3.7 Assembly Group Brakes
3.7.1 Trum brake
The brake force of the drum brakes is set ideally by our technicians.
For safety reasons it is recommended to check the functionality regularly since a readjust-
ment of the brake force or even a replacement of the Bowden cables becomes necessary from
permanent use.
(1+2) The following parts of the drum brake
are of importance in order to adjust the brake
force.
• setscrew (A)
• lock nut (B)
• push-on nipple (C)
• holder (D)
• inner cable (E)
• locking lever (F)
• clamp (G)
• brake shoe (H)
To install the Bowden cable:
• (3) place the push-on nipple (C) with the
setscrew (A) and the lock nut (B) at the
bottom end in the holder (D) ,
• guide the inner cable (E) through the
clamp (G) ,
• place the clamp (G) in the locking lever
(F) and
• push the locking lever (F) slightly for-
ward toward push-on nipple (C) , so that
a slight pull between clamp and push-on
nipple occurs.
• Tighten the clamp (G) .
• Put the wheel back on and check if the
brake shoes (H) already grind against
the brake pad.
• For this, jack up the wheelchair or tilt it to
the side. The wheel must be able to turn
unhindered.
• Should the brake shoes grind (with-
out using the control lever), loosen the
clamp (G) and
• give the locking lever (F) more room.
• After, retighten the clamp (G) .
(3) To set the brake force:
• loosen the lock nut (B) on the drum
brake pad,
• tighten or loosen the inner cable (E) of
the Bowden cable and turn the setscrew
(A) ,
• test the traction on the control lever and
• retighten the lock nut (B) .
Possible impairments of the brake force can
occur from: wrongfully adjusted traction of the
Bowden cables, defected Bowden cable, dirty
brake pads/brake shoes.
