I bled all mine last weekend when I installed my Russel braided lines. All 4 corners will had bubbles comming through no matter how much fluid we put through it. The pedal is firm and the car stops great, but I've never had that experience in 31 years of this stuff. Curious what other here have to say.

The air you're seeing is from the air bleeder connection.

Everytime I use an air bleeder, bubbles are visible but, they are not comming from inside the brake lines. The air line connection is sucking air from around the bleeder screw fitting. As long as the brake pedal feels firm and stops good, you're good to go.

I installed a set of Earl's Solo Bleed bleeder screws and they're the best $20 I ever spent!...

I have seen this happen if you open the bleeder screw too much. It sucks air in around the threads. I only open the bleeder the minimum amount to get fluid flow (about 1/8 turn).

I hate bleeder systems, and do not trust them. If you can get someone inside the car to pump the pedal for you while you bleed, then you know for sure if there is air left or not.

Never used them more than once. No thanx. Only way I do it as a "One Man Operation" is if they have one that is pressurized and screws or clips on like the cover on the reservoir does. With those, you open the bleeder screw and it pushes fluid out under pressure to the reservoir and into the lines
