As a matter of interest does anyone know just what ci drums are made of generally? Minimum strength ordinary cast iron hardly seems appropriate.
Most claim superior friction, quite apart from avoidance of distortion. It seems strange that ci full of carbon should be better than steel. CI drums have often been oil soaked. Does this permanently reduce friction?
I suppose such cars are now rare in the UK but many older small and medium jap cars semed to have rear drums about 7 inches. Brake specialiats would likely be able to suggest candidates.
