Re: fading brake pedal
Perfect well at this point i would say that tha abs valve is bypassing fluid. If you can un hook the line that comes into the abs valve and plug it and try and bleed the system where you cap the line going into the abs valve. If you get a good pedal after pluging the line going into the abs valve this tells me that the abs valve is bypassing fluid give it a try i have ran into this a few time and the abs valve has been bad. Also can you rate this sluton also i do hits on my own free time thanks good luck

I have the same problem,, put all new brake components on truck, needed it anyway,, found out that the booster is not designed for a diesel application,, ford made a model change for the diesel,, number from ford is F 5 T Z - 2005 CA a zero loss booster,, have ordered on will put on when arrives, $240. good luck,,
You need to crawl under the truck and inspect each brake line for leaks. You also need to check wheel cylinders and calipers. The chances are pretty good that you will find a small leak in a line or a wheel cylinder leaking, pay close attention to the rear of the truck because that is normally where these problems occur. Hope this helps.
you must have a leak in your brakes! check your brake fluid! They may work for now but after all your brake fluid is pushed out they wont work. You better take a look underneath and get someone to press on the brakes to see where it is leaking out. You can keep toping up the brake fluid and that might get you by for a while.
Adjust your rear brake shoes. Then rebleed the system. Start at the master cylinder Bleed master first then the wheel furthest away from the master (right rear then left rear then right front then left front. Do that and your pedal should be good.
