Cummins Hydroboost question...need serious help?!
Alright...My buddy has 00 Dodge 3500, automatic, Cummins, 4x4. His brakes went out like he had no assist at all and it would barely stop...it took several hundred feet to stop from 70 and the pedal went all the way to the floor and didn't come back. So I put a new brake booster (hyrdroboost assembly) and a new master cylinder on it and still...no brakes, pedal goes to the floor. I did the whole fill it with fluid turn wheels back and forth turn it off pump pedals a few times and start it...repeat...Well I repeated til I can't repeat any more and still...no brakes. ABS light is on, BRAKE light is on (one in the gauges)...the pedals goes to the floor (making a hissing sound) and then comes back real slow. It is not leaking fluid from anywhere and we bled the brakes. Still nada. I worked on it for several hours AFTER the new parts were installed to no avail...if someone could please help me out or send me in the direction of someone that knows please let me know...hell you can even call my cell phone....I would appreciate any help ya'll can provide.
