Pressure Bleeding

Use a diaphragm-type pressure bleeder. The pressure bleeder must have a rubber diaphragm between the air supply and the brake fluid. This prevents air, moisture, oil and other contaminants from entering the brake hydraulic system.

Tools Required
J29567 Brake Bleeder Adapter
J39177 Combination Valve Pressure Bleeding Tool
J28434 Wheel Cylinder Bleeder Wrench

1. Fill the pressure tank at least 2/3 full of brake fluid.
2. Bleed the bleeder each time fluid is added.
3. Charge the bleeder with 140 - 170 kPa (20 - 25 psi) air pressure.





4. Use the J39177 in order to depress and hold the valve stem on the combination valve.





5. Use the J29567 in order to install the bleeder adapter.
6. If the brake pressure modulator valve of the antilock brake system is replaced, or if you suspect that air is trapped inside, bleed the brake pressure modulator valve first. Refer to Brake Pressure Modulator Valve Replacement in Antilock Brake System.
7. Bleed each wheel cylinder or caliper in the following sequence:
7.1. Right rear wheel cylinder.
7.2. Left rear wheel cylinder.
7.3. Right front wheel caliper.
7.4. Left front wheel caliper.
8. Connect the hose from the bleeder to the adapter at the master cylinder.
9. Open the tank valve.
10. Attach the J28434 on a wheel cylinder or caliper bleeder valve.
11. Immerse the opposite end of the hose into a container partially filled with clean brake fluid.

NOTICE: Refer to Fastener Notice in Cautions and Notices.

12. Slowly open the wheel cylinder or caliper bleeder valve at least 3/4 of a turn. Allow the fluid to flow until you see no more air in the fluid.
Tighten
Tighten the wheel cylinder or caliper bleeder valve to 7 Nm (62 inch lbs.).
13. Repeat steps ten through twelve at each wheel until the brake system is bled.
14. Check the brake pedal for sponginess. Check the brake warning lamp for an indication of unbalanced pressure. Repeat the bleeding procedure in order to correct either of these conditions.
15. Remove the J28434.
16. Disconnect the hose from the bleeder adapter.
17. Remove the bleeder adapter.
18. Fill the master cylinder to the proper level.
