I recently replaced the master cylinder on my (08 ram 2500 6.7 cummins Diesel) and I bleed all my lines and the master cylinder correctly (or so I think) and now my brake pedal is really stiff and when I'm trying to turn at the same time my power steering is locking up on me only when I'm braking and trying to turn. was i supposed to bleed something from the hydro boost lines that feed into the power steering.. anyway for me to diagnosis this before just throwing more money at it and buying a new hydro boost unit and having to get behind master cylinder and dealing with that nightmare.. any help is appreciated
