As always, good advice from everyone on the List.  After Googling lots of potential issues and watching a variety of YouTube videos, here's how I tried to fix the problem.

1.  Drove back and forth to try to unfreeze the brake.
2.  Tried to remove the rubber grommets and adjust the tension on the brake.  A Triad dual-axle trailer has drop-down axles which cover the access to the adjuster.  Good for the boat riding low on the trailer.  Bad for an easy brake fix.
3.  Bought a small ramp which is much easier than a jack if you have a dual-axle.  Drive one tire up on the ramp and the other slightly lifts off of the ground.  I removed the tire and carefully yet forcefully banged on the drum near the brake pads.
4.  Called a friend who owned a trailer company.  Obviously should have done that from the start.
5.  Removed the drum.  The brake pads were de-laminated.  For the extra money it was worth it to buy the entire 10 x 2.25 single servo hydraulic brake assembly.  Problem solved.

Thanks for all your help!
