Abs Bleeding Procedures

Using conventional manual brake bleeding method (using vinyl tubing and container, with foot pressure on brake pedal), follow sequence in BRAKELINE BLEEDING SEQUENCE table. See Fig 1 or Fig 2 .
Attach one end of tubing to bleeder screw and place other end into container. Have assistant depress and hold pressure on brake pedal. Open bleeder screw 1-2 seconds and then close it. Release pressure on brake pedal. Repeat procedure until air has been discharged from system. See BRAKELINE BLEEDING SEQUENCE table. Bleed each caliper until air bubbles stop appearing from bleeder tubing in fluid bottle. Close bleeder screw. ABS system bleeding is completed.
When air has been removed from all six connections, depress brake pedal using about 66 lbs. (30 kg) force and hold it for about 20 seconds. Check pedal for any unusual movement. Install wheels. Test drive car for 1-2 miles, ensuring proper operation of brakes and ABS system.
