INSTALLING THE REAR BRAKE MASTER
CYLINDER
1. Install:
• Brake hose gaskets
• Brake hose
• Brake fluid reservoir hose
• Brake hose union bolt
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.
2. Fill:
• Brake fluid reservoir
(with the specified amount of the specified
brake fluid)
WARNING
EWA13090
• 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 fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
NOTICE
ECA13540
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
3. Bleed:
• Brake system
Refer to “BLEEDING THE HYDRAULIC
BRAKE SYSTEM (ABS)” on page 3-16.

specified brake fluid to the proper level.
Refer to “CHECKING THE BRAKE FLUID
