Hi all sifus.. I need help my wheel have a squeaking noise when i start driving for a few sec (like high pitch metal squeal) but it goes away after reach 20km/h above speed .. I suspect it comes from passenger side either from front or rear.. Had refer one mechanic and said the problem most likely cause by wheel rotor collide with brake pad.. Anyone can help what is the cause for this problem and the best solution to fix it? Or does anyone experience this problem before? My vehicle is BMW E46 318i.. Thank you..
