Valtteri Bottas has called on Cadillac to resolve ongoing reliability problems after both he and Sergio Perez retired from the Austrian Grand Prix due to brake fires.
Bottas suffered his third consecutive retirement at the Red Bull Ring in Spielberg. He and teammate Perez exited the race within a few laps when their brakes caught fire.
The Finnish driver said there was no warning during practice sessions. He attributed the failures to a combination of higher ambient temperatures and reduced cooling while running in traffic.
Bottas stressed that the team must finish races to gather data on its upgraded MAC-26 car. He identified completing the British Grand Prix at Silverstone as the immediate priority.
Cadillac introduced new brake cooling parts for the Austrian event, but Bottas noted they proved insufficient.
