What's so wrong that it must go away?
Chocks are fun when you need to maneuver the trailer on a not-so-level surface. Done that.
Recently saw weather move chocked trailers around in the tiedowns. Several were damaged. One punched a hole in the hangar that stopped it.
Electric brakes with the parking brake option may be fine when the whole package is in tune and present, but useless if towed behind a car without the right controller.
Believe Dexter now has hydraulic brake axles with a parking brake option. Perhaps not as easy to set up as the mechanical ones, but far less vehicle-dependent than electric.
Do AlKo axles for Spindelberger Cobra trailers fit Anschau Komet trailers? Believe Wings and Wheels has some of those in stock.
Otherwise, perhaps it just needs new brake shoes, drums resurfacing or replacing, and set up properly. While you're at it replace the bearings.
