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.
Air in the brake lines diminish braking performance
and can cause an accident resulting in injury or
death. If the brake lever or pedal has a soft or
"spongy" feeling mushy when it is applied, there
might be air in the brake lines or the brake may be
defective. Do not operate the vehicle and service
the brake system immediately.
The procedure to bleed the front brake line is as follows.
Bleeding the rear brake line is the same as for the front
Remove the reservoir cap and diaphragm.
Fill the reservoir with fresh brake fluid to the upper level
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
Remove the rubber cap [A] on the caliper.
Attach a clear plastic hose [B] to the bleed valve [C], and
run the other end of the hose into a container.
