An aircraft braking circuit having brakes with electromechanical actuators for braking wheels located at the bottom end of at least one undercarriage, wherein the circuit includes a remote unit located at the bottom of the undercarriage close to the actuators and connected to a certain number of said actuators, the remote unit receiving a power supply via a power supply cable going down along the undercarriage, and having as many controlled switches as connected actuators for selectively powering blocking members fitted to the connected actuators, the switches being controlled independently of one another by software parking orders generated by a control unit and passing via a single communications bus going down along the undercarriage to the remote unit.
