I have a ranger Cherokee boat and a ranger trail trailor. I bought a yr ago and put new hubs and wheel bearings and bearing buddies. I drove from Pa. to Colorado. It was fine. It sat for a yr till got a house. We went fishing 4 times and the 5th time today I had to slam the breaks. Little down the road both wheels started smoking. It sat for 30 min it was still hot. All the greas was every . I drove 40 min home with little breaking. I got home put in garage and was all cool.i have breaks where when put on breaks the trailor moves forward and that’s how the breaks work. Was it just locked up and when cooled down ok. I’m going to take the wheels off and repack and look over. What should I be looking for .Thanks Jack
