Depress brake pedal slowly until front brake pressure reading is achieved. Check rear brake pressure. See DUAL PROPORTIONING VALVE PRESSURE SPECIFICATIONS table. If not within specification, replace dual proportioning valve (separated type) or master cylinder assembly (built-in type). Bleed air from system after disconnecting pressure gauges. See BLEEDING BRAKE SYSTEM .
