Brake System Inspection
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.
• Keep fluid level in the master cylinder reservoir
1/4/1 (6.4
mm) from the top (between "Min" & "Max" lines on
plastic reservoirs) 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 dia-
phragm should be replaced. Always fill the reservoir to within 1/4" (6.4 mm) of the top (between "Min"
&
"Max" lines on plastic reservoirs) whenever the cover is loosened or removed to insure proper diaphragm
operation. Use Polaris DOT 3 brake fluid (PN 2870990).
• Check brake system for fluid leaks.
• Check brake for excessive travel or spongy feel.
• Check friction pads for wear, damage and looseness.
• Check surface condition of the disc.
• Pads should be changed when worn to 3/64" (.1 cm),
or about the thickness of a dime.
Brake Fluid Level Inspection
The master cylinder is located on the left handlebar. Re-
move the cover and check the brake fluid level often. The
correct fluid level is 1/4" (6.4 mm) from the top "A" (be-
tween "Min" & "Max" lines on plastic reservoirs). If the fluid
level is low add DOT 3 brake fluid PN 2870990 only. Fill
to
1/4" (6.4
mm) from the top (between "Min"
&
"Max" lines
on plastic reservoirs).
When reservoir cover is removed
do not
squeeze brake le-
ver. Fluid may squirt out the compensating port if lever is
pulled.
Wear Line
5/98
Pads should be changed when worn to the
indicator lines (A), as shown. See page 9.1 for
pad wear specifications.
Inspect the brake disc spline and pad wear
surface for excessive wear.
