From my memory of the post elsewhere, I was going to say it's a 9mm too!
The Allen wrench size IS a 9 mm.
I didn't need it though.
After looking at the caliper I realized all I had to do was remove the two 18 mm bolts and remove the whole caliper assembly.
With less than 9000 miles on my 2009 Escape the rotors were already seizing/rusting to the hub.
I removed the rotors and cleaned up the rusty surfaces and buttered them up with never seize....piece of cake.
