A method allows piloting a braking system of a vehicle, the braking system including at least a pair of coupled brake actuators, that includes a pneumatic actuator supplied with a compressed air tank pressurized by a compressor, and an electric actuator. The method includes steps including a) measuring the air pressure of the air tank, b) if the air pressure measured at step a) is inferior to a first threshold value, assessing whether the compressor is able to build up the air pressure of the air tank, c) if the result of the assessment performed at step b) is that the compressor is unable to build up the air pressure of the air tank, operating the braking system in a degraded mode wherein at least the electric actuator is used in case of braking, and d) if the air pressure measured at step a) is inferior to a second threshold value, that is lower than the first threshold value, and if the compressor is unable to build up the air pressure of the air tank, using only the electric actuator in case of new braking actions.
