9.3.1 BRAKE SERVICE
INTERVALS
• Brake adjustment should be checked after
the first 100 miles and subsequently every
1000 miles or 2 months (whichever is the
sooner).
• Brake lining conditions should be checked
every 3000 miles or 6 months (whichever
is the sooner).
This can be carried out as follows without
removing the brake drum:
Remove the two plastic bungs from the
rear of each brake and visually check the
thickness of the lining, replacing the bungs
after checking. If the thickness is less than
1.5mm the linings should be replaced.
• Brake cables. To ensure smooth
operation of the brakes and to reduce the
possibility of premature brake wear, it is
recommended that the brake cables are
replaced every 6000 miles or 12 months
(whichever is the sooner) at the same time
as the brakes are checked.
• Brake linkage. All moving parts should be
greased or oiled monthly.
9.3.2 COUPLING UNIT
SERVICE INTERVALS
• The general condition of the overrun
coupling unit should be checked monthly.
• To minimize wear on your towing ball and
coupling head, clean out the cup in the
coupling head monthly and apply new grease.
Service as follows every 3000 miles or
6 months, whichever is sooner:
34
• Thoroughly examine all moving parts for
wear and correct functioning.
• Grease the drawtube bearings by means of
the grease nipples.
• Clean and grease bearing parts and pivot pins.
• Ensure correct functioning of all pivot pins
and levers and oil monthly.
9.3.3 DRAWTUBE
REACTION TEST
Fully apply the handbrake lever. Push the
coupling head as far back into the housing
as possible. (It will move slowly under steady
pressure.) On release, the coupling head
should slide gradually forward under the
pressure of the gas-filled shock absorber.
If it either fails to return to the forward
position or returns immediately, contact
your authorized distributor for advice.
9.3.4 CHECKING THE
COUPLING HEAD FOR
EXCESSIVE WEAR
With the coupling
disconnected from
the tow ball, observe
the position of
the wear indicator
lug relative to the
"MAX" line. Then,
with the coupling
attached to the tow
ball, re-check the
position of the lug (see diagram). The gap
between the base of the lug and the "MAX"
line should be greater. If it is unchanged,
