Can anyone say what the differences are between the front and rear brake rotor on a 2002 F250 super duty 4x4? I put the rotors next to each other today and couldn't spot a difference by visual inspection.

Was the rear one you looked at the driver or passenger side?
I thought the E-brake drum was on the drivers side.

The difference is night and day. The diameter is different, thickness, brake pad swept surface and the rear rotors have a drum for the parking brake.
Hope this detailed reply (with photos) is useful to anyone else searching and wondering if you can use a rear rotor on the front in a pinch (no, you cannot).
Summary of differences: Front Rotor:
Disc Thickness (mm) 36
Outside Diameter (mm) 331
I really don't want to be that person.......
What exactly happened there? It looks like the broken rotor has zero wear on it (but has had a wheel mounted to it) and has multiple other cracks in the hat area by each stud, but just not as bad. A little more info here would help others from being that person, is this the result of a rear rotor being mounted up front?

Correct. This is the result of working on a vehicle at 1am without adequate sleep the night before, and trying to get it together ASAP.
Slow down, check fitment before cinching bolts down.
Luckily the issue was felt driving right out of the driveway the night before, so it came right back to the shop and went on jackstands for the next day. I hadn't got 100 ft up the road when felt something wasn't right with the install.
Even though the rotors look similar, the front is actually 5mm thicker, and the height of the overall part is also several mm higher. The company I bought the next set of rotors did happen to have their labeled front/rear, but I'd learned my lesson and carefully measured everything before installing yesterday.
I said that I was doing the job on low sleep at 1 in the morning while it was raining, trying to get it done fast. I'd never done rear brakes on this truck, so i didn't know to instantly look for the 1mm difference in overall rotor height.
FRONT ROTOR: front rotor
REAR ROTOR:
REAR ROTOR
I posted this with grace, hoping to alert others to be careful and take time to ensure proper fit before reaching for the impact driver. I've not made a boneheaded mistake like this since I was a teenager. I feel pretty dumb, but those are the "brakes".
What kind of Rotors and Calipers did you use? Did you change the brake lines? I've never done a brake job on my 2002 F 250 CC XLT, but at 56 I'm gonna try it. I know that if you change Calipers you have to bleed the brakes. I would like to at least change the rotors out and the brake pads. Was it a quality rotor and caliper you used?
I've noticed some brake fluid coming out by the sensor and I'm ordering a new one (master cylinder) from FORD but Covid has back ordered some key items.
What's the step by step process for bleeding the brakes? I know when I get the master cylinder, I would bench bleed the cylinder. Any wisdom would be greatly appreciated of the overall brake job.
