^ Disconnect harness connectors from ABS actuator relay box before checking.

TESTING

Brake Fluid Pressure Gauge:

1. Connect brake fluid pressure gauge to air bleeders of front and rear brakes on either LH and RH side.





2. Bleed air from the brake fluid pressure gauge.

Brake Pedal Fluid Pressure:

Brake Fluid Pressure Chart:

CAUTION:
^ Depress pedal slowly when raising front brake pressure.
^ Check rear brake pressure 2 seconds after front brake pressure reaches specified value.

3. If output pressure is out of specifications, replace dual proportioning valve as an assembly.

NOTE:
^ Carefully monitor brake fluid level at master cylinder.
^ Use new "DOT 3" brake fluid.
^ Never reuse drained brake fluid.
