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.
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 decals, paint and some plastics. Always wipe
up spills immediately.
Replace brake fluid at least every two
Sight Glass
years with Polaris DOT 4 high tem-
perature brake fluid. See page 141 for
the part numbers of Polaris products.
The brake fluid level can be seen
through the fluid level indicator (a
plastic sight glass) in the master cyl-
inder 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.
