If you could not see any brake fluid in the reservoir, then it went somewhere and there is a leak. Perhaps check to see if it leaked out of the master cylinder into the brake booster?
Bob is correct. You have a leak. The hard pedal with the engine off is normal because there's no vacuum assist with the engine off. HTH. -Jim
