A number of Bradbury's players have come in for criticism from a section of the Dean Court support, while the manager's substitution tactics have also come under fire.
But Bradbury, whose side travel to Notts County tomorrow, told the Echo: I won't be scared to makes changes. I think it can shake a few people up when you do that and makes them realise what they've got.
None of the players have got a God-given right to play week in, week out. I've got to make the best decisions for the club and for the team to be successful.
Cherries will be looking to gain revenge for a 3-1 FA Cup second round defeat at Meadow Lane in December, while the Magpies also came back from 3-1 down to take a point from Dean Court in August.
Bradbury added: I feel we owe them one and we really want to win the game.
It's a massive time for us to turn the corner after the run we have had and do well against a team that has beaten us already this season.
As much as Martin Allen will have his troops up for it, I'll have ours up for it too.
