When a brake cover plate has been disturbed, it is advisable, upon re-assembly, to
centralise the shoes in the brake drum to ensure equal pressure to each. In the case of
the front wheel this is best done before refitting the wheel to the machine, but in the
case of the rear wheel it is best done after refitting.
If brake shoes tend to squeak, when the brake is applied it is generally an indication the
brake shoes are not centralised in the drum.
Centralise brake shoes by:
Ensure the nut securing the cover plate to the wheel spindle and also the fulcrum stud
nut (front only) are slightly slacked off.
Place on the brake expander lever a tubular spanner (to increase the leverage), and, while
maintaining pressure on the tubular spanner (to expand fully the brake shoes), fully
tighten the spindle nut binding the cover plate to the spindle and also the nut on fulcrum
stud.

FRONT BRAKE ADJUSTMENT
Major adjustment of the front brake shoes is made on the brake thrust pins, by fitting
packing washers under the pins, as already described.
Minor adjustment of the front brake shoes is made by altering the position of the brake
cable adjuster on the fork assembly. Unscrew the adjuster to "take up" the front
brake.
The adjuster is locked in position by a nut.
Adjust front brake by:
Place machine on centre stand.
Slacken lock nut on cable adjuster.
Unscrew the cable adjuster till, by rotating the front wheel, it can be felt the brake
shoes are just touching the brake drum.
Then screw back the adjuster two complete turns and tighten the lock nut.
