2006 YAMAHA GRIZZLY 660 brakes

7-79

If your ATV encounters shallow water:
Ride slowly and carefully through slow moving
water, watching for obstacles. Be sure to let
water drain from the ATV and CHECK YOUR
BRAKES FOR PROPER OPERATION when
you come out of the water. Do not continue to
ride your ATV until you have regained ade-
quate braking ability. (See pages 7-63–7-67.)

Checking the brake fluid level
Insufficient brake fluid may let air enter the brake
system, possibly causing the brakes to become in-
effective.
Before riding, check that the brake fluid is above
the minimum level and replenish when necessary.
A low brake fluid level may indicate worn brake
pads and/or brake system leakage. If the brake flu-
id level is low, be sure to check the brake pads for
wear and the brake system for leakage. The rear
brake fluid master cylinder reservoir is located be-
hind panel B. (See page 8-23 for panel removal
and installation procedures.)
Observe these precautions:

When checking the fluid level, make sure the
top of the master cylinder reservoirs are level.


Use only the designated quality brake fluid, oth-
erwise the rubber seals may deteriorate, caus-
ing leakage and poor brake performance.
Recommended brake fluid: DOT 4

Front brake lever free play
The front brake lever should have a free play of
zero mm at the lever end. If not, have a Yamaha
dealer check the brake system.
WARNING
_ Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability
which could lead to an accident.
After servicing:

Make sure the brakes operate smoothly
and that the free play is correct.


Make sure the brakes do not drag.


Make sure the brakes are not spongy. All
air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.

CAUTION:
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high pressure detergent
applications such as those available in coin-
operated car washers.4. Once the majority of the dirt has been hosed
off, wash all surfaces with warm water and
mild, detergent-type soap. An old toothbrush
or bottle brush is handy for hard-to-get-at
places.
5. Rinse the machine off immediately with clean
water and dry all surfaces with a chamois,
clean towel or soft absorbent cloth.
6. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.

7. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may mar the paint or protec-
tive finish.
When finished, start the engine and let it idle
for several minutes.
WARNING
Wet brakes may have reduced stopping ability,
increasing the chance of an accident. Test the
brakes after washing. Apply the brakes several
times at slow speeds to let friction dry out the
linings.
