I can't get the air out?

[jljbtm]

I've been fixing cars and bleeding brakes for over 30yrs. This is the first one I can't get all the air out.

It's my 99 K2500. I replaced a leaking brake line and just can't get a good pedal back?

Is there something to know or something I don't know here?

if you didnt let the m/cyl empty from gravity you are fine or something blew up when you were bleeding the piss out of it ,,,,,

 

ive bleed newer vehs and it seemed the pedal never felt right until i road tested ,,its hard to explain ,,,

 

you can try bleeding the ABS with a tech2 scanner but thats all i got ,,,,replacing a line shouldnt have givin you any grief ,,,weird

Assuming you have drums in the rear pull the drums and check the cylinders and adjust the shoes. Myself I use a Phoenix Brake Bleeding System.
