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.
D
Keep fluid level in the master cylinder reservoirs 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 dia-
phragm is not extended, a leak is indicated and the diaphragm should be
replaced. Always fill the reservoir as indicated whenever the cover is loos-
ened 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.
D
Check brake system for fluid
leaks.
D
Check brake for excessive travel
or spongy feel.
D
Check friction pads for wear, dam-
age and looseness.
D
Check security and surface condi-
tion of the disc.

Pads should be changed when
worn to 3/64
