Rotor and pads and bearings. Oh my!
Left rear brake disc (yes, rear disc) overheated last trip out to the point the brake fluid boiled and disc was smoking. Whether it was a sticking piston or internal kink in the final section of brak...

Not uncommon for rear disc brakes to stick. Fronts might have a little more trouble because of the steering effects on the hoses. Our E450 had the rear brakes repaired with "loaded calipers" which are rebuilt or new calipers with pads and hardware in place.
Does your brake setup look like this little image?
If it's close, then you'll have to pull the drive axle (eight fasteners at that little hub flange), dismantle the outer bearing, and slide the hub/rotor assembly off.
Then the rotor will be bolted to the back (inside) of the hub. It's probably meant to be turned (to true the surfaces) as an assembly. A new rotor would be torqued to the hub and then turned.
But YES, if the calipers stuck and got the rotors to 400*, the pads are (literally in this case...) toast.
If you can get rebuild kits, calipers are actually pretty easy. Unless you can't get slide parts without buying a rebuilt caliper, a seal kit and a new piston will make a new, albeit rusty, caliper.
