Felipe Nasr is confident that problems with the brakes which compromised his performance at the Belgian Grand Prix has been rectified, as he seeks to return to the points in Italy.
Nasr finished in 11th place at Spa-Francorchamps as an issue with the temperature of his brakes affected the handling of his Sauber C34.
With performance under braking a crucial aspect of lap time at Monza, Nasr is confident that such issues have been fixed.
"I was in the factory last week and brakes was one of the topics we worked on – what we had in Spa was the case of the material: we had 200 degrees difference in the front axle, so the left to right, why I had this pulling feeling in the car," he said.
"I spoke a lot to [brake suppliers] Brembo and they are quite confident that the brakes we are bringing here, they’re quite sure we won’t experience something I had at Spa as my race was completely compromised by lap three or four, a big difference on brake balance and the car was locking wheels all the way in the race."
Nasr added that he was surprised that the problem manifested itself again in Belgium, having been an issue earlier in 2015.
"We saw that a lot in the beginning of the year, not only us but other teams had the same problems," he said.
"I’m surprised it happened again in the middle of the season so what they are doing and checking if they are fine, it’s the best way to minimise something like this."
