Air brakes of trailers (articulated trailers)
control and control of tractor brakes is
done so that braking effect of both vehi-
cles is synchronized.

ulator to 740 ± 20 kPa. When the pres-
sure drops below 550 - 40 kPa by-pass
valves, puts auxiliary devices out of op-
eration (differential lock, engagement of
front drive axle).
