(H)Fluid Leaking Into Front Chamber

Figure 14 - Reservoir Components:

Symptom: Front reservoir chamber becomes overfilled causing leakage past the reservoir cover.

Possible Causes: Reservoir cover and/or diaphragm leaking, damaged Powermaster Ill Unit.


Inspect

1. Depressurize the Powermaster III Unit, refer to "Depressurizing the Powermaster III Unit" in this section.
2. Drain brake fluid in the front reservoir below the divider between the left front and right front chambers (Figure 14).
3. Install the reservoir cover and diaphragm assembly. Turn on the ignition and pump the brakes several times.
4. Again depressurize the Powermaster III Unit, refer to "Depressurizing the Powermaster III Unit" in this section. Remove the reservoir cover and diaphragm. Note the level of fluid in the front reservoir.
5. If the fluid level has risen in either front chamber, replace the Powermaster III Unit.
6. If the fluid level drops or stays the same, replace the reservoir, reservoir cover and diaphragm assembly.
