MB DOC, thanks for your post. After researching the problem I realize that the dust cover was rubbing against the inside of my oem rims. While at my buddy house I took my 18" Chrome wheels off the car and put my factory rims back on the car. It was not the parking brakes as I suspected, the problem was the dust cover that got bent somehow and begin to rub a ring in the inside of my factory wheel. It was late in the evening and I did not notice the ring around the wheel until the next day.
