i have stock brakes on my 87, and i have chrome rims, and i can clean the rims and polish them and within like 20 minutes of driving the front rims are covered in brake dust. The pads are new, but does this happen because they are cheap pads? Now i know it is obviously going to happen, it just seems excessive...i was thinking about getting the dust shields but im not sure about them. I kind of figured it was because they are cheap pads and not the expensive ones that have less dust. Any opinions?
