Front Brake

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 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.
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 depends
upon the type of driving that has been done.
S Keep fluid level in the master cylinder reservoirs as described on
page 46. 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 whenev-
er the cover is loosened or removed to insure proper diaphragm
operation. Use Polaris DOT 3 brake fluid.
S Check brake system for fluid
leaks.
S Check brake for excessive
travel or spongy feel.
S Check friction pads for wear,
damage and looseness.
S Check security and surface
condition of the disc.
S Pads should be changed when
friction material is worn to
3/64" (.1 cm) (A), or about
the thickness of a dime.
