After bleeding brakes and still no brakes, what to do.?

i would keep bleeding them, cross, as in left front, right rear, right front, left rear, and keep doing it, it may seem like it is done, but may not be..If you are sure they are completely bled, feel free to gravity bleed them over...then consider the option of the brake booster or master cylinder being on the outs...Why did we replace the lines? and you recheck each connector 110%, i like to use kitty litter on the ground near the connector, as i apply the brakes, engine on, to make sure they stay dry.

Some cars need the ABS system cycled if air got into the system.

What does that mean

Does the brake booster really affect the brakes that much?

How do you get abs cycled

My 97 pathfinder has a 5th bleeder screw in rear breaks. In the middle on top of lines. This is where air gets hung up.
