Proportioning Valve
CAUTION:
Check rear brake pressure 2 seconds after front brake pressure reaches specified value. Disconnect ABS actuator harness connector.
NOTE:
Carefully monitor master cylinder fluid level while testing proportioning valve.
Using 2 pressure gauges, attach one to front brake bleeder and one to rear brake bleeder. Bleed air from front and rear bleeders. Depress brake pedal until specified front brake pressure reading is achieved. Check rear brake pressure. See PROPORTIONING VALVE PRESSURE SPECIFICATIONS table. If reading is not as specified, replace dual proportioning valve (separated type) or master cylinder assembly (built-in type).
