Im running into dead ends in my research. I'm trying to find the size of the 2003 - 2005 Aviator and the size of the 2006 - 2010 Explorer front rotors. I want to make sure that the 06-10 Explorers didn't get the 03-05 Aviator brakes from the factory seeing how they came later. My Explorer brakes have been getting stress and heat fractures on the rotors so I know they have been overheating so I would like to upgrade the diameter if possible. I DD my Explorer in heavy stop and go so its more of a safety upgrade. The stock set up is lacking to say the least. I realize I may need to swap the entire 4x4 spindle off of the Aviator and get Aviator calipers, its not my first brake swap. I'm just hitting some dead ends in my research.
