    What is your truck? Year, make, ect. What is you control. Some of them, when set right, show 0.0 unless you are slowing down.
    Do the brakes work off the hand slide?

    Like the previous poster said, check your trailer brakes with the manual slide. Also just have someone stand by your trailer wheels while you press the brake pedal in your truck. If the trailer brakes are working they should here the calipers.

    Did you circuit test your plug for the pin that controls your trailer brakes? Generally the blue wire is your electric brake pin.

    if the brake's in fact will not stop the trailer off the brake pedal ,and will off the hand actuator then one side of your controller may be burned out ! jack up the trailer and try the control buy hand and then foot brake operation to verify . :waving:

    You never said if the brakes work off the slide.

    If they do, check & see if your 3rd brake light works. It is what tells your control to work. Look for a fuse marked "CHMSL", it will be under the hood or on the side of the dash.

    I dont have any trailers with brakes on them becuase all of mine are too small for them, but i have always heard that you need to make sure the electric brakes are ajusted right. Its possible that you just need to adjust the brakes on each axle.

    you could be losing the ground on the magnet's ,check the wires on the magnets there are two on each,one is ground ,one is 12vt your loosing either,prob the voltage signal ,check the plug on the truck then the magnet's ,even check the ground between the truck and trailer . :confused:
