MAINTENANCE OF YOUR CARAVAN
Maintenance work
Check wheel bolts for firm seating - after the
first run under load conditions, likewise after
each wheel change -
Tighten wheel bolts crosswise using a
torque wrench to the tightening torque in
compliance with the table.
Tightening torques of wheel bolts
Check brake play, if necessary readjust -
after the first run under load conditions,
then every 2000-3000 kilometres -
The check is carried out visually on the
stroke (x) of the overrun hitch.
As soon as this reaches more than 50 mm
when the brakes are applied sharply, adjust
the wheel brakes.
Check brake lining wear - every 5000
kilometres -
The brake lining wear is dependent on the
style of driving. Careful driving saves brake
linings and tyres. As soon as a brake lining
has been worn to a thickness of 1 mm, the
brake shoe has to be replaced. Stiff or
stretched brake springs, the coils of which
are no longer closed tightly together, must
also be replaced.
For visual check re-insert the plug (arrow)
out of the brake plate.
ADJUSTING THE WHEEL BRAKES
- every 2000-3000 kilometres of travel -
Jack up the trailer. Release the overrun hitch
and handbrake lever and brake linkage (free
from tension).
Lock the swivel cams of the wheel brake from
the outside by means of auxiliary tool (item A,
pin Ø 4 mm) through the tracing bore.
Tighten the adjusting nuts (item C) on wheel
brakes with a screwdriver (item B) or a wrench
by using the adjusting bolt (item D) until the
wheel locks up.
Centre the brake shoes by actuating the
parking brake several times.
Version 1: Turn the adjusting bolt backwards
until the wheel is running free in direction of
travel (approx. 1 full turn of the adjusting bolt).
