Will a loose hub cause a brake to lock up?

[Addissimo]

I was having a bit of a problem and I think I just fixed it... I'm just posting this to make sure that i'm on track: My rear driver side hub was a bit loose (as in the tightening bolt on the axle wasn't threaded all the way) and I could be driving my car for a couple days but all of a sudden it would feel like my ebrake was on (not an option because i dont have one at this moment in time) The more i drove the tighter it would get untill I just had to pull over. It happened thrice and this last time i just tightened the shit out of my hub. After letting it sit for a while I could drive it again each time.

I'm wondering if the hub could be the cause of this problem? It would be great to have the peace of mind that I can drive my car again... and thats what this post is for.

Thanks for any input.

I replaced the master cylinder and all is well
