Good evening, I am hoping someone here can help. I have been chasing a brake groan for almost a year. I replaced front pads and rotors after my purchase, I tried two brands of aftermarket and just now put on motorcraft. Still no change. It's been to ford but they can't figure it out. Seems to mostly be left front, the goan started very intermittent, then progressively got worse. Now it will sometime do it without hitting the brakes! If I turn left the noise goes away. No it's not wheel bearing noise. I am a service manager at a local shop and my guys are convinced it's a pad/rotor transfer goan. Any help would be appreciated.
