There was only 1 relevant practice session (FP2) and Max also had the brake issues at that time. FP3 was in conditions that least suit the Red Bull. The cars are very sensitive. There may be a point in the race tomorrow (towards the end) when the car comes to life on the hard tires as we have seen in the past. Track should be slightly cooler tomorrow and will be more rubbered in.
Max is the only one of the top cars with 2 sets of hard tires, which was the strategy that most used last year.
