On my Bav it turned out to be a leaky clutch slave cylinder.
Ummm- automatic or manual?
as i assume that you have checked the common places, this is the floor under the four calipers, under the clutch slave cyl, and under the rear brake proportioning valve, so lets talk about unusual places,
brake pump onto vaccum booster, you can experience leaks between the two of these parts, and you will not see it, as the fluid is going into the booster, impossible to check without opening the booster
clutch master cyl onto the firewall inner under pedals area, if the clutch master is leaking, you will have the leak under your feet, check the pedal wall

Since your car is an automatic, my money is on the brake master leaking out the back into the booster. I had this leak in a csa many years ago.

Brake fluid leakage
I tend to agree with JMinNJ and a certain sign of fluid leakage in the brake servo(s) is white smoke from the exhaust after heavy braking from a fully warmed-up engine as fluid gets drawn by vacuum into the intake. If this is the case, it will get progressively worse but may take some time before it is enough to be noticed in the rear view mirror. Best wishes, John.

Flexible hose to master cylinders
Mine was leaking from the clutch slave cylinder and also the reservoir to master cylinders, the pipe goes porous and weeps. Worth a look as it is a cheap fix.

We can talk and talk, but it's time for the OP to reveal what was causing the brake system to (ahem) lose (ahem) fluid.
Back atcha, OP.

Loosee, you got some 'splainin to do...
I did some inspecting and cleaning over the weekend. Looked at all the suggested including inside at the brake pedal. Only place I found is what looks like fluid at the MC where the lines from the reservoir connects. Attached a picture. Sorry pictures upside down. I'm going to replace the rubber fitting if they are available and see if this fixes the problem.

your setup is horribly tensioned, see the rear pipe, you must correct the tension, i auggest new hoses too, use the correct type !
Looks like it's leaking through the hoses from the resevoir to the master cylinder. It's a cheap and easy job to replace these.
i think that your tension is due to wrong lenght of the hoses, they seem to be too short so they pull the pipe out of its normal place
This is what I used (blue):
