One other thing, just in case, make sure you check the rear brake plunger (the rod) make sure it is not set up to high, sometimes when the rotors get hot and expand they will move closer to the pads thus less throw if any required on the rear brake. so if you are downshifting hard and on the rear brake even a little bit , it might only take a wee touch to lock those suckers up......ask me how i know this :-)
