Hey I'm asking about my 84' F150 w/ the 351w in it.
I've been having a problem for quite some time now that I have pretty much narrowed down to the brakes hanging up, but I have no clue why.
Every now and then the truck will start to pull hard to the right, I can't figure out any particular thing that would be causing the caliper or drum (not sure which one is hanging) since it will do it at times when I haven't just gotten off of the brake pedal or have touched it at all.
I did notice that when I had 36's on, it did not hang up and pull to the right at all- I'm guessing the added weight of the tires had something to do with it. (Note*- I had the 33's on prior the 36's. I had it aligned with the 33's and it still did its pull, slapped the 36's on and it stopped pulling, went back to 33's and the pulling continues)
I do know that I have to replace the master cylinder because it has a slow leak from where it mounts to the booster and will start to drain the back resevoir, but I do not think this is causing the problem since it was doing it before the master ever started leaking.
Tryed to explain the situation the best I could, sorry if it is uncomprehendable. Asked my shop teacher about it since it was previously his work truck, but he has not really given me much more information other then it must one of the brakes hanging up

, so not much help there.
