There has been discussion on other threads about the 14 bolt axle that hubs and brakes (much more modern) are more or less interchangeable with the old Eaton axles as well.
I do not recall the details or troubles but I do remember it being more or less possible with not a lot of effort.

So if you want even newer brakes- then those on a 14 bolt are sure something to look into.
