MAINTENANCE
Front Brake
The front brakes are hydraulic disc brakes which are activated by
the brake lever being moved toward the handlebar. These brakes
are self-adjusting and require no adjustment.
The following checks are recommended to keep the brake system
in good operating condition. How often they need checking de-
pends upon the type of driving that has been done.
D
Keep fluid level in the master cylinder reservoirs as de-
scribed on page 43. 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 in-
dicated 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).
D Check brake system for
fluid leaks.
D Check brake for excessive
travel or spongy feel.
D Check friction pads for
wear, damage and loose-
ness.
D Check security and surface
condition of the disc.
D Pads should be changed when friction material is worn to
3/64″ (.1 cm) (A), or about the thickness of a dime.
Once a bottle of brake fluid is opened, use what is necessary
and discard the rest. Do not store or use a partial bottle of
brake fluid. Brake fluid is hygroscopic, meaning it rapidly ab-
sorbs moisture from the air. This causes the boiling tempera-
ture of the brake fluid to drop, which can lead to early brake
fade and the possibility of serious injury.
