Hey guys Just in need of some advise on what my issue may be. Today, driving on the highway, cruise control set at 110km. I get this faint noise, kind of like a helicopter type of "whoo ,whoo, whoo". Only quiet but gradually got louder over about 30 seconds. No noticeable pulling or dragging. So I give the brake pedal a quick stab to try isolate it and it goes away. It came back twice again during my 180km trip. Hard to pick where the noise was coming from. Sounds like a wheel out of balance kinda, and sends a minor vibration through the car. But always goes away with a quick touch on the brakes Any body experienced this? I got a theory that it may be rotors warped and allowing the pad to begin to fall over and just touch the rotor, but that is just the first thing that came to mind. Front rotors are fairly worn, pads have done about 5000kms, rears I've never touched since I've had it and look to be in good working order. 4 & 1 brembos.
