just keep working at them. the air will all come out sooner or later. make sure you dont run the resivor dry and make sure to do all four wheel in the proper order.

i wonder if maybe one of the new lines are sucking air around the threads. it is a thought i had .

When you say you can't get all the air out, how do you know? Spongy pedal? You may have other problems such as running the MC dry and getting air into it. You may need to loosen the lines (individually) at the MC. Have someone slowly depress the pedal then tighten the line while the pedal is to the floor. This is a way of bench bleeding while the MC is still on the truck.

Once you are absolutely sure the MC is bled properly, then move on to bleeding the lines

I had good brakes before but had a wheel cylinder. Leaking so I thought I would change the rubber lines as well when trying to bleed them a lot of air was comming out we never let the mc run out gave up on it that night then got back to it later in the weekend and still can't get all the air out of the lines

so we are talking about front drum brakes? and not front discs on a F250? make sure the new rubber lines you got were for the correct application. were the threads as long as the old ones on the rubber line. did they seat all the way into the wheel cylinder. did the hard lien to the rubber line seat all the way? did it get cross threaded by accident? how did the shoes on the frotn look? were they adjusted out far enough?

are you getting any fluid at all to the wheel cylinders? oh any you may need to bleed the differential valve to recenter it before any fluid will coem to the wheel cylinders in the front. since they were leaking.

If you think you still have air in the lines get a vaccuum type bleeder. Available at most auto parts stores around $30, use it once and you'll never blled brakes without one again.

I had the same exact problem and it turned out to be the MC giving up all of a sudden.
Have a buddy push on the pedal and look in the MC and watch for bubbles from the rear MC seal drawing air in.
Be careful not to get MC shot at your face.

where on the side of the master? near the cap or near one of the lines? if its a line then it needs tightened. if its the cap the master may be going bad.
