Use a screw driver to adjust the star wheel until resis-
tance is felt when turning the brake drum in the direc-
tion of travel. Then, slack back until the brake drum
turns freely.
Check for correct movement of the Bowden cable.
The cable should move 5 to 8 mm. Check for uniform
response when braking. All adjustments must be done
at the wheel brake and not on the brake linkage.
When removing the drum for cleaning the brake
shoes, always ensure that a new flanged nut is used.
Tighten the flange nut to between 280 - 300 Nm.
When re-fitting the wheel, tighten wheel nuts in the
N.S.W.E. sequence and to a torque of 88 Nm.
Note
If the handbrake is not fully applied, there is a risk that the trailer could move backwards. The brake
rod must not be under tension or bowed when the handbrake is disengaged.
AXLE
The axle is fully maintenance free. Check the fixing bolts. If ordering replacement axle, quote all refer -
ence numbers on the oval serial number plate riveted to the axle beam.
En- sure that the draw bar is fully extended. Screw the brake
rod into the pivot head and secure with an M10 nut. Using the M10 ball nut, connect the brake rod to
the Bowden cable via the compensating bracket. Fit and hand tighten the hex securing nut. Tighten
the M10 ball nut on the brake rod until there is no further play on the pivot head against the draw bar
(the draw bar must be fully extended).
The compensating bracket must be square on the brake rod. The current type of Bowden cables are
