Brakes

WARNING
Operating the vehicle with a spongy brake pedal can result in loss of braking, which could cause an accident resulting in severe injury or death. Never operate the vehicle with a spongy-feeling brake pedal.
The front and rear brakes are hydraulic disc type brakes activated by the brake pedal.
caution
Brake discs can become extremely hot after operation. Allow the discs to cool before performing maintenance to prevent risk of burns.
Always check brake pedal travel and the brake fluid reservoir level before each use of the vehicle. When applied, the brake pedal should feel firm. Any sponginess would indicate a possible fluid leak or low brake fluid level, which must be corrected before riding. See the Brake Fluid section for further details.
If you discover any irregularities in brake system operation, including excessive pedal travel, contact your dealer for proper diagnosis and repairs.

Brake Fluid

Inspect the level of the brake fluid before each operation. If the fluid level is low add DOT 4 brake fluid only. See the POLARIS Products chapter for the part numbers.
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 severe injury.

Change the brake fluid every two years and any time the fluid becomes contaminated, the fluid level is below the minimum, or if the type and brand of the fluid in the reservoir are unknown. Access the brake fluid reservoir through the left front wheel well.

  1. Position the vehicle on a level surface.
  2. Place the transmission in PARK.
  3. View the brake fluid level in the reservoir. The level should be between the maximum and minimum level lines.
  4. If the fluid level is lower than the lower level line, add brake fluid to the upper line.
  5. Apply the brake forcefully for a few seconds and check for fluid leakage around the fittings.

Brake Inspection

WARNING
Do not apply WD-40 or any petroleum product to brake discs. These types of products are flammable and may also reduce the friction between the brake pad and caliper.
Image
  1. Check the brake system for fluid leaks.
  2. Check the brake pedal for excessive travel or a spongy feel.
  3. Check the friction pads for wear, damage and looseness.
  4. Check brake discs for signs of cracks, excessive corrosion, warping or other damage. Clean any grease using an approved brake cleaner or alcohol.
  5. Inspect the brake disc spline and pad wear surface for excessive wear. Change pads when worn to 0.030'' (0.762 mm) .
