I change my break pads about 3 wks ago. I'm using some hawks hps now. Just a few days ago I started to hear a clicking sound when the car is moving. The sound seems to be coming from one of the corners. The clicking becomes louder and faster as the car goes faster. Once I press the brakes the sound goes away. I didnt replace the rotors. Is that causing the problems? Anyone else encounter this problem? Any ideas?
