All, I am in the middle (Fronts are done) of changing the brakes on my 2007 Expedition EL and have run into a problem. How in the world do you get the pads out of the caliper? There is a "shuttle" that I have yet to figure how to get off, that needs to be removed so I can slide the pads out.
I hope you've found your answer already, as your post is about a week or so old. But for everyone else who encounters this; there are two black plastic caps. Remove them and unscrew the 7 MM hex screws to release the housing. After removing the metal housing, pry the outer pad out and push the inner brake pad in.
