I decided not to take off the ebrake pads once I saw how they work, however, the noise is still there.
I made numerous adjustments to the breakes to see if anything changes, but so far no luck.
the ebrake never worked right for me to begin with, I think one of the lines might be broken, and I plan on replacing it soon.
I'm starting to think that this is related to the driveshaft, I had my felx discs replaced not long ago, perhaps something came loose.
All I know is that the noise is related to the speed of the car, I can't hear it below 20kmph, and above 70 it turns into a constant moan.
