The rotor is set up really straight... it is inline with the non moving pad pefectly.. soo the rotor does not move or flex at all. I have replaced the cable... but nothing, and the arm thing isnt bottoming out... like when it goes in to far n stops. To my knowledge.. its set up really well, it worked well before, nothing has changed much.. its just re-tiring, and i dont like it. Its only 2months old... help....
