6.8 Adjusting the Brake Force – Drum Brake (Fig. 75)
The brake force is adjusted at the adjustment screw (Fig. 75, item A) to achieve optimal braking
effect. The brake force is increased by turning the screw counter-clockwise and decreased by
turning the screw clockwise.
Loosen the counter nut (Fig. 75, item B) and turn the adjustment screw anti-clockwise until a
frictional noise occurs at the wheel. Then tighten the adjustment screw until the frictional noise
disappears. The wheel should run freely.
After nishing the adjustment, fasten the adjustment screw by tightening the counter nut (Fig. 75,
item B).
Ensure that the brake force of both rear wheels is adjusted equally.
Make sure that the drum brake engages with sufcient force only when the manual
brake lever is set to the second ratchet position.
