 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.

Removing/Disassembling
1. Remove both access panels; then remove the drive
belt (see Drive Belt in this section) and driven clutch.

Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
