Much the same result can be obtained more subtly by making the FF32 bridge plate in thicker alloy, say 1/4" with milled pockets for the padbolt nuts and then making a revised F56 bush in a top hat form. Then you only have to rid yourself of flexure and lost motion in the handlebar lever and perch, the long cable, the cam sleeve, the brake plates, pivot pins and the shoes. Then, for a brief and happy moment you will have brakes as good as the 1950 road test! The Vincent pages of the Britbike Forum cover this as well.
