So I recently re-packed all the bearings with grease on my trailer. I towed it for 10 miles and felt the rear axle w/ brakes and the hubs were pretty hot. The brake axle both had hot hubs and the other was fine. I really don't think its a bearing issue but a brake issue. I think the brakes are dragging. The trailer is a 2001 Extreme for a tige 21ft, dual axle, leaf springs, bearing buddy.
What are the main causes for brakes sticking and how can I easily fix it? I only have 1 day to fix it then leaving for a lake trip. I will be towing with a F350 diesel so my last resort would be to disconnect the brakes. What is the best way to do that also?
