To ensure that the connections have been properly made, the air tank corresponding to an axle can be emptied; the pressure con-
trol on the in-vehicle indicator and the verification, by operating the brake pedal, on the remaining braking section(s), allow such
verification.
Hydraulic circuits must have the normal air bleed operation.
ABS electronic brake control devices
In case of changes to the wheelbase, the original position for ABS modulators must be maintained relative to the axis rear wheels.
The wiring between the sensors on the rear axle and the control unit, as well as between the control unit and the modulators,
must be adjusted using new cables or extension cables with appropriate connectors.
The brake piping upstream of the modulators must also be adequate.
Withdrawing air from the cooling system
In vehicles with a pneumatic brake system it is possible to withdraw a small amount of air from the tank in the auxiliary circuit. This
withdrawal should only occur through a limited return valve, which can avoid the lowering of the pressure below the threshold of
8.5 bar in the operating brake circuit and the auxiliary circuit.
Take the air directly from the 4-way safety valve (exit 24) of the braking system.
