Antilock Brake System (ABS) With Traction Control System (TCS)

The TCS modulator/motor pack assembly controls drive wheel slip during acceleration by modulating brake pressure to the drive wheels to prevent slip. The basic TCS modulator configuration consists of gear assemblies, ball screws, nuts, pistons, and hydraulic poppet valves. The motor pack consists of two motors and two drive gears.
