McLaren MP4-26 - brake duct experiments 23 July 2011
McLaren experimented a lot during practice at the Nurburgring to try and find brake feeling to Lewis Hamiltons liking. Hamilton, who tends to brake very late into corners, started the weekend using discs from Carbon Industries and asymmetric brake ducts, fully open on the left (LF) and partially enclosed (by a drum with rectangular cuts) on the right (RF). During qualifying Hamilton opted to use the open version but with Brembo discs, which team mate Jenson Button had used in the morning practice session. The team also added some corner weight to his car during the Friday and Saturday morning practice sessions in an effort to sort out the instability problem he experienced under heavy braking.
