Currently, I am not experiencing this problem with my '98 528, but if I experience it with my incoming 323, there are a number of steps that I will take before going to the dealer.

1. Take out the rotors (all of them) and have them checked for warpness.

2. Use some anti seize lube to the areas on the rotor that will come in contact with the spindle (the holes where the lug nuts rest and the center hole as well as the back side of the rotors). This lube is metalic based and can not harm anything. Please becareful not to use the lube on the braking surface of the rotor. If you do, use some brake parts cleaner.

3. Apply some of the anti seize lube to the back of the pads also.

By doing this I am attempting to eliminate the clearances in the braking system. This process is time consuming and if you are not comfortable with working on cars, I DO NOT recommend it. If you choose to do this, fine, please do not use any other lubricants; other types of sprays, glues and lubricants just won't work. The anti sezie lube is available at NAPA parts stores. It has a very soft clay texture and has a color of silvery metals. Good luck.
