1. A braking system for a vehicle at least partially propelled by an electric traction motor electrically connected to an electric power system, the braking system comprising:
an electric machine configured to be electrically connected to the electric power system, the electric machine comprising a first output shaft and a second output shaft,
an air blower controllably connected to the first output shaft by a clutch, the clutch being controllable between an open position in which no power is transmitted from the electric machine to the air blower, and a closed position in which power is transmitted from the electric machine to the air blower, and
a fluid pump operatively connected to the electric machine via the second output shaft, wherein the fluid pump is arranged in upstream fluid communication with a fluidly operated member and in downstream fluid communication with a fluid tank,
wherein the fluid tank is arranged in downstream fluid communication with the fluidly operated member.
