Late on in the season I don't recall Brawn ever having the kind of dominant 1-2 win at a canter kind of relative pace that they had at the beginning. My impression was that Brawn as a whole dropped back in pace relative to other teams whilst Barrichello overcame his braking issues and overtook Button, although Button also found it difficult under pressure in the latter part of the season. Didn't Brawn pretty much every race bar China in the first half and only win the odd race in the second half?
