2007 YAMAHA RHINO 660 brake

7-21
If you start to lose traction or momentum when
climbing, and you decide you will be unable to con-
tinue, use the brakes to come to a stop. Do not at-
tempt to turn the vehicle around. With your foot on
the brake, look behind you and plan your descent.
Shift the drive select lever in reverse so you can
use the engine brake if necessary to slow your de-
scent. Release the brake and begin to coast down
the hill. Use engine braking as much as possible,
gently applying the brakes when necessary.
GOING DOWNHILL
Check the terrain carefully before going down a
hill. When possible, choose a path that lets you
drive your vehicle straight downhill. Avoid sharp
angles that could allow the vehicle to pitch or roll
over. Carefully choose your path and drive no fast-
er than you will be able to react to obstacles that
may appear.

WARNING
Going down a hill improperly could cause loss
of control or cause the vehicle to overturn.

Always check the terrain carefully before
you start down any hill.


Never go down a hill at high speed.


Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.
Before starting down hill, make sure the vehicle is
in low-range 4WD. On most slopes, this will let you
use engine braking to help you go downhill slowly.
Go as slowly as possible. If you are starting to go
too fast, apply the brakes gently. Avoid sudden ap-
plication of the brakes, which could cause the ve-
hicle to start sliding.
If you are sliding or skidding, try to steer in the di-
rection the vehicle is sliding to help you regain con-
trol.

CROSSING THROUGH SHALLOW WATER
If you must cross shallow, slow moving water up to
the depth of the vehicle’s floorboards, choose your
path carefully to avoid sharp drop-offs, large rocks,
or slippery surfaces that could cause the vehicle to
overturn. Never operate through water deeper
than 33 cm (13 in) or fast flowing water.
Wet brakes may have reduced effectiveness. After
leaving the water, test your brakes. If necessary,
apply the brakes several times to let friction dry out
the linings.
WARNING
Never operate this vehicle in fast-flowing water
or in water deeper than 33 cm (13 in). This
could result in a loss of control and an acci-
dent, including a overturn, which could in-
crease the risk of drowning. Remember that
wet brakes may have reduced stopping ability.
Test your brakes after leaving water. If neces-
sary, apply them several times to let friction
dry out the linings.

ENCOUNTERING OBSTACLES ON THE TRAIL
If you cannot go around an obstacle such as a fall-
en tree trunk or a ditch, stop the vehicle where it is
safe to do so. Set the parking brake and get out to
inspect the area thoroughly. Look from both your
approach side and the exit side. If you believe you
can continue safely, decide the path that will allow
you to get over the obstacle at as close to a right
angle as possible to minimize vehicle tipping. Go
only fast enough to maintain your momentum but
still give yourself plenty of time to react to changes
in conditions. If there is any question about your
ability to maneuver safely over the obstacle, you
should turn around, if the ground is flat and you
have the room, or back up until you find a less dif-
ficult path.
WARNING
Before operating in a new area, check for ob-
stacles. Use extreme caution when operating
over large obstacles, such as large rocks or
fallen trees.

Front brake pad check
Each brake pad is provided with wear indicator
grooves, which allow you to check the brake pad
wear without having to disassemble the brake. To
check the brake pad wear, check the wear indica-
tor grooves. If a brake pad has worn to the point
that the wear indicator grooves have almost disap-
peared, have a Yamaha dealer replace the brake
pads as a set.NOTE:_ The wheels need to be removed to check the
brake pads. (See pages 8-107–8-109 for wheel re-
moval and installation procedures.) _
