Make sure you are getting power to the blue wire on your trailer when you put your tow vehicle in reverse. If you are then your solenoid is bad or the wire to it is broken. If no power to the blue wire, check reverse light fuse on tow vehicle.

BTW, You can use a "C" clamp to stop the tongue from compressing. Or something placed in the gap where the pin slides.
I'm saying this cause I didn't know these things and I unhooked the break line and now I'd have to rework the whole break system to get the breaks back. http://www.bassboatcentral.com/smileys/thumbsup2.gif
Re: Brakes locking up (gizzardshad)
Could be a faulty solenoid in the actuator.
