FEATURES AND CONTROLS
Master Cylinder/Brake Fluid
WARNING
An over-full master cylinder may cause brake drag or brake lock-up, which could
result in an accident. 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 brake failure, which could result in an accident. After
opening a bottle of brake fluid, always discard any unused portion.
Check the brake fluid in the
master cylinder before each ride.
1. Position the ATV on a level
surface.
2. Position the handlebars so
the master cylinder is level.
3. View the brake fluid level
through the indicator win-
dow on the top of the master
cylinder. The eye will
appear dark when the fluid
level is full. When fluid is
low, the eye will be clear.
4. If the fluid level is low, remove the cover screws and add fluid to the
fill line. Do not overfill. Use DOT 4 brake fluid only.
5. Reinstall the cover. Torque screws to 7 in. lbs. (.8 Nm).
