The centreline of the swept area is also further from the axis, giving
the braking force greater moment.  Its circumference is also greater,
giving a greater average pad/disc speed for a given radial velocity -
helping the pads reach working temperature much faster.

The difference in braking power between Galvin's 200TQ (pre-UFO) and
his V8Q was phenomenal.
