have a look in the servo you should be able to pull master cylinder away enough to check

could be 1 of the joints weeping or wheel cylinders/calibers weeping. and doubt you would get a drip on pavement. more like a wet spot around the area where the leak is. Needs a total inspection, requiring tyre removal for a proper look see

If the seals in the master cylinder are leaking the fluid will go straight past them, but to loose fluid from the cylinder it has to go somewhere -

if no trace of leak at any join - it is prolly the servo drinking it ...

Any fluid on the pedal or carpet inside of the vehicle under the pedal box ? ...
