He said the Fast Six session was “really tricky” due to the problem, but he beat his Rahal Letterman Lanigan Racing team-mate Christian Lundgaard by just over a tenth of a second to take his fourth career pole and his first since Detroit 2017.
“In Q1, I think we were still P2 or 3, but I was not pleased at all with the car,” he said. “Even in Q2, when we were P1, it was just a terrible lap.
“That's always a good sign. It's nice to be able to feel that way. It's been a long, long time since I felt very in control, could make it happen when we needed to, put it together.
“Q3, it was really tricky, frankly. My brake pedal was really, really long through all of qualifying, which it was this morning, too. We bled them. Thought it was going to be better. It wasn't.
“I locked a few times in Q3. Kind of released the pedal and hoped it stuck, and it worked out.”
When asked to explain the problem further, he replied: “The one thing I will say with these brakes, if you rebuild the callipers and stuff back at the shop, for some reason it's exceptionally hard to get them functioning correctly afterwards. It takes a lot of time.”
