The water leak Mick Schumacher suffered on his car in Friday's first practice session was caused by "heavy bouncing" around the bumpy street circuit, with Haas chief Guenther Steiner describing the problem as "strange".
The session lasted for just a few minutes for Schumacher, before the young German was told to pull over and stop his car by his race engineer. Water had been pouring out the side of his Haas and onto the track, and he was not able to re-emerge for any practice around the Baku circuit until the next session.
It was not ideal preparation for a young driver under pressure. Schumacher is still yet to score a point in Formula 1 and is one of two drivers yet to do so this season. To make matters worse, he has crashed his car several times – bringing hefty repair bills for a team with a small budget.
