I didn't find Huck brakes to be a problem or difficult in any way. They're similar enough to Bendix brakes not to be difficult to work on for anyone familiar with the latter. They're just a little different.
The only thing I don't like very much is the wheel cylinder that has to be trussed up like a Christmas ham while you're working on it.
Other than that, how often do you have to mess with them once they're installed? They have to be adjusted just ike Bendix brakes do after driving a few thousand miles.
