MAINTENANCE
Brake Fluid
Check brake fluid levels for both brake systems before each ride.
Always maintain brake fluid at the recommended level. Do not overfill.
If the fluid level is low add DOT 4 brake fluid only. See page 119 for the
part numbers of Polaris products.
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. To
ensure proper diaphragm operation, always fill the reservoir as needed
whenever the cover is loosened or removed. 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 recom-
mended level. Do not overfill.
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.
