(H) Fluid Leaking Into Front Chamber

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

POSSIBLE CAUSES: Reservoir cover and/or diaphragm leaking, damaged Powermaster III Unit.

INSPECT

Reservoir Components:

1. Depressurize the Powermaster III Unit, refer to "Depressurizing the Powermaster III Unit" in Service and Repair.
2. Drain brake fluid in the front reservoir below the divider between the left front and right front chambers.
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". 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.
