The London Road outfit were left stunned when the teams met in Dorset after Cherries dished out a 5-1 hammering.
Since that game in August, both clubs have established themselves as League One promotion contenders, with Peterborough gaining the upper hand in recent weeks by forcing their way above Cherries.
Bradbury is expecting the race for a place in the Championship to go down to the wire and admits tonight's live televised meeting (Sky Sports 2, 7.45pm kick-off) is a major match for both clubs.
The Cherries manager said: They will want to put a bit of distance between themselves and us and we want to catch them, so it is a big game and a game we are really looking forward to.
We have got to be composed and have belief in ourselves and each other, as a team, to be able to keep the ball for long periods and try to frustrate them a little bit.
But in the right areas because you do not want to lose the ball at the back when they have three or four very attack-minded players that can score goals.
Bradbury added: It's going to be a tight end to the season and I'm sure it is going to go into the last couple of games. Hopefully, we are in the mix come the end of it.
If the lads apply themselves the way they did on Saturday (against Charlton) for the rest of the season, I'm sure we will be.
Peterborough star George Boyd revealed his side's Dean Court defeat was still fresh in the memory.
He told the Peterborough Evening Telegraph: Defeats like that definitely stick in the mind and we will use that to motivate ourselves tonight. It's a big enough game in its own right anyway. We have to win to put pressure on the teams around us.
But it was a bad day for us. I had a stomach-ache that day and so did several other players and we still don't know what caused it. It was a shock to play so poorly at the time because we had started the season well with two big wins.
Cherries' early season ticket renewal offer closes today. Supporters can get their tickets at this season's prices until 5pm, after which time tickets will not go back on sale until it is confirmed whether the club will be in League One or the Championship next term.
