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: Soft/hard
Time spent under braking per lap:

11

Melbourne track is 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.

The 2011 cars suffer significantly higher braking pressure compared to last season as they are equipped with the new DRS ( drag reduction system ) and boosted with extra energy from KERS comeback and thus being able to achieve significant higher top speed . Mc Laren even covered both the front and rear brake ducts with wire netting to prevent debris from entering inside the braking components , understanding the significance of steady and non fading out braking performance .

    I hope to post similar analysis for more circuits . I strongly think that Pirelli tyres also play a key role on different 2011-2010 braking performance
