I think bud was trying to say, if it was a 6 pot it would have 6 pots inside it, its just a excessively large 4 pot caliper chassis, not a bad thing, more surface area, better ventilation/dissipation of heat!
The thing with 6 pots are they need to be designed will, they should have a big single pot each side and 2 small pots either side of it, that way the 2 pots do the light even braking, but when the heavy braking hits the large pot pushes out to do the heavy work... Porsche ones really work well with that, other make I've seen dont use such methods and most have all the average sized pots 3 a side....
But as Jonyjay said, my porsche caliper pots are big chassised.. and the pots i have 1 pot very small and a very large pot...
