Abstract
An anti-locking braking control system in which each one of at least two wheels of an axle provides a speed signal for use by a respective control channel of an electronic control unit having 'modified individual wheel control' logic. A pair of control valves are connected in series to regulate the respective wheel brake pressure to obtain a 'select-low wheel control' mode, the 'individual wheel control' logic of the control channels assuring that the series-connected control valves are operated synchronously when reapplication of braking pressure is called for by a respective control channel.
