime, can you use remote parking and take the shuttle?

You may want to buy a car cover.
