Look for a suggestion ...
Have Indespension Super Roller Coaster 5.5 twin axle trailer.
Brakes are Al-Ko overrun brakes as on many UK trailers.
Braking & hand brake working fine.
But on reversing once the hydraulic hitch coupling comes to end of its travel it locks on the brakes ... they are not ‘tripping out’ the shoes via the auto reverse function. As I have a sloped drive - they lock on as soon as I try reversing up it.
If I disconnect from car ... I can pull trailer up drive fine with my winch ... so confirms the brakes are not app,Yong other than from road actuator, and Auto-reverse not tripping ... going backwards should force trailing shoe into cam and release the braking effect.
Checked adjustment of brakes 4 times, all seems fine.
The compensator bar where the 4 Bowden cables connect ... has a rod down to the ‘S pawl’ operating lever on hitch.
As rod adjuster was corroded.. replaced both adjuster and clevis assemly (both ends) ends and the 2 rods, set up for zero play.
Still the same ....
Apart from cleaning you don’t adjust (none possible anyway) the auto reverse cam & spring.
Anybody any suggestions,
