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:
9.2.4 SPARE WHEEL
The spare wheel is located on a bracket on
the side of the trailer. This is of the same
type as the wheel/tyres fitted to the trailer
and is secured in place using two of the
standard wheel bolts. These bolts should be
fitted opposite to each other, e.g. Position
1&2 or 3&4.
9.3 BRAKES & COUPLING
Your trailer is fitted with Knott brakes and
coupling. Supplied within the user manual
pack is a Knott Maintenance & Servicing
information leaflet which covers the
following maintenance procedures:
• Replacing brake assembly complete.
• Replacing brake shoes.
• Brake adjustment.
• Replacing brake cable (Bowden cable).
• Replacing breakaway cable.
• Replacing coupling head & bellow.
• Replacing the coupling damper.
These procedures must be carried out by
competent persons. If you have any doubts
about your ability to complete any of the
procedures we recommend these tasks are
performed by your local distributor.
Brake drum removal and replacement requires
the axle nut to be removed and refitted.
A new axle end nut must be fitted every time
it is removed and refitted. Tighten to a torque
of 350Nm and lock into both sides of
the stub axle groove
as shown adjacent.
