After several reliability issues, Red Bull's chief technical officer Adrian Newey has changed the positioning of the RB6's front brake calipers. Instead of the horizontal position, which lowered the suspension's centre of gravity, he's moved the front calipers back to the more standard vertical position. The previous positioning had led to occasional mechanical failure due to greater movement of the brake pistons, pads and discs. This was a change planned for 2011, but the team took the decision to run with it for qualifying and the race in Japan.
