First of all, do you have an aircraft with a problem?

If so, exactly what have you done to troubleshoot it?

I’m not going to deal with hypothetical problems.

This is a engineering level issue. I will not be able to answer your question.

I'm not suggesting anything.
I have no clue why Boeing puts certain items in their manuals and excludes others.

I don't know why certain equipment links are not included in Boeing manuals.

As previously stated, either the system works or it doesn't.
If you're wearing tires unevenly.... it doesn't work.
The Fault Isolation Manual should be consulted as to what area might be causing you problems.
Any one of the areas you listed could be causing issues.
The "BIT" or Built In Test on the front of the unit would be the first place to go.

I'm sorry, I can't help you.
I neither work on 777's, nor would I be at liberty to supply any related manuals.

All internal box functions are set in the shop. There are no adjustments for line maintenance.

DC power is supplied from three transformer rectifiers.

You can measure voltage at any breaker downstream from each unit. The distribution schematics will give you guidance on how your aircraft is wired.

No. If maintenance does their job right. There’s no degradation, only failures of components. Once the fault has been identified and repaired, the system is 100% functional.

If things are failing, you get flat and blown tires.

Anti-Skid does exactly what its name states. It keeps the tires from skidding. All wheel speeds are monitored. If one has a wheel speed less that the others, it would be treated as a skid and the hydraulic pressure to that brake is reduced (or stopped) until the wheel speeds back up.

Pilots still apply brake pressure as they see fit. The Anti-Skid works without any input from them at all. On a 767 there is no Anti-Skid switch in the cockpit. It's always on.

If the aircraft has Auto-Brakes, it does everything and (not a good idea) the pilots wouldn't have to have their feet on the peddles at all.
