Little help Hyundai trailer how do you slide tandems

Say what?
No button to pull?
Pictures?

 

You must set tractor brakes only,then walk to trailer to push button on slide to release pins then slide to hole you marked and pull trailer brake on walk back to ck. for all 4 pins in their holes

 

It's magic driva!

 

Trailer brakes set...releasing the brakes releases the pins to lock.

Some air release trailers I have pulled have a knob facing down that is behind the slider carriage that pushes in (or up) to retract the pins, and pull out to set the pins.

 

there’s a button somewhere, you have to get under there and find it. you also must leave the trailer brakes on via the red knob. otherwise the pins will not release. ive not pulled a hyundai trailer but the air lock buttons on our trailers are at the front of the axle set near where the manual handles are.
