However, the game changed from the start of the second half as with the wind in their favour, Brady pressed hard for a goal. And after slick passing from Freddie Martin, Jamie Baum and Benjy Randall, Ben Barnett hit a well-placed shot into the corner to kickstart Brady's comeback.
Jacob Brand scored the equaliser in the closing stages of normal time with a superb long-range free-kick.
The match went to extra time and Daniel Dutch scored the match winner from a corner when he outjumped several Finchley defenders to coolly head the ball into the net to secure a place for Brady in the final.
