No, it doesn't. I think the rear calipers are the same, but the fronts
were "from" the 1992-96 100/A6: single-piston.

Not clear. The A4 calipers appear to have a greater swept area than
the G60s (larger diameter rotors).

I don't think so. There's a single line to each caliper. You may be
thinking of the rubber hose sections, though: there are two rubber
hoses in each of the single lines to each caliper...
