E450 Braking Improvement with Axle Upgrade
Earlier this year I replaced the OEM axle, brakes, and radius arms on our 2002 chassis with a new takeoff axle from a 2012 E450. The 4x4 conversion companies will sell these parts as a "kit." We've...

wcj - I changed only the Front Axle. I don't believe the 4x4 upfitters change the rear axle, brakes, etc.
ramble - Another OP may have some numbers, I do not. I can say the "new" rotors are simply bigger. There is more swept area from the hub area outward to a larger overall diameter. The "platters" on each side of the "waffle" on between them are thicker, and the Hub/Disc assembly is significantly heavier. Pads are wider to touch the larger swept surface, plus longer, and I believe a little thicker. Likewise, the calipers are noticeably larger.
From what I've read, the rear brakes were also upgraded on the E450 for 2008 and later. Larger, and possibly mounted differently. E350 with rear disc had slide bolt mounts and E450 used driven-in slide clips. I'd imagine the newer ones have larger brakes with slide bolts.
EDIT: Ford describes the 2008 braking system as "all new" so I guess I went "half new." Part of the "new" story was different Pad Material.
