Abstract: A lower aerodynamic screen of a front shield of a motor vehicle includes lateral air guides shaped to channel air passing under the aerodynamic screen towards front disc brakes of the vehicle, wherein each air guide is defined by two substantially vertical lateral walls and by an upper wall linked to upper edges of the lateral walls, the air guide being provided, downstream relative to a direction of flow of the air, with a window defined by rear edges of the lateral walls and the upper wall, from which the air emerges towards the disc brakes, the air guide further including a flap that is movable between a position in which it blocks the window and a position in which it is retracted from the window.
