Stewards at F1's Azerbaijan GP found no evidence in telemetry data of Lewis Hamilton either brake-testing or lifting off unexpectedly in his clash with Sebastian Vettel before Sunday's second safety car restart.
Although Vettel is adamant that he was brake-tested on the exit of Turn 15 prior to him making contact with the rear of the Mercedes, analysis of data from Hamilton's car by the FIA showed no proof of that.
The FIA investigation, which took place during the course of the race, threw up no suggestion that Hamilton had braked nor lifted off entirely.
Furthermore, analysis of how Hamilton had behaved in the first safety car restart, and the one after the incident, showed that the British driver had behaved exactly the same at that point of the track as he prepared to get back up to racing speed.
