Brake Adjustments
After opening a bottle of brake fluid, always discard any
unused portion. Never store or use a partial bottle. 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 accident or severe injury.

Front Brakes

The front brakes are hydraulic disc brakes. They're activated by
moving the brake lever toward the handlebar. These brakes are
self-adjusting.
The following checks are recommended to keep the brake system in
good operating condition. Check more often if brakes are used heavily
under normal operation.
1. Always keep brake fluid at an adequate level (see page 42). Under
normal functioning the diaphragm extends into the reservoir as
fluid level drops. If the fluid level is low and the diaphragm is not
extended, a leak is likely and the diaphragm should be replaced.
Always fill the reservoir as needed whenever the cover is loosened
or removed to ensure proper diaphragm operation. Use Polaris
DOT 3 brake fluid (see page 115).
2. Check the brake system for fluid
leaks.
3. Check the brakes for excessive
travel or spongy feel.
4. Check the friction pads for wear,
damage and looseness.
5. Check the security and surface
condition of the disc.
NOTE: Pads should be changed when
worn to 3/64" (.1 cm), or about the
thickness of a U.S. dime.
