3. Fill:

mended brake fluid)

WARNING
S Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
S 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.
S When refilling, be careful that water does
not enter the reservoir. Water will signifi-
cantly lower the boiling point of the brake
fluid and could cause vapor lock.

and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
