Adjusting The Front Disc Brake - Yamaha FJR1300A(D) Service Manual

TIP
• Be careful not to spill any clutch fluid or allow
the clutch master cylinder reservoir to over-
flow.
• When bleeding the hydraulic clutch system,
make sure there is always enough clutch fluid
before applying the clutch lever. Ignoring this
precaution could allow air to enter the hydraulic
clutch system, considerably lengthening the
bleeding procedure.
• If bleeding is difficult, it may be necessary to let
the clutch fluid settle for a few hours. Repeat
the bleeding procedure when the tiny bubbles
in the hose have disappeared.
1. Bleed:
• Hydraulic clutch system

clutch lever.

bles have disappeared from the clutch fluid in
the plastic hose.
