Rapid-emergency brake
The rapid-emergency brake is combined with the hand brake. If the
caravan is involuntarily disconnected from the base vehicle, the hand
brake will be tightened or moved beyond the dead centre position by
the traction force of the rapid-emergency brake
k
. The hand brake
will be employed and the caravan will do an emergency brake. This
prevents the caravan from continuing to roll without braking after it
has been disconnected.

Before driving, the rapid-emergency brake must be
fastened to the base vehicle.
3.7 Overrunning equipment and wheel brakes
1. If it is possible to push the towbar more than halfway (approx. 5
mm) in when the locking brake has been activated, the braking
system must be regulated immediately by an experienced shop.
2. To check the reaction point:
Activate the locking brake and push the caravan backwards until
the hand brake lever is completely tilted. Then push the safety
clutch into the overrunning equipment. The towbar must extend
into the neutral position by itself by means of the gas cushion in
the hydraulic shock absorber. Should this procedure take longer
than 30 seconds, the overrunning equipment must be checked
by an experienced shop.
The overrunning brake facility consists of the overrun coupling, a
transmission and the wheel brakes. Should the caravan bump into
the base vehicle, the overrunning brake facility ensures that it will
automatically brake. In other words, the overrunning brake facility
functions independently from the base vehicle's brake system. The
brake force that is generated depends mainly on how intensely the
base vehicle brakes and how heavily the caravan has been loaded. A
shock absorber integrated in the overrun coupling and with a dened
response threshold ensures, on the one hand, a smooth overrun
while, on the other hand, preventing the caravan from braking if you
only take your foot o the gas or change gears in the base vehicle.
Checking the overrunning equipment
We recommend that you always check this is functio-
ning correctly before using the caravan.
