BRAKE FLUID LEVEL INSPECTION/

BRAKE PAD INSPECTION/BRAKE HOSE INSPECTION

WARNING

• Use only the designated brake fluid. Other flu-

ids may deteriorate the rubber seals, causing
leakage and poor brake performance.

• Refill with the same type of fluid. Mixing fluids

may result in a harmful chemical reaction
leading to poor brake performance.

• When refilling, be careful that water does not

enter the brake master cylinder reservoir.
Water will significantly lower the boiling point
of the fluid and may cause vapor lock.

BRAKE PAD INSPECTION

1. Remove:

• Right side cover

Refer to “COVERS” in CHAPTER 3.

2. Apply the brake lever.
3. Inspect:

• Brake pad wear limit 

a 

Wear indicator groove 1 almost disappeared
→ Replace as a set.

Wear limit:

1.5 mm (0.06 in)

BRAKE HOSE INSPECTION

1. Inspect:

• Brake hose

Cracks/damage/wear 

→ Replace.

2. Check:

• Fluid leakage

Apply the brake lever several times.
Fluid leakage 

→ Replace the defective parts.

AIR BLEEDING (HYDRAULIC BRAKE SYSTEM)

AIR BLEEDING (HYDRAULIC BRAKE 
SYSTEM)

WARNING

Bleed the brake system in the following cases:
• The system has been disassembled.
• A brake hose is loosened or removed.
• The brake fluid has been very low.
• Brake operation is faulty.
If the brake system is not properly bled a loss of
braking performance may occur.

1. Remove:

• Right side cover

Refer to “COVERS” in CHAPTER 3.

2. Bleed:

• Brake system

Air bleeding steps:
a. Fill the brake master cylinder reservoir with the

proper brake fluid.

b. Install the diaphragm. Be careful not to spill any

fluid or allow the brake master cylinder reservoir
to overflow.

c. Connect clear plastic hoses 1 tightly to the

brake caliper bleed screws 2.

d. Place the other end of the hoses in a container.
e. Slowly apply the brake lever several times.
f. Pull the lever in, then hold the lever in position.
g. Loosen the bleed screws and allow the brake

lever to travel towards its limit.

h. Tighten the bleed screws when the brake lever

limit has been reached, then release the lever.

i. Repeat steps (e) to (h) until all of the air bubbles

have disappeared from the fluid.

j. Tighten the bleed screws.

NOTE:

If bleeding is difficult, it may be necessary to let the
brake fluid settle for a few hours.
Repeat the bleeding procedure when the tiny bub-
bles in the system have disappeared.

k. Add brake fluid to the proper level.

Refer to “BRAKE FLUID LEVEL INSPECTION”.

WARNING

After bleeding the brake system, check the
brake operation.

Oil level inspection

WARNING

The engine and muffler will be very hot after the
engine has run. Avoid touching a hot engine
and muffler while they are still hot with any part
of your body or clothing during inspection or
repair.

1. Remove:

• Right side cover

Refer to “COVERS” in CHAPTER 3.

2. Place the snowmobile on a level surface.
3. Check:

• Oil level

Checking steps:

• Remove the dipstick 1 and wipe it off with a

clean rag, and then screw it back into the filler
hole.

• Remove the dipstick and check that the oil level

is within the range show at the bottom of the
dipstick. If the oil does not reach the bottom of
the dipstick, add sufficient oil of the recom-
mended type to raise it to the correct level.
