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. See page 110 for the part numbers of Polaris
products.
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.
