ABS Locked up
For checking moisture content:
You find the ABS unit?
The earliest ABS units were ill designed and once locked up are toast. However, the stand brake system should still function. The whole system may need a overhaul.
What fluid does the master cap say. Can only use DOT 3 or 4 in ABS. All other Harley's of that year use DOT5. You can't mix them. If someone has, it's all needs rebuilt.
This can get you killed or worst. You need a real expert here. Good luck since you have a rare Harley.

Post a picture of the actual motorcycle you are asking about if this picture is just one taken from the internet.

I was also under the impression that when HD introduced ABS in 2005, they switched all bikes back to DOT 3/4 brake fluid from the DOT 5 previously used, to avoid any possible confusion and/or problems.... I won't swear to this part, my memory isn't what it used to be...

OP, as mentioned, your pic doesn't show OEM front forks... You most likely have a custom front end/ ABS brake setup on that bike... It could be retrofitted HD parts form a subsequent year, or......??
IMHO, it will hard to give any good guess about your issue, without knowing what you actually have installed on that bike...

I vote it`s just a caliper problem on a non-abs bike
