Bottas brake failure triggers red flag in final Barcelona practice
Bottas escapes after sudden brake issue
Valtteri Bottas brought the third and final practice session at the Barcelona-Catalunya Grand Prix to a halt after suffering a serious brake problem in his Cadillac.
The Finnish driver went off at Turn 10 with just over 25 minutes remaining in the session, initially making the incident look like an unusual driver error as his car became stranded in the gravel trap. Moments later, however, Bottas made clear over team radio that the problem was far more alarming than a simple off-track excursion.
âI lost my brake pedals. Itâs gone. Like, the pedal is gone,â Bottas told Cadillac. âI got very lucky.â
That message underlined the severity of the moment. At a circuit where rhythm and confidence through braking zones are central to building a qualifying platform, losing the remainder of final practice was a significant disruption for both driver and team.
Cadillac faces another reliability concern
The incident adds to a difficult pattern for the fledgling American-based squad, which has already had to work through various build issues during its debut F1 season. The team also encountered brake problems in Monaco, making this latest failure particularly unwelcome as Cadillac attempts to establish consistency across a race weekend.
Brake reliability has already been a wider talking point in Barcelona, with Ferrari also addressing specification questions elsewhere in the paddock; for more context, read our report on how Charles Leclerc had no issues after Ferrariâs Barcelona brake change. Bottasâs stoppage, though, was a far more immediate concern, ending his track time before he could complete the session.
A setback after encouraging pace
The timing was especially frustrating for Bottas. He has appeared slightly adrift of team-mate Sergio Perez across the season, but it has since been established that irregularities with his car and power unit have left him on the back foot.
In Spain, however, the balance between the two Cadillac drivers had shifted. Bottas had held the edge over Perez so far at the Circuit de Barcelona-Catalunya and had been around a couple of tenths quicker than the Mexican.
That made the failure more costly than a routine practice interruption. Final practice is a crucial window for refining the car before qualifying, and Bottas lost that opportunity just as he had begun to show stronger relative pace. For Cadillac, the red flag was another reminder that performance progress will mean little without the reliability to support it.
