Brake Bleed procedure for new 00-05 ABS system

[Larry Bastanza]

I am thinking that will be tough. I always bench bleed a master when new. It sounds like maybe due to the fact the master is empty, it needs to be bled on its own first. I am thinking this since if the master is empty and you bleed the wheels there will still be air in the master.

The other thing is with a new master I do not worry about fully pushing it all the way in, I never do that when I bleed a system that has been in use, as mentioned above, I have =seen a few masters fail, due to dirt on the seals and a full depression of the master can cause it to fail.

HTH,

Hey Larry! Surprisingly, I read your old post about the Vacula, and that is why I mentioned it! Quick question for you, is it effective for removing even air stuck in master cylinder if I "accidentally" let it run dry while installing all my hard brake lines? Thanks Larry! Your input is greatly appreciated.

I "accidentally" let mine run dry on the project car too. You can get the air out, but it will take a long time. A vacuum/pressure bleeder will help a lot (I use this one- works great), but due to the dual-piston design of the master cylinder, there may still be voids that are stubborn. You could just take off the cylinder and bench bleed it, or you could try this tool from Cardone, which is specifically designed to push air out of a dual piston master and up through the reservoir. For 10 bucks, I'm going to try the tool before pulling the master off to bench bleed it.

IIRC, at the factory, Honda just puts a huge vacuum on the lines and draws in the fluid. Always wondered how they got away with no bench bleeding at Tochigi, but we all have to do it. Maybe our vacuum tools can't pull enough air?
