R1 concepts says the Edge has 316mm rotors both ends, I have yet to see a Edge with vented rear rotors, but the Edge Sport might. Big thing is whether they have cable E brakes, or electric like the Fusion. That was all dependent on what year also, Fusions 13 n up are all electric E bakes, but Ford seemed to lag behind on the SUV platforms going to it, but I want to say Edges got it in 2016, and same with the MKX. I keep hoping the get a 16 up Edge Sport in at work so I can look it over and get and idea of what they did with the brakes. I read where they had some with vented rotors on the back, but have yet to see one. If they did indeed make them with vented rotors, that would be a awesome brake upgrade for our carsSkipe, what was the difference with the rear brakes? I might have missed a thread on it but are they larger/thicker/vented?
