REAR BRAKE
4-47
WARNING
EWA13090
• Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
• Refill with the same type of brake fluid that
is already in the system. Mixing brake fluids
may result in a harmful chemical reaction,
leading to poor brake performance.
• When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
CAUTION:
ECA13540
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
7. Bleed:
• Brake system
Refer to “BLEEDING THE HYDRAULIC
BRAKE SYSTEM (ABS)” on page 3-23.
8. Check:
• Brake fluid level
Below the minimum level mark “a” → Add the
recommended brake fluid to the proper level.
Refer to “CHECKING THE BRAKE FLUID
LEVEL” on page 3-22.
9. Check:
• Brake pedal operation
Soft or spongy feeling → Bleed the brake sys-
tem.
Refer to “BLEEDING THE HYDRAULIC
BRAKE SYSTEM (ABS)” on page 3-23.
