You have helped so many people in this group I hate to see you going down the same road I did on this brake thing. Before you know it, all the parts will be new and they still wont work. Lets think about this just for a moment before you lose more money.
- We both know brakes very well, there is no magic there. You are going to doubt what you know is right and that is going to cost you like it did me.
- Even if ALL the prop and ABS valves were bad, if the system was full of fluid you would still get SOME pedal. There is nothing in the system that can bleed off all the pressure. Brakes are designed to be fail safe.
- I replaced every stinking piece of my brake system except for the metal lines and they still didnt work. Some of them I replaced SEVERAL TIMES.
- At this point you must know the problem is air in the system and a hell of a lot of it. If I had it to do over again I would get a power bleeder or make my own from an old fluid resivoir lid. This should not be necessary but apparently it is now. A lot of shops have them.
- I finally got some pedal from mine by jacking the rear of the truck up as high as we could get it (way up) and then bled it, the amount of air bubbles was amazing but I'm sure I still have some.
- There is no logical reason to have to have done this.
- Something extremely bizzare is going on and its only in older trucks.
- There MUST be SOMETHING going on inside those metal brake lines and as impossible as that sounds, there is nothing left... at least on mine. I'm sure of it. You might at least dissconnect both sides of one line and blow some compressed air through, you never know what might come out?
If you dont believe this your next posting will read "This is un-real, everything is new and they still dont work" like my first post a few months ago....
Since I dont know what color your truck is I am reserving every color in the spectrum for you other than white because I have that one. Then you can have your own, official "(your color here) Devil"
