INSTALLING THE HYDRAULIC UNIT
ASSEMBLY
1. Install:
• Hydraulic unit assembly
ECA21371
Do not remove the rubber plugs or bolts
(M10 1.0) installed in the brake hose union
bolt holes before installing the hydraulic unit
assembly.
Do not allow any foreign materials to enter the
hydraulic unit assembly or the brake hoses
when installing the hydraulic unit assembly.
2. Remove:
• Rubber plugs or bolt (M10 1.0)
3. Install:
• Rear brake hose (hydraulic unit to rear brake
caliper) “1”
• Front brake hose (front brake master cylinder
to hydraulic unit) “2”
• Front brake hose (hydraulic unit to front brake
caliper) “3”
• Rear brake hose (rear brake master cylinder
to hydraulic unit) “4”
•Gasket
• Brake hose union bolt
ECA21121
If the brake hose union bolt does not turn
easily, replace the hydraulic unit assembly,
brake hoses, and related parts as a set.
To route the brake hose, refer to “CABLE
ROUTING” on page 2-13.
4. Connect:
• ABS ECU coupler “1”
Connect the ABS ECU coupler, and then push
the lock lever of the coupler in the direction of the
arrow shown.
5. Fill:
• Brake master cylinder 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.
