WARNING
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
 Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing
performance.
 Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
 Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
 Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
 Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water

brake system for leakage. If the brake
