The League Cup finalists, 3-2 down from Thursday's game at Valley Parade, recorded their first-ever win at the Pirelli Stadium courtesy of Nahki Wells' double either side of James Hanson's goal, running out 3-1 winners.
Jacques Maghoma levelled up the tie from the penalty spot but Burton could not get themselves back on terms again after Wells had struck his 25th goal of the season - and his fifth against Albion this campaign.
It was from a Burton attack that the visitors opened the scoring after 27 minutes. Jon McLaughlin made a routine save from Damien McCrory's free-kick and quickly distributed the ball to James Meredith, who knocked it long.
Albion centre-half Marcus Holness tried to head back to his goalkeeper but did not get enough on it and Wells nipped in to poke past the onrushing Stuart Tomlinson from inside the box.
The opening dozen minutes of the second half saw the tie swing one way and then the next.
Hanson put Bradford ahead on aggregate for the first time after 50 minutes. Wells' persistence enabled him to poke the ball into the path of Hanson and the big striker drilled a right-foot shot into the bottom left-hand corner of the net from 20 yards out.
However, five minutes later the hosts levelled up the tie. Maghoma turned Garry Thompson out on the left touchline and powered towards the penalty area with the Bantams midfielder in tow. Thompson made a last-ditch challenge which referee Graham Scott adjudged to be inside the box and Maghoma got up to score from the spot.
But Burton were level for only two minutes. McLaughlin's long punt forward was headed down by Hanson and Wells spun his marker to flick a left-foot shot past Tomlinson from six yards out.
Bradford had to survive some late Burton pressure but they did and they will return to Wembley for the final on May 18 where they will play either Cheltenham or Northampton, who play the second leg of their semi-final on Sunday evening.
