Brake Line Air Bleeding - Kubota RTV1140CPX Workshop Manual

RTV1140CPX, WSM

Brake Line Air Bleeding

CAUTION
• Use only DOT-3 brake fluid from a sealed container.
Conforms to motor vehicle safety standard No. 116. Using
other type of ail ruins synthetic resin or rubber installed in
brake system components, and may cause brake failure.
• Avoid contamination of the brake fluid. Thoroughly clean
area around the filler cap before removing. Do not open the
brake fluid reservoir cap unless absolutely necessary.
• Use extreme care when filling the reservoir. If brake fluid is
spilled on power steering hoses, wash off with water
immediately. Brake fluid quickly ruins synthetic resin or
rubber hoses.
NOTE
• The fluid level must be checked several times during the
bleeding operation and replenished as necessary. If the
fluid in the reservoir runs completely out any time during
bleeding, the bleeding operation must be done over again
from the beginning since air will have entered the line.
1. Jack up the front side of machine and remove the front wheels.
2. Connect a clear plastic hose (4) to the bleeder (3), running the
other end of the hose into a container.
3. Pump the brake pedal (5) until it becomes hard, and apply the
brake pedal and hold it.
4. Quickly open and close the bleeder (3) while holding the brake
pedal applied.
5. Release the brake pedal.
6. Check the brake fluid level and fill the reservoir (2) with new
brake fluid.
7. Repeat the previous step for each wheel.
8. Repeat this operation until no more air can be seen coming out
into the plastic hose.
9. When air bleeding is finished, add fluid up to the upper level in
the reservoir.
10. Apply the brake forcefully for a few seconds, and check for fluid
leakage around the fittings.
WARNING
• If the brake pedal has a soft or "spongy feeling" when it is
applied, there might be air in the brake line or the brake may
be defective. Since it is dangerous to operate the vehicle
under such conditions, bleed the air from the brake line
immediately.
