7.5.2 Readjusting the knee lever wheel lock

The knee lever wheel lock must be adjusted in case of reduced or uneven braking action – e.g. when the gap
between the wheel lock bolt and the tyre is more than 5 mm.
For 12" rear wheels, the knee lever wheel lock is adjusted using a clamping mechanism with a slotted hole (see
fig. 27).
For the custom fabrication version with 22"/24" drive wheels, the knee lever wheel lock is adjusted on a clamping
mechanism directly on the frame tube (see fig. 28).
1) Loosen the screw connections on the clamping mechanism of the knee lever wheel lock (see fig. 27, item 1;
see fig. 28, item 1).
2) The knee lever wheel lock is continuously adjustable. Set the gap between the tyre and wheel lock bolt to
approx. 5 mm when the wheel lock is disengaged (see fig. 29).
3) Firmly tighten the screw connections on the clamping mechanism of the knee lever wheel lock (see fig. 27,
item 1; see fig. 28, item 1).
INFORMATION: Adjust the left and right knee lever wheel locks so that they have the same braking
effect.
