Nico Rosberg says his feeling with the brakes is currently a weakness following the second in-season test of 2014 at the Circuit de Barcelona-Catalunya in Spain.
Rosberg was second quickest behind Lotus’s Pastor Maldonado in Montmelo and says the brakes on the Mercedes W05 Hybrid is currently his main weak point.
“[The] programme was brakes, an area where I’m not feeling too comfortable – just working around doing different solutions, a lot of different findings on there,” Rosberg told journalists, including F1Zone.net.
