brake problem

[EB]

Had a fair sized load on the bed,6500 lbs, and had a problem stopping. Had it cked out and found the rear axle seals leaking. No problem, replaced them and the rear pads and everything should be ok, right? No way! Now I have a soft petal. If I have the engine off and pump the brake til it is hard and then start the engine the brake will slowly go the floor. Master cyl. , right? Replaced it, same thing. Went to the dealer and they said a code said it was the rear anti lock something. Replaced it, same thing, they are getting a second master cyl. from Dodge, hope it was a bad master cyl. the first time. Anyone got any other ideas? Can't make any $ with my truck in the shop.

Lightly clamp off the rear brake hose [use something to cover hose as to not damage it] If the pedal is up the problem is still in the rear----Sam
