Have a twin axle trailer.
Each year service hubs ... wash out all grease, repack, new seals, clean
drums etc. Adjust brakes
The reverse override link & spring are not removed during service (AlKo
instructions)

The brakes are AlKo auto reverse type.
Going fwd brakes work fine, stationary handbrakes applies and holds.

In reverse after a short distance (presume until hitch damper completes
travel) the brakes lock on.
If I unhook trailer and manoeuvre by hand it will reverse with no issue
..... so only a problem when push rod activates.

Any suggestions ?
