4-3 Brakes (See page 6-17 for details)
1. Brake lever and brake pedal
Check for correct free play in the front brake lever and
rear brake pedal and adjust if necessary. Make sure
the brakes are working properly by checking at low
speed shortly after starting out.
A soft, spongy feeling in the brake lever indicates a
failure in the brake system. Do not operate the
motorcycle until the failure in the brake system is
corrected. Ask a Yamaha dealer or other qualified
mechanic for immediate repairs. A soft, spongy feeling
could indicate a hazardous condition in the brake
system.
NOTE:
If DOT #4 is not available, #3 can be used.
3. Check the disc pads.
Refer to page 6-20
4. Check the brake shoes.
Refer to page 6-20
When a brake service is necessary, consult a Yamaha
dealer or other qualified mechanic.
NOTE:
2. Brake fluid
Check the brake fluid level. Add fluid if necessary.
RECOMMENDED BRAKE FLUID: DOT #4

Inspecting the brake fluid levelInsufficient brake fluid may let air enter the brake system,
possibly causing the brakes to become ineffective. Before
riding, check that the brake fluid is above the lower level
and replenish when necessary. Observe these precautions:

%"



1. When checking the fluid level, make sure the top of the
master cylinder is level by turning the handlebars.
2. Use only the designated quality brake fluid. Otherwise,
the rubber seals may deteriorate, causing leakage and
poor brake performance.
Recommended brake fluid:
DOT #4
NOTE:
If DOT #4 is not available, #3 can be used.

may result in a harmful reaction and lead to poor brake
performance.
4. Be careful that water does not enter the master cylinder
when refilling. Water will significantly lower the boiling
point of the fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted surfaces or plastic
parts. Always clean up spilled fluid immediately.
6. Have a Yamaha dealer check the cause if the brake
fluid level goes down.1. Complete fluid replacement should be done only by
trained service personnel.
2. Have a Yamaha dealer replace the following
components during periodic maintenance or when they
are damaged or leaking.
a. Replace all rubber seals every two years.
b. Replace all hoses every four years. Brake fluid replacement
