Brake Fluid
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.
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.
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.
We recommend the use of POLARIS DOT 4 high temperature brake
fluid. See page 103 for the part numbers of POLARIS products.
NOTICE: Brake fluid will damage labels, paint and some plastics. Always wipe
up spills immediately.
Replace brake fluid at least every two years.
