i have an inconsistent problem with brake dust (or something like it).
a few months ago i noticed an over abundance of black material on the dishes of my rims. my first thought was brake dust, but it is more of a rubbery texture. thicker than typical brake dust. i thought i was rubbing and the inner fender liner was being rubbed off, but that wasn't the case. a few days later, it seemed to go away. about 5 months have passed and it never was that noticeable so i wrote it off. i let the car sit for a couple of weeks and when i took it out again, i experienced the same problem. in a major way. all wheels had this substance on them and it is not easy to remove. it's not just black dust/grime. it's physical pieces of a rubbery like substance. almost like a bunch of asphalt glued to the surface of the wheel dish. difficult to remove.
anything to be concerned with?
brake pads look fine.
