I'm a little confused?
The Magic Tilt trailer comes with drum brakes so it is possible that they are locked up in only one direction, solution is to take the drum off clean the shoes and drum looking at the slave cylinder to make sure it doesn't bind and the springs are in good shape. The look at the surge actuator is free to move its full travel, normally you can activate it with a large screw driver through the top. The surge actuator is set up for a 2 inch ball only, partially activating the actuator should not have any effect on the size of the ball. My best suggestion would be to replace the whole braking system with disk brakes, that way you don't have the problem of corrosion locking them up. You can get the parts for the conversion at Northern Tools or any trailer parts place, don't forget to buy or modify the actuator for disk brakes. You can see what I did on my brakes in the photo forum under Hunter 260 LKYusnret. Hope this helps. Baums Rush
