Burnishing Brake Pads - Arctic Cat ZR 3000 Operator's Manual

4. Carefully move the shield out of the
way; then remove the hairpin clip
securing the brake pads to the cali-
per assembly.
5. Using a pair of pliers, pull the outer
brake pad out of the caliper assembly.

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 1.0 mm (0.04 in.). If
the brake pad thickness is less than
specified, replacement of both pads
is necessary.
7. Using a flat-blade tool, slowly and
carefully 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; then release.

NOTE: If brake lever travel is not
within specification, bleed the brake
system.
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; 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
PC011A
to come to an easy stop; do not over-
apply brakes or "lock up" the track.
3. Repeat
allowing some cooling between
stops.

NOTE: Do not repeat too soon or
too aggressively as to get the brake
disc "red hot."
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.
