Tony,
I checked as best I could and the angle machined on the brake camshaft is about 30 degrees, I have new linings and when applied the lever is still well forward of 90 degrees. This amount of angle moves the ball further away from the centre of rotation of the king pin. It would only ever reach this point if the brake linings were worn away and not shimmed to compensate.
Surely the ideal position for the lever ball viewed from the top would be perpendicular to the cable when the wheels are straight ahead.
I have adjusted my front cable quite tight at present so brakes are nearly applied, I can now turn the wheels lock to lock and the brakes do not affect the wheel rotation.(car is still on axle stands) does this sound ok?

Bob,
Surely if the cam can rotate to the point of jamming on it means the linings are so worn, or the end of the shoe is worn and should have new linings or shim added to the shoe?
One of my brake shoes was reluctant to return to the off position because a previous owner had used too wide a shim on the shoe so it jammed in the cam sides. If all is free surely they will always return to the correct position.
