Can't stop!

[krue]

Here's my problem. I put a booster on my truck about 6 months ago. About 1 month age my front brakes started dragging. Replaced the hose on the pass. side (thought it was the only one draggin, now realize it was both). Sunday in town my brake pedal got real hard as I was coming to intersection, so I stomped it, it let go. I drove around town for ten minutes, then went home. Every time I mashed the brakes it would be different. A few times it was fine, a few it tried to wander off the road, and by the time I got home they were almost gone. I replaced the master cylinder and bled the pi$$ out of them, But I still have nothing. What do I do? I am stumped.

PS Sorry for the long post.

PPS Anyone have the rod that goes from the pedal to the booster? I need one bad!
