The apparatus comprises a sensor for generating a vehicle load signal, weighting devices designed to supply a weighted pneumatic pressure as a function of the load signal, and first and second braking control apparatus, both coupled to the weighting devices and comprising respective relay valves which supply at their outlets respective braking pressures, modulated as a function of said weighted pneumatic pressure, to respective braking actuators associated with the wheels of a respective axle or of a respective bogie of the vehicle. The weighting devices comprise an electro-pneumatic drive assembly which is interposed between pneumatic pressure supply means and the drive inlet of the relay valves and an electronic weighting control unit which controls the drive assembly as a function of the load signal, so as to modulate in a predetermined way the pressure at the drive inlet of the relay valves.
