Bleeding The Hydraulic Brake System - Polaris 2002 Snowmobile Owner's Manual

General Maintenance

Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause a springy or spongy brake
lever action. Bleeding is necessary to remove air from the system.
Brake fluid will damage decals, paint, and some plastics. Wipe
up spills immediately.
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 opening.
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 brake lever a full stroke. Then unscrew bleeder valve 3/4 of a
turn to release air.
5 Close bleeder valve and release brake lever.
6 Repeat steps 4 and 5 until fluid flows from the bleeder valve in a solid
stream free of air bubbles.
Do not overfill the master cylinder. Fluid expansion may cause
brakes to lock, resulting in serious injury or death.
7 After bleeding is complete, refill the reservoir to the proper level. See
Replenishing Brake Fluid on page 126.
8 Reinstall the gasket and cover.
During the bleeding procedure, keep the brake handle in as level a
position as possible. The reservoir must be in this position to
minimize the possibility of air entering the system through the
reservoir vent.
