Sergio Pérez Demands Improvement After Cadillac Retirements

Sergio Pérez called for a massive internal discussion after Cadillac's brake issues led to both cars retiring in the Austrian Grand Prix on June 29.

What happened?

The team introduced a major new upgrade package at the Red Bull Ring, but the early promise was short-lived as both Pérez and Valtteri Bottas were forced to retire within the first five laps.

Why it matters for Sergio Pérez

Pérez believes it was a misjudgment on Cadillac's part that led the brake temperatures to spike, and he's unhappy with the recurring problems the team has suffered.

The brake problems were unexpected, with Bottas saying there was no warning and everything was under control in practice.

What comes next?

Pérez expects a massive step forward in reliability going to Silverstone, and the team will focus on finding a fix for the brake issues.

Cadillac sources suggest the team was aware it could hit trouble over a longer run, but was caught out by how quickly the brakes overheated.

Pérez had a good start and was looking good out there before the retirement, and he's frustrated with the lack of progress the team has made.

The team will now prioritize finishing the race at Silverstone to learn more about the car and the package.

Bottas had his third DNF in a row, and the team needs to find a solution to the brake problems to move forward.

Pérez is confident that the team can sort out the issues and make a massive step forward in reliability.

The Austrian Grand Prix was a frustrating weekend for the whole team, and Pérez expects a thorough discussion on the team's processes and how they can improve.
