No, I don't have a concrete answer what the root issue was, but I feel the fluid had some part in it. My original thoughts were master cylinder or fluid, because I could almost control the noise by how hard I pressed on the brake pedal. During the upgrade, I didn't do anything to the master cylinder, so I am thinking 100,000 miles on probably the original fluid might be the culprit.
Also, after I bought it, the front brakes would squeal a little when the brakes were hot. My mechanic checked it out and said everything was fine. The Owner's Manual said this might happen with V6s, but not to worry. That went away completely with the GT rotors and ceramic pads.
