My car has developed a metallic rattling noise over the past few weeks when going over bumpy or cobbled road. Sounds like its coming from the front right wheel area. If the press the brakes the sound goes away. Had the suspension checked and all seems ok. Only thing that was done recently on the car was new disks and pads on the front. I know the disks and pads are of questionable quality so could it be a pad thats not fitting 100% rattling around in there?
