Replenishing Brake Fluid
Frequently check the reservoir to be sure it contains the correct amount
of fluid.
Remove the brake master cylinder reservoir cover. Add Polaris brake
fluid (PN 2870990) as required to bring the level up to the top of the
fluid level mark on the inside of the reservoir. The proper fluid level is
1/4-5/16
″
(.6-.8 cm) below the lip of the reservoir opening on most
models.
NOTE:
On some models, 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. Use only Polaris DOT 3 high temperature brake
fluid (PN 2870990). Polaris brake fluid is sold in 12 oz. bottles.
After opening a bottle of brake fluid, discard any unused fluid.
Do not store or use a partial bottle of brake fluid. The fluid is
hygroscopic, meaning it rapidly absorbs moisture from the air.
The boiling temperature of the brake fluid will drop, leading to
early brake fade and the possibility of serious injury.
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.
WARNING
Brake fluid will damage decals, paint, and some
plastics. Wipe up spills immediately.
