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 when-
ever brake lever or pedal action feels soft or
spongy after the brake fluid is changed, or when-
ever a brake line fitting has been loosened for any
The procedure to bleed the front brake line is as follows.
Bleeding the rear brake line is almost the same as for
the front brake.
Remove the reservoir cap, and fill the reservoir with fresh
specified brake fluid to the upper level line in the reservoir.
With the reservoir cap off, slowly pump the brake lever
several times until no air bubbles can be seen rising up
through the fluid from the holes [A] at the bottom of the
Remove the rubber cap from the bleed valve [A] on the
front caliper [B].
Attach a clear plastic hose [C] to the bleed valve, and run
the other end of the hose into a container.
