We might be braking all wheels, but we're using 1930's rod and drum brake technology. I'd be surprised if the overall braking efficiency was much better than the American style hydraulic operated discs all be it only on one axle.
Fade, I've found to be the biggest issue (that roundabout coming down into Oban !!!) more so than their absolute performance and that is a characteristic of drums. That, and constantly needing adjusted.
Hopefully in the future the technology might be allowed to move forward, freed of the current "type approval" costs and constraints.
(Although not a requirement I have seen US trailers with parking brakes)
