Well, it's finally all done. I had to get a better brake bleeder, the rubber fitting that fits OVER the bleeder nipple seems to work the best.
Here are some pics of the old brake lines... They're broken in half at the place of the corrosion.


Note the rusted ends. I'm surprised that the lines held up as long as they did..



And the new lines:


Pretty good job. The toughest part of the whole thing was getting the compression connector tight without twisting the two connecting lines out of the shape they need to be in order to contour the truck.
And after bleeding the brakes, they're back 100%. <img src="/forums/images/graemlins/cheers.gif" alt="" />
