2002 Ford Excursion 7.3 4x4 rear brakes getting smoking hot. Noticed it on driver side first. Assumed the rotor was sticking, replaced it and the hose. Relaxed pads and found the pads on passenger side worn completely out as well. Test drove it 2 miles, both rear wheels smoking. Changed center brake hose, seemed to fx issue until my wife drove it to school to pick up kids. Both back wheels smoking. Is this an ABS Control Module?

Possibly the hand brakes dragging.
With a normal handbrake, you can remove some screws around the handbrake covering. The screws are sometimes well hidden so you have to look around.
When you get the covering off, there are two adjusting nuts at the rear of the handbrake. Turn the nuts until you can get "5 clicks" on the handbrake to set the brakes.
Some jack up the car while doing this so they can rotate the wheels by hand to feel when the brakes touch the pads.
Hope this helps

There are a number of issues that can cause overheating disc brakes. Disc brakes, when released, separate from the disc by the action of the rotor moving between them (since no rotor is perfectly true, there is a small about of wobble and it pushes the pads away from the rotor surface). Things that can cause this to go wrong are:

1. Caliper pistons that have rust rings that cause sticking. This most often will happen right after or shortly after replacing old, work out pads with new ones. Because the caliper piston was extended out farther with the worn pads, its surface may get rusty. This rust can cause sticking when the piston is pushed back into the bore with the new, thicker pads.
2. Caliper slide bolts will rust and get sticky, not allowing the caliper to release properly and re-center itself on the rotor. What you often see here is that one pad (inner or outer) is totally worn out and the other seems normal.
3. Rusty brake lines/caliper internals can cause restrictions in the flow of brake fluid and hold pressure after the brake pedal is released.
