Check the inside surface of your rotors. If your caliper pins were not greased properly in the past, you will get excessive force on your inside disk pad/rotor surface and it will really messed it up. Going fast, this surface rubs slightly on your pads and will sing, especially while turning. I am currently dealing with the same issue. I just learned that there is a special grease for the caliper pins. If I depress the brake pedal ever-so-lightly, as I approach a stop, I can hear the irregularities of the rotor surface rubbing on the disk brakes. In a couple of weeks, I plan on redoing my front brakes to see if the noise goes away. I just did my right front hub assembly and was shocked when I saw the inside surface of my brake rotor.
