Hi folks:
I have a 2010 road runner tandem axle with hydraulic surge drum brakes. I do not have the fresh water flush system. I use it to carry my 21 trophy with outboards.

After about 8-10 times of use, the front port side brake was stuck on and I could not get the wheel to roll. After backing up and snapping it forward a few times it let go.This happened a couple more times and then I took it in and had it looked at. Nothing could be found but they did back the adjuster off and it was good for another 4-6 times.

The last time I used it it would not roll at all. I have a 3/4 ton diesel standard and I could not move it forward or back. I jacked it up to find both wheels stuck hard on the port side.The starboard side was free an normal.After checking fluid and brake lines I backed the adjusters all the way off and was able to get it rolling again. I disconnected the line from the surge cylinder and reservoir rendering the brakes useless. This got me home. I have been back to the mechanics and they are suggesting a change to disc brakes.

This is expensive to the tune of 13-15 hundred. I am wondering what experience and suggestions you all may have with this kind of problem. Any info would be much appreciated.

Thanks again (in advance) for your feedback.
