Routine maintenance and servicing procedures
8.1
Check brake pad wear at the underside of the caliper
9.1
Rear drum brake wear indicator (A) and index mark (B)
material wear can be checked by looking at
the underside of the caliper (see illustration).
Alternatively, displace the caliper (see Chap-
ter
8)
to check the amount of wear.
2 If the amount of friction material remaining
on the pads is below 1.5 mm, new pads must
be fitted.
A
Warning: Brake pads often wear a t
different rates. I f there i s any
doubt about the condition o f either
o f the pads in a caliper, remove the caliper
and check. Brake failure will result i f the
friction material wears away completely.

Refer to Chapter
8
for details of pad
removal, inspection and replacement.

The rear drum brake is equipped with a
wear indicator (see illustration).
2 As the brake shoes wear and the cable is
adjusted to compensate, the indicator moves
closer to the index mark on the casing. To
check the extent of brake wear, have an
assistant apply the brake firmly; if the
indicator aligns with the index mark, the brake
shoes must be replaced with new ones (see
Chapter 8).

Ensure the throttle twistgrip rotates easily
from fully closed to fully open with the
handlebars turned at various angles. The
twistgrip should return automatically from fully
open to fully closed when released.
2 If the throttle sticks, this is probably due to
a cable fault. Remove the cable and lubricate
it (see Chapter 4).
3 With the throttle operating smoothly, check
for a small amount of freeplay in the cable,
measured in terms of the amount of twistgrip
rotation before the throttle opens, and
compare the amount to the Specifications at
the
beginning
of
this
Chapter
(see
illustration).

If there is insufficient or excessive freeplay,
loosen the locknut on the cable adjuster, then
turn the adjuster until the specified amount of
freeplay is evident, then retighten the locknut
(see illustration). If the adjuster has reached
its limit of adjustment, replace the cable with a
new one (see Chapter 4).
5 Start the engine and check the idle speed. If
the idle speed is too high, this could be due to
incorrect adjustment of the cable. Loosen the
locknut and turn the adjuster in
-
if the idle
speed falls as you do, there is insufficient
freeplay in the cable. Reset the adjuster (see
Step 4). Note: The idle speed should not
change as the handlebars are turned. I f i t
does, the throttle cable is routed incorrectly.
Rectify the problem before riding the scooter
(see Chapter 4).
