Brake Fluid
Replace brake fluid at least every two
years with Polaris DOT 4 high tem-
perature brake fluid. See page 153 for
the part numbers of Polaris products.
The brake fluid level can be seen
through a plastic sight glass in the
brake reservoir. If the fluid is suffi-
cient, the sight glass will be black. If
the sight glass is any color other than
black, add 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 rap-
idly absorbs moisture from the air. The moisture causes the boiling tempera-
ture 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.
CAUTION
Brake fluid will damage decals, paint and some plastics. Always wipe up
spills immediately.
