I have a 1988 F-350 7.3 idi and I am having stopping issues. I have had a mechanic work on this truck trying to get the brakes to work properly with the following parts all being replaced.
Rear brake shoes, drums, brake parts, rear inner and outer bearings, rear axle seals and both rear brake lines. Popped open the differential and changed the oil with new synthetic oil.
Front brake pads and brake lines replaced, 2 year old master cylinder was replaced along with the power booster and vacuum pump and are all now brand new. All brakes have been bled three times and the old goose neck trailer hydraulic over power brake system was removed.
There are no brake leaks but the soft braking problem remains. The pedal goes three fourths of the way to the floor before I get any braking at all and what little I do have is not enough to stop safely, it actually feels worse than it was before. The is a warning light on the dash that says "Rear Anti-lock" that has been on since I bought this truck a year ago and we replaced the rear ABS brake valve but the light remains lit.
I can think of nothing else to try here that would cause soft braking, the pressure is going somewhere but where? We have bled and bled the whole system and see no air bubbles so I don't think that's the problem. Anyone else have a similar issue or have ideas of what to check next?
