SERVICE MANUAL
BRAKE SPACING
B
Spread
some strong
thread lock
glue on the
bolt
B
.
In several cases, the distance between the tyre and the frame can be such
as to make need moving the knurled rod
P
more external.
When originally assembling the wheelchair, such possible modification is
already taken into account.
In case of a post-sale modification that results in the rear wheels being
more external (from 0° to 2° or 4° camber; seat width enlargement; a dif-
ferent wheel), the brake may not work efficiently anymore, therefore, you
will have to move the knurled rod. The brake is efficient if the knurled rod
P
is at least 5 mm beyond the tyre’s mid
-line.
In all cases, check the brake efficiency.
Remove the bolt
B
. In order to remove it, put the knurled rod in a vice and heat it with a hot air blower because the bolt is locked with strong
lock thread glue. DO NOT FORCE WHEN UNSCREWING IT, you may damage the bolt’s head irremediably.
Once you have removed the bolt, the knurled rod comes off, too. Replace the bolt
B
according to the spacer
C
(7 or 11 mm) you will add.
Put some strong lock thread glue on the bolt
B
and assemble the spacer
C
and the knurled rod
A
.
Put the knurled rod in a vice and tighten the bolt
B
hard.
It is also possible to move the brake structure
E
from the adjustment rod
F
.
Remove the two nuts
G
and then the two bolts
B
.
Remove the spacers
H
around which the spring is assembles.
Observe how the spring is assembled because you will have to assemble it back later in
the same way (you can always have a look at the other brake that is symmetric).
Insert the spacers
H
(
H
1
= original
;
H
2
= 7
mm longer).
Position the spring and assemble the structure to the adjustment rod.
Start screwing the two bolts
B
all the way down and then the two nuts
G
.
Should the brake movement be hard, slightly loosen the bolts
