It was those dang black rotors that was the problem. The white ones that replaced the black rotors were much more reliable. Other colors have been used over the years but not black because of the reputation for burn through the original rotors had. Recently I have noticed a manufacturer that is using the color black for their hei rotors. I think either they are unaware of the reputation black rotors had or they figure it has been long enough that no one remembers. I had to laugh a little when I removed the cap and saw the black rotor.
