Otto Bock Discovery - Adjusting the Braking Force of the Drum Brake (Option)

3) Firmly tighten the screw connections on the slotted hole of the clamping plate to a torque of 15Nm.
INFORMATION: Adjust the left and right knee lever wheel locks so that they have the same braking
effect.
Adjusting by shifting on the frame (for custom fabrication version with 22"/24" drive wheels)
INFORMATION
Ottobock Custom Fabrication installs the knee lever wheel lock directly on the 22"/24" drive wheels with a clamp
bracket.
1) Loosen the screw connections on the clamp bracket of the knee lever wheel lock (see fig.44, item1).
2) Shift the clamping mechanism on the main frame. When the wheel lock is not engaged, the gap between the
tyre and the wheel lock bolt should be max. 5mm (not illustrated).
3) Firmly tighten the screw connections on the clamp bracket of the knee lever wheel lock (see fig.44, item1).
INFORMATION: Adjust the left and right knee lever wheel locks so that they have the same braking
effect.

6.14.2 Adjusting the braking force of the drum brake (option)
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.45, 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.45, 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.45, item2) until the scraping noise at the rear wheel disappears and
the wheel runs freely.
