My 4 wheel ifor williams trailer drives perfectly OK forwards, and
when fully loaded.

Seems to be OK when reversing with no load.

But as soon as I get some weight in the trailer and try to reverse the
trailer brakes come on.

Any idea of what the problem is, and is there an easy fix at the
roadside. As I do not want to get caught out.

is it an auto reverse coupling?, often you need to engage a peg or lever to
reverse with any load on (empty there may not be enough sticktion to engage
the brakes)

Certainly should be - they've been mandatory for bloody _ages_. <quick

Sorry, 1989. Slightly less pre-historic, but still...

It's common for an empty trailer to start moving in reverse without the
reversing clip in place. What happens is that when empty the spring does not
compress enough to engage the brakes before it starts to move. The brakes
are quite possibly also not being used when going forwards, at least at low
speeds when unladen.
