Delighted manager Phil Parkinson is plotting a second Wembley visit after seeing Bradford make sure of their place in the npower League Two play-offs while all but ending Burton's hopes of automatic promotion.
James Hanson's goal shortly before half-time was enough to for Parkinson's in-form side to triumph 1-0.
Bradford reached the Capital One League Cup final only to crash 5-0 against Swansea of the Barclays Premier League and their hopes of a play-off place looked slight indeed after losing 4-1 at rivals Exeter five weeks ago, but they have earned 17 points in the eight matches since then to make sure of finishing in the top seven.
"It has been a fantastic turnaround since Exeter," said Parkinson. "We were five games unbeaten (after the Wembley defeat) going into the Exeter match, but after we lost that game we had the players in on the Sunday to watch the video and told them what we had got to do to get where we wanted to be.
"We have turned it round through sheer hard work, desire and professionalism and it is not just the 11 players on the field who have got us into this position - it has been a squad achievement.
"The lads have been terrific, it is what this club deserves and now we have got the chance to go Wembley (for the play-off final) twice in one season and when the play-offs start I think the support we will get will be unbelievable for a club at this level.
"The support we had was brilliant and the lads have enjoyed playing in front of our supporters."
The result leaves Burton trailing third-placed Rotherham by three points but with an inferior goal difference, and disappointed manager Gary Rowett said: "Automatic promotion is out of our hands - we will just focus on the play-offs. Reaching the play-offs is a great achievement.
"Gillingham come to us in the last match as champions and hopefully we can celebrate the fact we are in the play-offs. We will be as highly motivated as we always are.
"All credit to Rotherham, they beat Bradford on Tuesday and have won at Plymouth today and if they win their last game that will be a great achievement."
