Fill the brake fluid reservoir with brake fluid, get a friend to apply pressure to the brake pedal while you look for the source of the leak. Look at each wheel, look at the brake flexible rubber hoses out at each wheel. Look at the brake metal lines, if you don't see a leak the rear seal in the master cylinder may be bad and the brake fluid is leaking into the brake booster.
