Sorry to start a new thread, I've never been good at the searches on these sites,
I replaced the master cylinder and the lines from it to the "distribution block" under th cab and then new lines back out to the front calipers. I can't for thelife of me figure out why I can't get fluid. I can pump all day and nothing. It the "distribution block" also my abs pump and if so am I dead in the water. I don't have a computer for codes and I also came across a proportioning valve depressor, I don't have a clue
