Does brake dust buildup affect the stopping power or the rotors of the car?
A week or two of heavy build-up and you're probably looking at some effort to get the wheels clean, if not protected with a synthetic sealant like Klasse or Rejex. I once went 2+ weeks between cleanings of my wheels with my track pads on, I had to spend an hour per wheel minimum to get them clean. That was the last time I will ever a) go that long, b) leave the wheels unprotected.

The dust doesn't stick to rotors, it gets polished off every time you use your brakes, but it will stick to everything else in there, including your paint on the body. This is why regular washings are important as is keeping the paint protected.

An ounce of prevention...
