Any info on how to work on these brakes?
The best source for specific service info is usually the maker's site.

Or you can, search for tutotials on the same job ie. adjust bicycle disc brakes and fine one for the same general type of brake, such as mechanical vs. hydraulic.

Odds are your adjuster is frozen either because it was threaded to one end hard against the stop, or corrosion on the threads. Some force may be needed to free it, but first you have to determine which way to turn.
