Thanks David for the link.
The brakes there have a different actuator arm than the perrot style "universal" that is on my car.
I think the principle is still the same that there needs to be a certain distance from the centre line of the kingpin to the pivot/cam centre. I am not sure how to achieve that with this style of brake.
The cause seems to be in the hinge action of the universal that causes the cam to turn slightly with the steering action. Even with biasing the cam back slightly on the splines it would still get adjusted out when the cable is adjusted for the correct shoe clearances. Still wondering!
