Thanks for the help, I totally forgot about this as my brother just had someone else haul the dozer the rest of the way and haven't needed the trailer again. Had a close look at things you guys mentioned and everything looked good (didn't pull the line off the brake pod though) greased it all again and hooked up, locked up the brakes a half dozen or so times each one released perfectly and no issues after loading hoe and coming back, hub was same temp as other wheels. I always attach the glad hands on the trailer after unhooking to keep dirt out.
