Brake duct development at Renault
With Circuit de Gilles Villeneuve being particularly hard on the brakes, all teams have modified their braking systems to cope with the additional demand. On a full lap, the cars are for 16% of the time under braking, more than any other track on the calendar.
Renault for instance clearly increased the brake duct aperture, catching more air to provide more cooling to the brake discs and pads (notice the difference with the Turkish configuration in the inset). Renault also ran a new front wing, removing the stacked elements of the wing. The rear wing was also modified, retaining the unique W-shape, but extending its curves and reducing the frontal surface of the wing.
I'm new here, and have just gotten back from the Canadian Grand Prix wondering what the heck happened to the Red Bulls. Aside from staying out with heavily grained tyres, I think Vettel was having overheating issues with his brakes. This is very odd since the brake ducts on the RB06 look gargantuan compared to the R30.

The R30's front wing end plates look like they divert air flow away from the brake duct as well. Plus, the duct's vertical composition on first glance would scream "overheating" to me especially on a track like Gilles Villeneuve. Was the R30 having brake issues in Canada as well?
