INSTALLING THE REAR BRAKE MASTER
CYLINDER
1. Install:
• Brake master cylinder “1”
• Rear brake master cylinder holder “2”
TIP
• Make sure that the brake master cylinder as-
sembly touches the end of handlebar bracket
“a”.
• Install the brake master cylinder assembly to
the handlebar “3” at the specified angle “b”.
• First, tighten the upper bolt, then the lower bolt.
2. Install:
• Brake hose gasket “1”
• Rear brake hose “2”
• Brake hose union bolt “3”
WARNING
EWA13531
Proper brake hose routing is essential to in-
sure safe vehicle operation.
NOTICE
ECA14160
When installing the brake hose onto the
brake master cylinder, make sure the brake
pipe touches the projection “a” as shown.
TIP
Turn the handlebar to the left and right to make
sure that the brake hose does not touch other
parts (e.g., wire harness, cables, leads). Correct
if necessary.
3. Fill:
• Brake master cylinder reservoir
(with the specified amount of the specified
brake fluid)
WARNING
EWA13540
• 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 performance.
• When refilling, be careful that water does
not enter the brake master cylinder reser-
voir. Water will significantly lower the boil-
ing point of the brake fluid and could cause
vapor lock.
