6.4.4 Adjusting the braking force of the drum brake

INFORMATION
After making adjustments, check that activating the manual brake lever creates a sufficient braking effect.
Note that the drum brake must still be able to produce sufficient braking force even when the manual brake lever
is locked into a ratchet position.
To achieve an optimum braking effect, the braking force is adjusted using the adjustment screw (see fig. 23, item
2).
Increase the braking force: Back off the adjusting screw.
•
Reduce the braking force: Screw in the adjustment screw.
•
1) Loosen the counter nut (see fig. 23, item 1) and back off the adjustment screw until a scraping noise can be
heard when the rear wheel is rotated.
2) Screw in the adjustment screw (see fig. 23, item 2) until the scraping noise at the rear wheel disappears and
the wheel runs freely.
3) Tighten the counter nut (see fig. 23, item 1) until the adjustment screw is fixed.
