Im trying to get the brakes working after the cab swap and am having some issues. The brakes worked great before the swap and now are very soft, but will harden up some if you pump it. Ive bled them to death, but I'm pretty sure I have air in the master cylinder, since I can see bubbles come up when the peddle is pressed, I assume that is not normal. In the process of the swap the master was unfortunately drained dry, so some air must have gotton in there. So question is, can i just continue to bleed the system to get this air out, or do I have to take it out and bench bleed it? Thanks for any help

 

easiest thing to do is to take off the master and bench bleed. but that is exactly why you have a soft pedal. there are ways to "bench bleed" it on the truck but honestly i cant remember off the top of my head.

 

Im sure that is easier, but i dont have a vice that can hold it, so I was just wondering if doing it in the truck will work, even though it will take longer?

 

you can do it on the truck. if im not mistaken... you do somethin along the lines of slowly pump the brake pedal and loosen the brake line going in to it.
