Full ABS with Tandem Control for Freightliner Trucks

Since the introduction of the Freightliner/Wabco individual wheel control ABS in 1987, both Freightliner and Wabco have continued their efforts to develop a simplified and highly cost effective ABS for use on Freightliner vehicles. This ongoing development effort has lead to the 4-channel Freightliner/Wabco Tandem Control ABS. This new Freightliner/Wabco Tandem Control ABS was introduced in 1989 as an alternative to the original Freightliner/Wabco 6-channel individual wheel control ABS for use on typical 3 axle, on highway, tractors and trucks. This paper describes the advantages and the differences between the Freightliner/Wabco 6-channel individual wheel control and the Freightliner/Wabco 4-channel Tandem Control ABS when installed on 3 axle Freightliner vehicles.
