brakes bled, PEDAL CAME UP HARD, THEN WHEN I STARTED MOTOR THE PEDAL WENT TO THE FLOOR
ABS system has air in it, try bleeding the brakes with the engine running, start with the rabs valve first, then right rear, then left rear, then right front, then left front.
Look at your ABS pump assembly, you should see a bleeder screw on it, that is the rabs valve unit.
Can I vacuum bleed it ?
You can try it, if it still doesn't work the bleed them with the key on or engine running.
I can't see a bleeder!
I am looking at a delphi dbc-7
that's not it!
Then the other system you have to crack the pressure lines one at a time and bleed the air out manually with the key on to force the air out of the unit, then proceed with the rest of the system.
I'll try that, Thanks
