Cadillac brake issue reported again in Singapore

Motorsport.com reported Valtteri Bottas ran into another brake problem in Singapore, with Cadillac’s season-long MAC-26 overheating issue said to be close to a fix.

Motorsport.com reported that Valtteri Bottas hit another brake problem during the Singapore Grand Prix, with Cadillac’s MAC-26 still affected by an issue that has run through its first Formula 1 season. The outlet said Bottas reported having to lift and coast on lap two, while also describing the problem as almost solved.

The same report said brake overheating on the MAC-26 has already contributed to four retirements this season. Cadillac entered Formula 1 in 2026 and is still chasing its first race win, while Bottas sits 22nd in the drivers’ championship on 0 points. Across his F1 career from 2013 to 2026, Bottas has 256 entries, 10 wins, 19 poles and 67 podiums.

Separately, RaceFans reported Bottas said Cadillac’s factory has better facilities than Mercedes. That comment is distinct from the Singapore brake report, but it adds context around the team’s wider development picture in its debut season.
