9.7.4 Hydraulic braking type CUNA NC 344-05
Thetrailerbrakingoperatesunderpressure;thehydrauliccircuit
ofthevehicleprovidesaconstantpressuretothetrailerbraking
system.
Byconnectingthebrakingsystemofthetrailertothevehicle,the
trailerisreleasedfromthebrakesandcanmove.
The pressure is varied inproportion to the pressure exertedon
thebrakepedalofthevehicle.
Thetrailerbrakevalve(fig.1502121),locatedonthebackofthe
vehicle, has a lever "A" for the hydraulic braking activation and
deactivation:
– When the lever is in "0" position the hydraulic braking is
activated.
– When the lever is in "1" position the hydraulic braking is
deactivated.

WARNING
With the trailer connected and lever "A" in position "0", the parking brake is enabled on
the trailer.
In case of non-use of the trailer is advisable to move the lever in the "1" position to prevent that the
systems remains under pressure. Keeping the system under pressure entails an unnecessary loss of
engine power, with consequent higher power consumption, and unnecessary heating of the hydraulic oil.
