FRONT AND REAR BRAKES

2.Fill:

●

Brake fluid reservoir

CAUTION:

Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
brake fluid immediately.

WARNING

●

Use only the designated quality brake
fluid: other brake fluids may deteriorate
the rubber seals, causing leakage and
poor brake performance.

●

Refill with the same type of brake fluid:
mixing brake fluids may result in a harm-
ful chemical reaction and lead to poor
brake performance.

●

Be careful that water does not enter the
brake master cylinder when refilling.
Water will significantly lower the boiling
point of the brake fluid and may result in
vapor lock.

Recommended brake fluid:

DOT 4

3.Air bleed:

●

Brake system
Refer to “AIR BLEEDING (HYDRAULIC
BRAKE SYSTEM)” in CHAPTER 3.

4.Inspect:

●

Brake fluid level
Brake fluid level is under the “LOWER”
level line

→

Fill up.

Refer to “BRAKE FLUID LEVEL INSPEC-
TION” in CHAPTER 3.
