CHECKING THE BRAKE FLUID LEVEL
1. Stand the vehicle on a level surface.
TIP
• Place the vehicle on the centerstand.
• Make sure the vehicle is upright.
2. Check:
• Brake fluid level
Below the minimum level mark “a”
→
Add the
recommended brake fluid to the proper level.
WARNING
EWA13540
• 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 master cylinder reser-
voir. Water will significantly lower the boil-
ing point of the brake fluid and could cause
vapor lock.
NOTICE
ECA13540
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
TIP
In order to ensure a correct reading of the brake
fluid level, make sure the top of the brake fluid
reservoir is horizontal.
