What are 'differential' brakes?

Some of Campag's new brakes are described as 'differential'. Are they
just twin-pivot calipers with a lighter front than back, or is there
more to it than that?

I think they impart d^2x/dt ;-)

Lighter back than front? I thought they supplied single pivots on the back,
on the grounds that they're lighter and don't need to work nearly so well.

Yes, dual pivot at the front, single pivot at the back. That's the
'difference'.

That's right, and also the brake pads don't have to be set so close to the
rims

Um, those would only be infinitessssssimal brakes, wouldn't they?
Shouldn't they be imparting some d^2x/dt^2 ?
