Hi,
Getting ready to drive 1000 miles and noticed in past couple of days (only with windows open and driving below 35mph-- or at least can only hear it then) an erratic metal on metal screech. It comes and goes away by itself, however the frequency seems to more often than say 2 weeks ago. I have shifted into neutral while it happens (coasting) but no difference, I have yanked on hand brake thinking e-brake caliper might be hanging, no difference. I have tried breaking aggressively and it didn't change. I only notice the sound driving straight and best if there is a wall or something next to the road that augments the sound. It comes and goes intermittently and bugging me. Could this be wheel bearing? Front pads are fine but cannot confirm if one of the front calipers has a stuck piston-- but if that was the case and pads are fine I didn't think it would have a metal on metal type sound. Welcome your thoughts or what I can do to eliminate possible culprits! Nothing like heading for a road-trip with 2 kayaks on the roof and wife and a screech (no I didn't mean my wife...hah! I should add that the frequency of the sound does not change with speed-- it remains the same if let is coast and reduce speed.
Thanks, Ed
