Trailer Brakes Do I need it ?

[nymack66]

I am posting this under modification because its exactly what I am thinking on doing. My Trailer Brakes are locking up again on a different hub this time.
The last time this happened the dealership replaced the entire hub/caliper hoses etc all under warranty.
When I cam back home from Boating last week it was so hot it was melting the grease and slinging it around the rim, what a mess ...
I am seriously thinking on removing all four disc brakes, I rinse and wash this crap and yet it acts up on me.
My fear is it will lock up, overheat the hub/rim and explode my tires and create havoc on the HWY.
My old trailer which was also a double axle no brakes was easier to haul.
Any DOT regulations I need to worry about? or I am doing something wrong?
