A braking system includes a power supply supplying electrical power, and first and second brake components at least partially operated by electrical power. A first power supply network electrically connects the power supply and the first brake component, and a second power supply network electrically connects the power supply and the second brake component, the power supply networks being adapted to transmit the electrical power from the power supply to the first and second brake components respectively. An auxiliary power supply link is activatable to electrically connect the first power supply network and the second power supply network only when a failure occurs in one of the first power supply network or the second power supply network, the auxiliary power supply link adapted to transmit the electrical power between the first power supply network and the second power supply network only when the failure occurs.
