I just went through this with my 03 when it blew a line and I replaced the entire set of lines metal and rubber. I got the classic tube set from Summit. You can pressure bleed the system and get 90% of the air out. There will still be air trapped in the antilock controller. The best way to get rid of it is with a scan tool that will run the controller through the bleed cycle. If you can't find a scanner to borrow you can use the gravel/ dirt method. It does work but takes forever. Bleed all you can, you will get a crappy pedal but the truck will stop. On the gravel or dirt nail the gas and get up to about 10 miles and hour and jam the brakes. When the tires lock up you should feel the controller cycle. Now in reverse do the same thing. Repeat five or six times and then rebleed the system with the pressure bleeder. You may have to do this a few times but it does work.
