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
6
other than DOT 4 may result in a
harmful chemical reaction.

Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-

cantly lower the boiling point of
the fluid and may result in vapor

leaking.
Brake seals: every 2 years
