Ahh so they do step out ! im sure thats where the varied answers has come from.

So 40.44mm is the go then

So the od on the outter most part is 37, and the bit behind the boot is 40.44?

Cool cos I just took some shots of mine with the calipers and the outside is definatly not 40.44mm!

SO when going for engineering, do they take the 'pot size' for braking force (or whatever) from the exposed part or the larger inside part?
