I've been watchign here for a while and getting lots of great information. Now I have a question! I have a 21 foot Skeeter Baypro... and it's finally time to do some work on the trailer. The trailer needs new hubs, springs and shackles. I am thinking of adding trailer brakes while I am fixing ut up. What's better, the new disc brakes or the old style drum brakes? Keep in mind it has no brake system currently....
