I am guessing once you run the ABS and then bleed again it would get any remaining air out.
I finished the job and my pedal is pretty decent.
1. I swapped out the master cylinder and filled with fluid.
2. Waited for it to start seeping out before reconnecting the brake lines. Just snugged them in a little.
3. Had my son pump the brakes and loosened one line at the master at a time until fluid came out. then fully tightened both lines.
4. Then bled all four wheels in this order. Pass rear, Driver rear, Pass front, Driver font. Most of the air bubbles came out during the Pass rear bleed - probably since it was the first one i did.
5. Test drove and went down a big hill with Traction Control engaged to cycle the fluid.
<b>6. Haven't re-bled all four lines again yet but the brakes seem fine.</b> I still have another quart of fresh brake fluid.
So one question I have is once i swap the master out and then bleed, is that bypassing the ABS channels so to speak? I know the lines go thorough the unit but could air go through the lines from the master and get trapped in the ABS ?
The air would have been in the MC and those lines before it hit the ABS unit right? So when i bled, the air bubbles would have been removed via the normal bleed method or could some get trapped in the ABS and then release when i activated the ABS unit via the downhill decent?
