Air brakes of trailers and semi-trailers
Warning indication of air pressure drop
One-hose and two-hose brakes
One-hose brakes
Air brakes of trailers (semi-trailers) and brakes of the
tractor are designed so that braking effects of both
vehicles are synchronised.
In case of a drop of pressure the transfer valve
disables the secondary consumers (differential lock,
disengagement of the front driving axle).
When driving with a trailer or semi-trailer the foot
brake pedals shall be coupled and secured by a latch!
With braking by one brake pedal the trailer air brakes
are not activated.
C222

control bulb placed on a dashboard.
Tractor with braked trailer or articulated trailer
with pressured drop in air pressure system under 450
kPa must not continue in transport if there is not
increase in air pressure.
