Strange Sergio Perez Crash Triggers Red Flag After Cadillac Fails
Highlights
- Sergio Perez’s FP3 ended early due to Cadillac rear brake failure.
- Perez experienced engine loss and severe brake issues at Turn 2.
- Session red-flagged, disrupting other drivers’ running time.
- Cadillac faces ongoing challenges with brake temperature management.
- Team must fix issues before qualifying and race day.
Sergio Perez’s FP3 at the Hungarian Grand Prix ends within minutes, his Cadillac MAC-26 stopping with an apparent rear brake failure and triggering a red flag approaching Turn 2.
Perez spends the opening 20 minutes in the garage as mechanics tackle rear-end concerns. On his first push, he reports engine loss and severe braking at the Hamilton corner.
Perez radio: “I lost the engine. I had a massive brake.”
Radio traffic captures, “I lost the engine. I had a massive brake,” before he pulls off with smoke visible from the rear.
The stoppage truncates rivals’ programmes, but the damage is greater for Perez, who loses critical setup mileage ahead of qualifying.
Cadillac’s season-long struggle with brake temperature management persists, and may underpin this failure, though the exact root cause remains unconfirmed.
Hungary’s tight, low-speed layout punishes brakes. Long corner sequences and modest airflow raise temperatures, increasing the risk of rear lock, fade, or fires if cooling is marginal.
Cadillac’s recurring rear brake temperature issues shadow the MAC-26’s development.
The team must now inspect rear hardware, brake-by-wire calibration, and duct architecture, while checking whether a power unit safeguard contributed to the shutdown.
Urgency is high. Major changes remain free before qualifying, but parc ferme from Q1 will limit subsequent alterations, making early fault isolation essential.
Perez, a six-time winner, anchors the new American programme, which is still building consistency after first points in recent weeks.
Losing FP3 laps compromises tire preparation and balance work, increasing sensitivity to wind and track evolution. That raises the risk of a compromised qualifying build-up.
Reliability, not outright speed, is Cadillac’s primary limiter heading into qualifying.
The immediate target is a robust fix and stable brake temperatures for qualifying runs. Longer term, Cadillac must refine cooling and control strategies to protect race execution.
