Just to ensure the details of my set up are known. Enfield handlebar lever with built in 'wiffle tree'. No balance beam but that replaced by two solid pieces of ali bar, bolted to the bridge plate. The adjusters are screwed in to these bars. Single cable each side all the way from the handlebar lever to the brake arms. I made my own cables from very sturdy inners and outers and there is no play. The handlebar lever just comes up to a stop. Whether they would be good enough for racing is a different matter.
