I am sorry for the long wait
so there is NO brake fluid leaks at all and the fluid is staying full in the reservoir ?
since the booster is just a vacuum assist if there was any kind of booster issue the brake pedal would just be very hard to push but usually would not cause the pedal to go to the floor
if you unbolt and slide the master cylinder forward off the booster is there brake fluid in the booster ? or out of the rear of the master cylinder ?
since that front was low again the brake fluid has to be going somewhere
pull the mater forward the odds are its leaking out the back of it and filling the booster with the brake fluid
if that is the case the master and booster needs to be changed
if you have any questions please ask as i do not get credit for my work until you rate us here at Justanswer
