AIR BLEEDING (HYDRAULIC BRAKE SYSTEM)/
BRAKE HOSE INSPECTION
i. Repeat steps (e) to (h) until all the air bub-
bles have disappeared from the bake fluid.
NOTE:
When bleeding the brake system, make sure
that there is always enough brake fluid in the
brake fluid reservoir, before applying the brake
lever. Ignoring this precaution could allow air
to enter the brake system, lengthening the
bleeding procedure, considerably.
j. Tighten the bleed screw.
NOTE:
If bleeding is difficult, it may be necessary to let
the brake fluid settle for a few hours. Repeat the
bleeding procedure when the tiny bubbles in the
brake system have disappeared.
k. Fill the brake fluid reservoir to the proper
level.
Refer to the “BRAKE FLUID LEVEL
INSPECTION” section.
WARNING
After bleeding the brake system check the
brake operation.
