    Default trailor wheel lockup when revercing

    i checked the bearings and set the braking system ,used the alko manual to adjust.

    i tried to reverce but the bakkie had struggled to reverce the trailor ,then first i sumulated the braking action and wedged the shaft and when trying to push back the trailor it only released on the one wheel .

    i jacked up the trailor and simulated the brake action by wedging the shaft again in the brake position ,now i turned the left wheel backwards and it released ,but the right wheel did'nt .

    so i removed the wheel and hub ,but could'nt see anything wrong ,i am thinking that i had adjusted that wheel too much that the switch over action does'nt have time to release , am i correct or has anyone had the same problem and solved it

    Don't forget you must go forward a bit before reversing to click the brake off.
    There is no task too simple for some people to complicate !

    Just back it off a bit more, it is a little bit different to setting vehicle break shoes.

    If you set them to tight, it will start to brake when ever you slow down or use the vehicles brakes ever so slightly, this will cause the hubs to run hot, too hot.
    As I understand it, the trailer only really starts to brake if you brake with the vehicle, if that makes sense, the wheels of the trailer must run free at all times.

    You need to back off 10-15 clicks each side from locked, I prefer 15, make sure your balance bar on the cables are parallel to the axle. You should also make sure that there is 10-12mm play between the piston rod and the brake lever at the coupler.

    the moment you start to go forward the spring that holds the auto reverse brings it back to its original position .

    just went and adjusted the problem brake as you mentioned ,simulated by putting a makeshift block to brake the trailor ,reverced the wheel and it is ok now,,now both are doing what it should be doing . and yes the balancing bar has to be parallel and the gap at the piston rod.

    now i would like to know why didn't the manual writers mentioned that it could't be done that way allso ,i mean ,jack up the trailor ,simulate the braking action ,turn the wheel in reverce ,done as easy as that .

    the trick here is understanding how the whole system works ,then it is easy to tackle the job.
