1999 Ford F-350 crew cab 4x4 Cummins mileage: 120,000 truck. My brakes from day one were not the best. I put in a Cummins diesel and now I pull big loads. I can't panic stop and they seem mushy. I replaced everything the vacuum booster, master cylinder, proportioning valve, calipers. Now its worse. I have bled them several times and adjusted my rears up close. Sometimes they shutter when I stop hard and now even pull to one side. I know the R.A.B anti lock things don't work right because my rears will lock up. I don't get any fault codes, now what?
have the same problem?
