FRONT AND REAR BRAKESCHAS
NOTE:
WARNING
CAUTION:
While holding the brake hose, tighten the
union bolt.
Turn the handlebars to the left and right to
make sure the brake hose does not touch oth-
er parts (e.g., wire harness, cables, leads).
Correct if necessary.
4. Fill:
brake fluid reservoir
(with the specified amount of the recom-
mended brake fluid)
Recommended brake fluid
DOT 4
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 fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
5. Bleed:
brake system
Refer to “BLEEDING THE HYDRAULIC
BRAKE SYSTEM” in chapter 3.
