Bleeding ABS brakes
Hello everyone,
Just recently broke a brake line which allowed my master cylinder to run dry. I have since replaced my brake line and refilled my reservoir. I did a typical brake bleed using the 2 person method. Did that about 4 times and got out all the air in my lines. Even with this I only have brakes if I pump them up and slam them. I’ve done a lot of research and found that most people say that there can be air trapped in my abs unit and master. This brings me to wonder if I am able to purge all the air out of those components without bringing it to a dealership and having them run a diagnostics tool that cycles the abs unit. I read that if you use a pressure bleeder it will actually open the abs lines and push the air out of that, into the brake lines allowing me to bleed it. Don’t know if that is true and am looking for some advice.
Thank you,

Still no luck. I did the 2 person method while bleeding the abs lines and then bled the brake lines. Got a little bit of air but nothing else. Appreciate the suggestion though.

ok, ya I think that’s the next best option. I took it to the dealership and they said they can’t bleed my brakes because I have aftermarket brake lines... I bled the master and saw that the front line shot a lot more fluid than the rear did. Do u think this could be a sign of a bad master?

Dont know if this helps but if I drive and then press the brake fully down then release and press again it gets hard and I’m able to brake quickly.

oops, I miss read that. Yes the peddle will stay hard if u pump it then hold it. I am able to build up enough pressure so it will become firm after about 3 pumps.
