I have a 2004 Stratos, single axle trailer with surge brakes. I live 20 minutes from the lake, 45-55 MPH and a few stops, when I got there today both brakes were over heated and smoking. I let the brakes cool down, launched the boat and looked at the brakes, lines and didn't see anything wrong, reservoir was full. For the trip home, I opened the bleeder screws (it's a short trip and my 18ft doesn't even require trailer brakes as it was an option.) What does everyone think, brakes didn't release? What should I replace? I will pull the bearings and inspect them (regrease) and replace the brake pads.
