Overrunning Equipment And Wheel Brakes - Hobby 350 TB De Luxe Operation Manual

3.6 Overrunning equipment
and wheel brakes
The overrunning brake facility consists of the
overrun coupling, a transmission and the wheel
brakes. Should the camper bump into the base
vehicle, the overrunning brake facility ensures
that it will automatically brake. In other words,
the overrunning brake facility functions indepen-
dently 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 camper has been loaded. A shock
absorber integrated in the overrun coupling and
with a defined response threshold ensures, on
the one hand, a smooth overrun while, on the
other hand, preventing the camper from braking
if you only take your foot off the gas or change
gears in the base vehicle.
Checking the overrunning
equipment
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 expe-
rienced shop.
2. To check the reaction point, activate the
locking brake and push the camper back-
wards until the hand brake lever is completely
tilted. Then push the safety clutch into the
overrunning equipment. The towbar must ex-
tend into the neutral position by itself by me-
ans 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.
Wheel brakes
The wheel brakes that have been used are drum
brakes that do not automatically adjust. They
have an automatic reverse that is sensitive to the
course you drive. The linings of the wheel brakes
are wear and tear parts; therefore, they must be
checked every 5,000 km or at least once every
year. One sure sign of strong brake lining wear
is described in the aforementioned check for the
overrunning equipment: if the safety clutch can
be pushed in more than approx. 45 mm.
