Replaced master cylinder on 94 b4000 and now Ihave no fluid to rear brakes. Any help appreciated. Bled master before installing.
 
You'll need to bleed all 4 corners of the truck as well. You bled the air out of the master and that's good but when you opened the lines to remove the old one air got into the lines. Now is a great time to run fresh fluid through the entire system until clear fluid comes out all bleeder ports.
 
RABS valve is probably effed up and plugged with gunk. I bypassed mine many years ago because of this reason.
