NOTE: Changing one pad at a time
will prevent one piston from pushing
out the other piston from the caliper.
6. Measure the thickness of the brake
pad. The brake pad thickness must
be greater than 5.0 mm (0.20 in.). If
the brake pad thickness is less than
specified, replacement of both pads
is necessary.

7. Using a flat-blade tool, slowly and care-
fully push the piston into the caliper.
8. Position the outer brake pad into the
caliper; then install the hair-pin clip
into the caliper assembly.
9. Repeat steps 5-8 for the inner pad; then
secure the pad with the hairpin clip.
10. Remove the reservoir cover and
remove the remaining fluid; then fill
the reservoir with fresh fluid and
install the cover.
11. Pump the brake lever to ensure cor-
rect positioning of the brake pads
and proper brake lever travel (see
Checking Brake Lever Travel sub-
section); then release.
NOTE: If brake lever travel is not
within specification, bleed the brake
system (see Bleeding Brake System
sub-section).
12. Remove the reservoir cover and fill
the reservoir (if necessary) to the
proper level with fresh brake fluid;
then install the cover.
13. Secure the brake shield, the driven
pulley (tightened to 20 ft-lb), and the
rear belt guard; then close and
secure the left-side access panel.
NOTE: When new brake pads are
installed, a “burnishing” process is
required (see Burnishing Brake Pads
sub-section).
Burnishing Brake Pads
After changing brake pads, the new brake
pads must be burnished to achieve full
braking effectiveness. Braking distance
will be extended until brake pads are
properly burnished.
To properly burnish the brakes, use fol-
lowing procedure:
1. Choose an area sufficiently large to
safely accelerate to 30-40 mph and
to brake to a stop.
NOTE: This procedure can also be
accomplished using a shielded jack
stand.
2. Accelerate to 30-40 mph; then com-
press brake lever to decelerate to a
stop.
NOTE: Lightly apply the brake
lever to come to an easy stop; do not
over-apply brakes or “lock up” the
track.
3. Repeat procedure 10-15 times
allowing some cooling between
stops.
NOTE: Do not repeat too soon or
too aggressively as to get the brake
disc “red hot.”
NOTE: This procedure stabilizes
the pad material and extends the life
of the pads.
Drive Belt
The drive belt transfers power from the
drive clutch to the driven pulley. If the
belt is worn, cracked, or stretched, maxi-
mum power will not be transmitted and
the belt could also fail and therefore must
be replaced. Periodic checks (at least
once a month under normal usage) of two
drive belt specifications are essential.
! WARNING
Do not attempt sudden stops or put
yourself into a situation where a sud-
den stop will be required until the
brake pads are properly burnished.
