MAINTENANCE AND LUBRICATION
Brakes
Brake Fluid
Check brake fluid levels for both brake systems before each use of the
vehicle. Always keep brake fluid at an adequate level. Do not overfill.
WARNING
An over-full master cylinder may cause brake drag or brake
lock-up, which could result in serious injury or death. Maintain
brake fluid at the recommended level. Do not overfill.
If the fluid level is low add DOT 3 brake fluid only. See page 112 for
the part numbers of Polaris products.
WARNING
Never store or use a partial bottle of brake fluid. 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. After opening a bottle of brake fluid,
always discard any unused portion.
Under normal operation, the diaphragm extends into the reservoir as
fluid level drops. If the fluid level is low and the diaphragm is not
extended, a leak is likely and the diaphragm should be replaced.
Always fill the reservoir as needed whenever the cover is loosened or
removed to ensure proper diaphragm operation.
