Ok so I am looking for some help here. I have a 2006 MS6 and I have put 4 rotors on the drive rear side already. I have changed pads and a caliper too. Why would they warp so fast? After a highway drive the left side is so hot you cant touch it, while the other side is not bad at all. It sounds like there is a spot in the rotor where it makes a sound every revolution too. There is not a chance all these rotors are bad, several different brands too. Try another caliper? E brake hanging up? Another thing is while driving and lightly applying pressure they make a high pitch sqeel until fully depressed. Hope somebody can help. It is driving me CRAZY!!!
