HYDRAULIC BRAKE
PEDAL (COMBI) BRAKE FLUID FILLING
Add fluid and bleed any air from the pedal brake line in
the sequence as follow:
1. Front brake caliper center bleed valve
2. Rear brake caliper bleed valve
Fill the reservoir with DOT 4 brake fluid from a sealed
container.
Operate the brake pedal several times to bleed any air
from the master cylinder.
Connect a commercially available brake bleeder [1] to
the front brake caliper center bleed valve.
If air is entering the bleeder from around the bleed valve
threads, seal the threads with teflon tape.
1. Operate the brake bleeder and loosen the front
brake caliper center bleed valve. Add fluid when the
fluid level in the master cylinder is low to prevent
drawing air into the system.
2. Repeat the above procedures until a sufficient
amount of fluid flows out of the front brake caliper
center bleed valve.
It is not problem if the fluid flowing out from the center
bleed valve contains air bubbles because the lines will
be bled later (page 19-15).
Connect a commercially available brake bleeder [1] to
the rear brake caliper bleed valve.
Repeat above step 1. and 2. for rear brake caliper bleed
valve.
Bleed the hydraulic system (page 19-15).
If a brake bleeder is not available, use the following
procedure:
Connect a bleed hose [1] to the front brake caliper
center bleed valve [2].
1. Pump the brake pedal several (5 – 10) times quickly,
then push the brake pedal all the way down, loosen
the front brake caliper center bleed valve 1/4 of turn.
Wait several seconds and close the bleed valve.
Release the brake pedal slowly and wait several
seconds after it reaches the end of its travel.
2. Repeat the above procedures until a sufficient
amount of the fluid flows out from the front brake
caliper center bleed valve.
It is not a problem if the fluid flowing out from the front
brake caliper center bleed valve contains air bubbles
because the lines will be bled later (page 19-15).
