Front Brake - Polaris Offroad Vehicle Owner's Manual

MAINTENANCE

Front Brake

The front brakes are hydraulic disc type brakes which are activated by the brake
lever being moved toward the handlebar. These brakes are self-adjusting and re-
quire no adjustment.
The following checks are recommended to keep the brake system in good operat-
ing condition. How often they need checking depends upon the type of driving that
has been done.
DKeep fluid level in the master cylinder reservoir between the max and min level
marks at all times. Normal functioning of the diaphragm is to extend into the
reservoir as fluid level drops. If the fluid level is low and the diaphragm is not
extended, a leak is indicated and the diaphragm should be replaced. Always
fill the reservoir as indicated whenever the cover is loosened or removed to
insure proper diaphragm operation. Use Polaris DOT 3 brake fluid (PN
2870990).
WARNING: Once a bottle of brake fluid is opened, use what is necessary and dis-
card the rest. Do not store or use a partial bottle of brake fluid. Brake fluid is hygro-
scopic, meaning it rapidly absorbs moisture from the air. This causes the boiling
temperature of the brake fluid to drop, which can lead to early brake fade and the
possibility of serious injury.
DCheck brake system for fluid
leaks.
DCheck brake system for fluid
