2012 GE8 making a harmonic sound on a non frequent basis. At first I thought it might be A/C related because it would quite stop when the A/C button was off. But I haven’t had the A/C off for a long drive so not sure. The first oil change I got (just purchased a week ago) the tech at Honda told me I was at the min line for brake fluid. I noted that

I got the front brake pads replaced as well as brake flush/fluid exchange. Afterwards sound seemed to simmer down and be less frequent. So I plan to do the rear drums next and hope (fingers crossed) the sound goes away?

has anyone had this issue? If I had to describe it it sounds like the noise that happens when you take a wet finger on the rim of a wine glass. That’s the pitch noise it makes. I would post a video here but don’t know how to shrink the file.

thanks for any help!
