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.
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.
Maintain the brake fluid level between the MIN and MAX marks on
the master cylinder reservoir. Use only Polaris DOT 4 high temperature
brake fluid. See page 99 for the part numbers of Polaris products.
