Delivers improved cornering on dry road surfaces
Eliminates the need of snow tyres, tyre chains, etc.
Ensures effective transmission of engine torque to all four wheels, even on slippery road surfaces
Ensures that effective braking can be performed, even on slippery surfaces
Enhances safety by serving two independent lines in a divided line brake circuit
Enhances safety by activating the brakes using vacuum pressure in the event of brake fluid loss
Supplies equal fluid pressure to each line of a divided line brake circuit, thereby preventing the brakes from dragging on one side
Boosts the brake fluid pressure to reduce the force required to depress the brake pedal
