Brakes

Hydraulic Brake Inspection

Inspect the brake lever reserve before each use of the snowmobile. See Brake Lever Travel.
Brake pads must be replaced when the brake pad material becomes thinner than the backing plate (approximately 1/16 inch or 1.5 mm). A kit is available for replacing brake pads. See your dealer.
WARNING
Brake failure during operation can result in serious injury or death. Properly functioning brakes are vital to your safety. Be sure the brake pads do not drag on the disc and that brake lever travel is not excessive. Always replace brake pads when the brake pad material becomes thinner than the backing plate (approximately 1/16 inch or 1.5 mm).

Brake Components

  • Brake Caliper
  • Brake Disc
  • Brake Pad Material (replace when thickness is less than 1/16 inch or 1.5 mm)
  • Anti-rattle springs (come with brake pad kit)

Excessive Lever Travel

Hydraulic brakes are self-adjusting, but if excessive brake pad clearance develops, bring the snowmobile to an authorized POLARIS dealer for inspection and adjustment.

Brake Fluid

The brake fluid level can be seen through a plastic sight glass in the brake reservoir. If the fluid is sufficient, the sight glass will be black. If the sight glass is any color other than black, add brake fluid.
Replace brake fluid at least every two years with POLARIS DOT 4 high temperature brake fluid, or an equivalent product.
WARNING
After opening a bottle of brake fluid, always discard any unused portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade and the possibility of accident or serious injury.
WARNING
Keep the master cylinder cover free of dirt and debris. The vent slits allow for diaphragm movement, and if they become plugged, movement of brake fluid below the diaphragm may be restricted, altering brake function.
NOTICE
Brake fluid will damage labels, paint and some plastics. Always wipe up spills immediately.

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.
caution
Hot exhaust system parts can cause burns. Allow adequate time for the exhaust system to cool. Never perform this procedure with the engine running.
During the bleeding procedure, keep the brake handle as level as possible. The reservoir must be in this position to minimize the possibility of air entering the system through the reservoir vent.
  1. Remove the 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 inch (.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 the brake lever a full stroke. Then unscrew the bleeder valve 3/4 of a turn to release air.
  5. Close the bleeder valve and release the brake lever.
  6. Repeat steps 4–5 until fluid flows from the bleeder valve in a solid stream free of air bubbles.
    WARNING

    Overfilling the master cylinder leaves no room for fluid expansion and may cause the brakes to lock, resulting in serious injury or death. Always add brake fluid to the fill line as recommended.

  7. After bleeding is complete, refill the reservoir to the proper level. See Brake Fluid.
  8. Reinstall the gasket and cover.
