Install the master cylinder into the frame, or gently hold the
master cylinder in a vise; remove the
fi
ll cap.
NOTE:
If the master cylinder is already installed into the frame,
remove the brake line (place a large amount of rags under the
front of the master cylinder to collect spillage).
Fill the master cylinder approximately 2/3 full with D.O.T 3 or
D.O.T 4 automotive brake
fl
uid.
NOTE:
To prevent air bubbles, do not pump quickly.
Place your
fi
nger loosely over the master cylinder outlet.
Slowly and
fi
rmly push the cylinder push rod or brake pedal
all the way down and place a
fi
nger over the master cylinder
outlet
fi
tting to seal it.
Let the brake pedal or the master cylinder rod return fully
before removing the
fi
nger from the outlet hole.
Repeat the process until all the
fl
uid coming from the outlet
is bubble-free. Be sure to watch the
fl
uid level in the master
cylinder. If the master cylinder is less than 1/3 full, add brake
fl
uid before further bleeding.
Temporarily plug the outlet
fi
tting and install the master
cylinder cap; during reattachment of the brake line, some air
will enter the system. Now bleed the entire system to remove
the small amount of trapped air in the system.
