Brake Fluid
Brake Fluid Level Inspection
Refer to the Brake Fluid Level Inspection in the Periodic Maintenance chapter.
Brake Fluid Change
Refer to the Brake Fluid Change in the Periodic Maintenance chapter.
Brake Line Bleeding
The brake fluid has a very low compression coefficient so that almost all the movement of the brake
lever or pedal is transmitted directly to the caliper for braking action. Air, however, is easily
compressed. When air enters the brake lines, brake lever or pedal movement will be partially used in
compressing the air. This will make the lever or pedal feel spongy, and there will be a loss in braking
power.
BE SURE TO BLEED THE AIR FROM THE BRAKE LINE WHENEVER BRAKE LEVER OR
PEDAL ACTION FEELS SOFT OR SPONGY AFTER THE BRAKE FLUID IS CHANGE, OR
WHENEVER A BRAKE LINE FITTING HAS BEEN LOOSENED FOR ANY REASON.
NOTE
THE PROCEDURE YO BLEED THE FRONT BRAKE LINE IS AS FOLLOWS. BLEEDING THE
REAR BRAKE LINE IS THE SAME AS FOR THE FRONT BRAKE.
Remove the reservoir cap [A] and
diaphragm.
Fill the reservoir with fresh brake fluid
to the upper level line in the reservoir.
Slowly pump the brake lever several
times until no air bubbles can be seen rising up
through the fluid from the holes at the bottom of
the reservoir.
Bleed the air completely from the master
cylinder by this operation.
Remove the rubber cap from the
bleed valve [A] on the caliper.
Attach a clear plastic hose to the
bleed valve[B], and run the other end of the hose
into a container.
