3. Fill:
• Brake master cylinder reservoir
(with the specified amount of the recom-
mended brake fluid)
Recommended fluid
DOT 4
EWA13540
WARNING
• 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 perfor-
mance.
• When refilling, be careful that water does
not enter the brake master cylinder reser-
voir. Water will significantly lower the
boiling point of the brake fluid and could
cause vapor lock.
