I replaced the calipers and wheel cylinders as well as pads, rotors and drums. I adjusted the star wheel and blead the breaks at all points including the master cylinder and still have weak spongy pedal.
ABS? If so, make sure you bleed that as well. After I did all my bleeding, I still had a soft pedal that would eventually reach the floor. Replaced the MC and all was well.
Why did you have to replace all the slave cylinders? Do you have a shop manual (Haynes, Ford CD, etc.) with a bleed procedure? There's a pattern you should follow.
Brake overhaul was recommended by the Ford dealer on a newly purchased truck. After completing the workI feel that they were probably over zealous in their recommendations but the truck has 130K so I replaced it all and am trying to wrap it up.
I followed the manual and worked from the farthest point to the closest. I then bled the master cylinder and still have the soft pedal.
Could a trip to the dealer with a pressure bleeder work?
From the underside of your truck on a rail, just below the MC, you will see a unit with a brake lines going to it and from it. There is a bleeder valve on it (just smaller than you regular brake bleeders). Bleed it the same way you do your brakes.
