I have a 2015 Skeeter trailer made by EZ LOADER. I couldn't get the brakes too bleed so after looking around I figured it out. The main brake line running down the starboard side of the trailer runs through metal rings. These rings are supposed to have rubber grommets installed to protect the brake line from chaffing through. Well guess who's trailer left the factory without the grommets installed.....So my brake line chaffed though in several spots where it made contact with the metal rings. So I would check and make sure your brake line is properly secured and the grommets where used.
