We recently bought a new Dodge Grand Caravan. It has 17" wheels and I noticed the brake disks pretty much filled the entire wheel space. So I looked up the disk size and they are 13" disks with dual piston calipers all-round. It doesn't list the new disk thickness, but the discard thickness is just over an inch and they weigh 22lbs each. Pretty beefy brakes for a 3,800lb vehicle and yes they worked pretty good in the mountains in Mexico last week!
The GMC has 11" front disks... the larger the disk the more mechanical advantage the brakes have and the more swept disk area per revolution. The one-ton front end has 12.5" front disks.
Just an observation while sipping a margarita!
