9. Ensure the balance bar (compensation)
is being pulled evenly. This bar (double on
tandem axles) should always be paralleled
with the axle tube when pulled. Adjust M8 lock
and ball nuts, if necessary, to achieve correct
parallel position (Fig. 9)
10. Check the brake rod support bracket (fixed
to the floor) is supporting the brake rod evenly.
The brake rod must always run straight, never
bent or curved under any fittings. On tandem
axles, using the double balance bar, a brake rod
support tube (Part No. 228827) must always
be fitted on the end of the brake rod, passing
through the centre aperture on the abutment.
11. Remove the slack in the brake rod by
adjusting the long ball nut to the rear of the
balance bar, ensuring the overrun lever makes
contact with the end of the towing shaft.
Over-adjustment to the long ball nut (Fig.10)
could induce movement of the inner brake
cable, reducing the effective clearance of
the brake shoes. If the overrun lever will not
make contact, it is possible the two lock nuts,
forward of the spring cylinder, are incorrectly
adjusted. Loosen the nuts and adjust the brake
rod as above (Fig. 8).
12. Adjust the two locking nuts, forward of
the spring cylinder (Fig. 9) (on some chassis
a single Nyloc nut is used) to give 1mm of
clearance on the spring cylinder. This cylinder
(the energy store for the handbrake operation)
must be able to rotate only, not slide on the
brake rod. (See Fig. 9) If the overrun assembly
is fitted with a gas strut handbrake then no
spring cylinder is fitted, ignore this paragraph.
13. Correct adjustment of the linkage is
checked by operating the handbrake lever
so that when the second or third tooth is
engaged, a slight braking force is felt on the
road wheels.
14.Over-adjustment of either the wheel brakes
or linkage will result in difficult reversing
causing the wheels to “lock-up”.
15. When parking, the handbrake lever must
always be engaged into the fully upright
position (90°). This is to compress the spring
within the spring cylinder and thereby create
an energy store, which will automatically
engage the brakes further should the caravan
move.
16. If difficulty is experienced in this operation,
try easing the caravan backwards with one
hand while engaging the handbrake fully
with the other. This manoeuvre should not be
attempted on a rearwards facing slope. In this
case wheel chocks should be used combined
with the handbrake.
17. Finally, if the road wheels have been
removed, re-tighten using a calibrated torque
wrench to 130Nm (on all M12 wheel bolts - in
sequence, i.e. North, South, East, West not
clock or anticlockwise.) DO NOT overtighten
this is just as dangerous as to undertighten, as
this can distort the wheel rims. Avoid the use
of power wrenches.
The torque settings should be re-
checked after 50km/30 miles. Wheel
bolts should never be lubricated.
In order to operate the AL-KO
braking system correctly adequate
traction of caravan wheels is required
when reversing. Therefore surface
conditions that would result in a lack
of traction should be avoided.
Care should be taken when traversing
ramps or other obstacles in order
to prevent damage to the caravan
under gear. When approaching such
obstacles reduce towing speed
appropriately.
