A vehicle antiskid brake control system in which a skid control signal for modulating brake pressure at any one of the wheels is obtained when a disparity results from the comparison of a wheel velocity signal with a reference velocity signal formed by one or more of the wheel velocity signals so as to approximate the vehicle speed. The system includes an additional wheel velocity signal generator network in parallel with the conventional signal generator network at one or more wheels together with low and high signal selectors arranged so that a false wheel velocity signal arising from one of the signal generator networks due to a malfunction is rejected, thereby assuring that only the accurate wheel velocity signal from the other signal generator network is capable of influencing formation of the reference signal.
