That hub can be repaired, carefully turn off the spoke flange and shrink an alloy or steel ones on.
I looked closely at these a few years ago when the new Brough Superior appeared at the motorcycle show and researched on the internet to see how they worked. I can see that it is a way to increase the braking area without increasing the diameter but other than that I saw it as an unnecessary complication and a bit of a gimmick. There are lots of incredibly good brakes available without the extra complication used here.In among the drivel one reads in bike papers was a nugget of interest about the new Brough Superior SS100.
Yes I know what's the market for a £60K bike with a nod to a 1930 design? (and this from a country with a 50mph limit on single carriageways)
Anyway tucked away in the specs was the front brake which is a 4 (yes 4) X230mm dia discs front on a cotton reel hub arranged on each end with 4 pot calipers, braking distances are not quoted on road tests nowadays, but the hack said they were "stupendously powerful " lets see 230mm is about 9 inches in real money OK I could live with 180 to keep the profile near the original 7" drum it said they were based on Aircraft brakes, not for use on Bramptons though methinks
According to the rag I read the SS100 is made in France and I know this year from the waves of boredom on the single carriageway to Dunkirk 80kph is a good as it gets. Any side road or farm track intersection and its less. Not a problem next year, I have no wish to join a queue for an international driving license to sample that pain again.I
Note: The speed limit on single carriageways in the UK is 60 mph unless otherwise posted not 50 mph as posted above.
