Vehicles not fitted with ABS system have been provided with
the following components to obtain brakeforce distribution:
-
single-circuit load sensing valve;
-
load sensing valve pneumatic actuator.
The load sensing valve controls automatically the braking
torque produced by brakes on the rear axle, according to the
load applied on the rear axle, measured and transferred to the
load sensing valve of the pneumatic actuator.
The load sensing valve used on vehicles with this type of
suspension is set to 0.25 ratio.
