Slightly off topic but , the big daddy of drum breaks
an double sided 8 LS front brake . Pretty certain designed by Dave Degens and a company called CMA to combat brake fade.
Saw this brake hanging up on a stand at the motor cycle show when it was at Earls court , paid £80 for it if I recall. Had it laced into a 19" rime and put iton a Triton I had.
went out about 4 times , tried to dial it in and ended up on my arze down the road with a bad case of gravel rash. Never bothered with it after that. considered it a brake from hell
some years later I found out that the brake shoe linings were AM4 (?) Green linings , def' not for high way use
only for competion / road racing as they had to be warmed up gradually and the heat maintained , which would happen on circuit racing
still live and learn. Incidentally if you could actually track one of these brakes down , u would not see much change (if any) out of 2 grand
still got the brake as well
