This was the typical Volvo brake setup for a long time, turbo or not. I don't
know what, if anything, changed when they started added ABS, though.

The main reason was that their dual-brake circuit setup put *three* wheels
in each: the fronts were on *both* indepdendent circuits along with one rear
wheel. The two pairs of pistons in the front calipers were isolated from
each other.

Most cars, including Audi, were content with a diagonal split, with
one front and one rear on each circuit.

Again, I think the introduction of ABS may have changed a lot of this, since
it would require an additional set of channels through the ABS pressure
regulator to allow two independent circuits to each front wheel...
