Why go for more brake pots/cylinders
A popular brake upgrade is to a caliper with more pots, The reason is that more pots enables the caliper designer to spread the braking force evenly over a larger pad. A larger pad has more friction area and is thereby more effective at stopping the vehicle.
This is true up to a point. It is quite logical that a pad has a height as well as its width and given a specific pad size it will be more effective to arrange 3 pots to spread an even load than say 5 or 6.. see diagram
