Brake Bleeding: Service and Repair

PRECAUTIONS
After finishing repair on a hydraulic line (removing brake pipe), bleed air out of the line using the following precautions and procedures.





1. When bleeding air from lines, keep fluid level in reservoir to Max position.
2. Bleed air in the following order:

- Right front wheel
- Left front wheel
- Right rear wheel
- Left rear wheel





3. During air bleeding, depress brake pedal at least ten times. Keep the pedal depressed for three seconds to fill the master cylinder.
4. To avoid brake fluids from spouting, install the cap of the reserve tank prior to air bleeding.
5. Keep vehicle level.


PROCEDURES
1. Jack up vehicle and support it with safety stands.

CAUTION: Brake fluid reservoir must be 3/4 full during air bleeding.

2. Remove bleeder cap and attach a vinyl hose to bleeder plug.
3. Place other end of vinyl tube in a clear container.
4. Depress brake pedal a few times, and then hold it in depressed position.





5. Have a second person loosen the bleeder screw, drain out fluid, and retighten screw with Special Service Tool (SST) 0K130 430 019 or equivalent.
Tightening torque: 4.3 - 6.5 ft. lbs.(5.9 Nm)

CAUTION:
a) Both people should stay in voice contact with each other.
b) Be sure pedal remains depressed until air bleed screw is tightened.





6. Repeat steps 4 and 5 until no air bubbles are seen.
7. Check for correct brake operation.
8. Verify that there is no fluid leakage. Clean away any spilled fluid with rags.
9. After air bleeding, add brake fluid to reservoir to specified level.

NOTICE: Air bleeding must be done from bleeder screw that is farthest from the master cylinder.
