Master Cylinder/Brake Fluid
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.
Check the brake fluid in the master cylinder before each ride.
-
Position the ATV on a level surface.
-
Position the handlebars so the master cylinder 1 is level.
-
View the brake fluid level through the indicator window 2 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.
-
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.
-
Reinstall the cover. Torque screws to 7 in-lbs (1 N·m).
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.
