Are you sure it isn't just the long pedal travel that blurs the
impression? Alfa 75 uses a relatively small diameter master
cylinder, making pedal travel longer, but also ensuring that you
can build up a higher pressure and making it easier to control the
brake pressure accurately.

Testing the brakes should be pretty easy. With the engine off,
pump the brake pedal 5-6 times and keep the pressure on the pedal.
No matter how hard you press the pedal, it must not sink towards
the floor. With the pedal still pressed, you start the engine. Now
the pedal should sink a bit, as the brake servo kicks in, but
still, the pedal should end up stationary and not keep dropping
towards the floor. Build up some speed, 50 kmh/35 mph or so and
try stopping the car without touching the steering wheel. If the
road is nice and level, the car should stop in a straight line, if
not, make a U-turn and see if the car pulls to the other side when
braking again. Finally, see if the brakes can lock the wheels and
the car still goes straight. If all that checks out, your brakes
should be okay..

I say it isn't a flaw, it's a force..
