Bleeding the Hydraulic Brake System
Air in the hydraulic brake system will cause spongy brake lever action.
Bleed the system before operating the snowmobile.
WARNING! Operating the vehicle with a spongy brake lever can result in loss of
brakes, which could cause an accident and lead to serious injury or death.
Never operate the vehicle with a spongy-feeling brake lever.
During the bleeding procedure, keep the brake handle as level as possi-
ble. The reservoir must be in this position to minimize the possibility of
air entering the system through the reservoir vent.
1. Remove brake master cylinder reservoir cover and gasket.
2. Fill the master cylinder reservoir to between the MIN and MAX
marks or 1/4"-5/16" (.6-.8 cm) below the lip of the reservoir open-
ing. Reinstall the gasket and cover.
3. Slip a rubber tube over the ball of the bleeder valve and direct the
flow of fluid into an approved container.
4. Squeeze the brake lever a full stroke. Then unscrew the bleeder
valve 3/4 of a turn to release air.
