Ross Brawn has insisted his Brawn Formula One motor racing team does not operate a "favouritism" policy following Rubens Barrichello's outburst at the weekend's Spanish Grand Prix.
Barrichello threatened to "hang up his helmet" if he found championship leader Jenson Button was being favoured.
The Brazilian lost Sunday's race in Barcelona to Button after boss Brawn changed Button's strategy.
Brawn says they don't have a one and a two driver, they're both on equal terms and conditions and get the same equipment.
He says he's pleased Barrichello's frustrated because he doesn't want driver's who are prepare to concede but he's fine now they've talked things through.
Team orders are a sensitive subject for Barrichello who left Ferrari in 2005 a year before the end of his contract because he was fed up with not being allowed to race team-mate Michael Schumacher.
Brawn was Ferrari's technical director at the time.
