AL-KO BRAKING SYSTEM ADJUSTMENT
12. Remove the slack in the brake rod by adjusting the long
ball nut, rear of the balance bar, ensuring the overrun
lever makes contact with the end of the towing shaft.
Note! Over adjustment to the long ball nut (Fig 13/Item
2) 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 brake rod as above
(Figs 11, 13a\b).
13. OVER ADJUSTMENT of either the wheel brakes or
linkages, will result in difficult reversing causing the
wheels to 'lock-up'.
14. When parking, the handbrake lever MUST ALWAYS be
engaged into the fully upright position (90°). 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.

15. Finally, if the road wheels have been removed, re-tighten all
M12 wheel bolts using a calibrated Torque Wrench to 110Nm
for Alloy Wheels and 88Nm for steel wheels. The wheel bolts
should be tightened in sequence, ie. North, South, East, West
NOT clock or anti-clockwise (refers to steel wheels only).
Remember to over-tighten is just as dangerous as to under-
tighten, as this can distort the wheel rims. Avoid the use of
power wrenches.
IMPORTANT
The torque settings should be rechecked after 50 km.
Wheel bolts should NEVER be lubricated.
