FRONT AND REAR BRAKES
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
master cylinder when refilling. Water will
significantly lower the boiling point of the
brake fluid and may result in vapor lock.
3. Air bleed:
• brake system
Refer to "BLEEDING THE HYDRAULIC
BRAKE SYSTEM" in chapter 3.
4. Check:
• brake fluid level
Brake fluid level is below the "MIN" level line
→ Add the recommended brake fluid to the
proper level.
Refer to "CHECKING THE BRAKE FLUID
LEVEL" in chapter 3.
