I wonder why your Airbus requires 2 mins. of gear down with brake de-activated.
Our A300s only need 1 min. and we often have rotate speeds around 170kts.
Just curious.
Also Boeing 727 is the only A/C I've come accross with nose wheel brakes, and then only on short field mod A/C.
A quick google also talks of Convair 880 & 990 having nose wheel brakes. There may be others.
