Lewis Hamilton says Nico Rosberg would have probably had the edge on him in qualifying for the United States Grand Prix even without reliability issues.

Rosberg took pole position by 0.4s in Austin, with Hamilton having been quickest in all three practice sessions. Hamilton revealed after the session that he had endured problems with his brakes but said he was unsure if he would have been able to beat his team-mate even without those issues to contend with.

Asked if braking was difficult for him, Hamilton replied: "Yeah absolutely.

"Obviously Nico did a great job today, I just really struggled with braking. When you looked at the brake temperatures the left brake was always around 100 degrees less than the right front brake and it just kept catching. So no matter what I did, even if I braked earlier and tried to save it, it would still lock.

"So that is perhaps where I was losing a lot of the time but even if that wasn't the case I think Nico was perhaps too quick today."

And Hamilton conceded he has some slight concerns that the problem could carry over in to Sunday's race.

"Potentially, yeah. So I need to try and see, maybe they can scrub it down or something and try to fix it overnight."
