A month ago I bought a new dual axles dump trailer with GVWR of #7000. The problem I am having since I took delivery of it is that the driver side front tire of the trailer keep on locking up when braking (unloaded and fully loaded). It would not start to lock up until I slowed down to around 15-20 MPH and less.
I thought that my Jordan Ultima 2020 controller was set too high (3.0A) so I set it at lower amperage, but still the same problem. I turned the amperage setting down to 1.5A and it still locks up (unloaded). Think about it, both axles has brakes, so that mean four magnets, do the math. That is around 0.4A for each magnet if they are working correctly. When fully loaded, I had the controller set to 3.5A and it would lock up too.
With the setting at 1.5A unloaded and 3.5A loaded, I feel that it is not sufficient because my truck is taking longer distance and time to brake. Something is definitely wrong with the driver side front tire of the trailer. Shortly after I took delivery of it, I told my dealer about it, he said to bring it in and they said they set the brake tension (something like that) back a bit. They said that it would not break in until I get around 25 miles on it or after it get a real full load. Well... I have put at least 250 miles on it so far and has loaded it fully twice, with several other loads at smaller scale. I am going to contact my dealer again, but first I would like to know what would be the approminately amperage setting for four brakes (two axles) when empty and fully loaded? Thanks!
