Melbourne circuit braking analysis


Melbourne street circuit main characteristics :

Length Km : 5.303 m
Number of laps:

58

Type of brakings: hard
Number of brakings:

8

Downforce Level: High
Tyre Compounds:  

Medium( white stripe) / soft (yellow stripe)

Time spent under braking per lap:

11%

 

 

    Melbourne is a fast track full of demanding braking zones where disc brakes suffer hard pressures and high ware, the surface is quite bumpy particularly in the braking zones  and very slippery at the start of the race weekend as it is used as public roads , the surface of which is full of small debris  . Nevertheless grip gradually increases during weekend  as the track is rubberized m which causes an increase in deceleration and brake stress in terms of wear and temperature .

     Turn 2 is considered the most demanding for the braking system .

    The braking pressure on the 2012 cars is slightly increased compared to previous season . Different tyre compounds in 2012 by Pirelli and evolved 2012 KERS units may well justify the observed difference .
