Trailer Brakes
 

I have a eagle 2004 46' trailer that was converted from surge brake to electric/hydraulic brakes.

I had a brake and bearing job done last year, and the trailer stopped great.

Last week, the controller started acting up, and I am not sure what is the cause. When I hit the brakes, they slowly apply 100% and won't let go for a few seconds. This happens no matter what I have the gain set on (1-10) I have a Ford F350 with the built in controller.

The brake controller on the trailer is mounted on the tongue next to the jack. It is rectangualr shaped, a little bigger than a shoe box. One side of it is the electric componet, the other holds the brake fluid. I will post a pic to try to identify the model. I want to troubleshoot the problem.

Any help is appreciated.

when you back the trailer in the water and hit the brakes, it wreakes havok on the electronics, the trailer magnets. Thats why boat trailers come with surge brakes

He is referring to an electric over hydraulic brake system. Nothing electric goes in the water. There are no magnets.

electric brakes
 

I switched to eletric brakes 2 years ago from hydr. drum . the best thing I ever did . I have a 29 fountain , it stops good . I never ever unplug the trailer. Tim

Sounds like it maybe a Carliel system but I would try a different truck first that has a controller in it.
