FEATURES AND CONTROLS
Brake Systems
Master Cylinders/Brake Fluid
The master cylinders are located on the left and right handlebars. Check
fluid levels before each use of the ATV.
The fluid level can be seen
through an indicator window
on the top of the master cylin-
der. This eye will appear dark
when the fluid level is full.
When fluid is low, the eye will
be clear.
NOTE:
When checking the fluid
level, the ATV must be
on level ground with the
handlebars straight.
If the fluid level is low add DOT 4 brake fluid only. Do not overfill. See
page 126 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.
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.
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.
