7. Repeat steps 4-6 for the other pad; then secure the
pads with the pin and hairpin clip.
8. Remove the reservoir cover and remove the remain-
ing fluid; then fill the reservoir with fresh fluid.
9. Pump the brake lever to ensure correct positioning of
the brake pads; then release.
10. Fill the reservoir to the proper level with fresh brake

 NOTE: When new brake pads are installed, a "bur-
nishing" process is required. Drive the snowmobile
slowly and compress the brake lever several times
until the pads just start to warm up; then allow them
to cool down. This procedure stabilizes the pad mate-
rial and extends the life of the pads.
