Hey, every since I changed my brake pads I have heard a wierd sound when cruising. Its kind of like a knocking sound and can happen no matter what speed I am traveling at. However when I apply pressure to the brakes it immediatly stops and wont start making the sound again until i realease the break. I checked the vibration pins and they look good, I dont seem to get this all the time when I drive my car and seems more often then not to happen after ive been driving for 15+ minutes.
Thanks in advance.
