I think it looks too close to say who is braking later. Cleary Tänak's brake lights are glowing way before he starts proper braking. Maybe it's just very touch sensitive when he is hovering foot over the brake pedal.
But today was published entry list - https://app-cdn.sportity.com/82b343e5-8e65-4914-81b6-e525076a185e/5919ca4f-cb3b-453c-a2f8-c632ccba8483_Entry%20List%20ERC%20ROM%202025%20ver%20C%2025%20June.pdf
BTW, there is more R5 cars that total number of cars on entry list to WRC Rally Estonia...
