       The problem is your master cylinder is leaking fluid into the brake 
booster which in turn is being sucked out thru that hose you found the 
wetness in and into the engine to be burned, thus the white smoke.
       You need to rebuild or replace the master cylinder to stop the leak.
       You also need to remove all the brake fluid from the inside of the 
brake booster ASAP!  The fluid will deteriorate the rubber diaphragm in the 
booster and cause it to fail which will cost you many more $$$$'s.
       The fluid can be removed with a turkey baster or whatever after the 
master cylinder is removed.  Just make sure to get it all out.
